User interface development life cycle often involves several different views of the user interface over time; these views belong sometimes to different abstraction levels. Usually the relationship between views is presented by tiling coordinated windows, which leaves to the developer the responsibility to effectively and efficiently link corresponding elements across views. This paper attempts to overcome the shortcomings posed by the coordinated visualization across views by providing UsiView, a rendering engine that ensures with one single window an animated transition between three different user interface views: the internal, the external, and the conceptual one. Examples of scenarios include: an authoring environment providing an animated transition from an internal view (e.g., HTML5) to its external view (e.g., a web page), an Integrated Development Environment providing an animated transition from its conceptual view to its external view; a model-driven engineering environment providing an animated transition from the conceptual view to an external view. A five-step methodology for specifying animated transitions between views is proposed: defining the views, their mappings, the transition expressing the mappings, and the animation technique to render such transition. This paper discusses the potential advantages of using animated transitions between user interface views during the development life cycle

A comparison of component-based software engineering and model-driven develop...Nikolay Grozev
Component-based software engineering (CBSE) and model-driven development (MDD) are two approaches for handling software development complexity. In essence, while CBSE focuses on the construction of systems from existing software modules called components; MDD promotes the usage of system models which after a series of transformations result with an implementation of the desired system. Even though they are different, MDD and CBSE are not mutually exclusive. However, there has not been any substantial research about what their similarities and differences are and how they can be combined. In this respect, the main goal of this thesis is to summarize the theoretical background of MDD and CBSE, and to propose and apply a systematic method for their comparison. The method takes into account the different effects that these development paradigms have on a wide range of development aspects. The comparison results are then summarized and analyzed.
The thesis also enriches the theoretical discussion with a practical case study comparing CBSE and MDD with respect to ProCom, a component model designed for the development of component-based embedded systems in the vehicular-, automation- and telecommunication domains. The aforementioned comparison method is refined and applied for this purpose. The comparison results are again summarized, analyzed and proposals about future work on ProCom are made.

Pipe-Filter Architecture Style
The high-level design solution is decomposed into two “generic” parts (filters and pipes):
Filter is a service that transforms a stream of input data into a stream of output data.
Pipe is a mechanism or conduit through which the data flows from one filter to another.
Input

Event Driven (Real Time)
The high-level design solution is based on an event dispatcher, which manages events and the functionalities that depend on those events. These have the following characteristics:
Events may be a simple notification or may include associated data.
Events may be prioritized or be based on constraints such as time.
Events may require synchronous or asynchronous processing.
Events may be “registered” ...

This case study reviewed the challenges of developing a style guide (covering both interaction and visuals) to guide the design of future applications. Although the general usage context and audience could be inferred from existing web applications, no specific information regarding future workflows was available. The style guide therefore took the form of a framework that empowers non-UCD experts to design consistent and learnable applications – thereby increasing data integrity, as well as reducing stress and frustration for the end-users.

Model-based engineering of multi-platform, synchronous & collaborative UIsJean Vanderdonckt
The paper describes an engineering method for building user interfaces for ubiquitous environments. The method comprises of several extensions in the UsiXML family
of modes as well as design and runtime support so as to enable multi-platform, synchronous and collaborative interactions. We demonstrate key concepts of the method and their application by elaborating a scenario of collaborative co-play
of the ‘tic-tac-toe’ game. The specific use case features synchronous co-engagement in game play by remote users (players or observers) using desktop PCs or Android devices.
Model-Driven Engineering of User Interfaces: Promises, Successes, Failures, a...Jean Vanderdonckt
Model-driven engineering (MDE) of user interfaces consists in describing a user interface and aspects involved in it (e.g., task, domain, context of use) in models from which a final interface is produced. With one big win in mind: when the user’s requirements or the context of use change, the models change accordingly and so does the supporting user interface. Models and a method for developing user interfaces based on MDE are presented in this tutorial supporting forward engineering (a new interface is produced), reverse engineering (an existing interface is improved), and lateral engineering (an existing interface is adapted to a new context of use). Software supporting this method will be used based on UsiXML (User Interface eXten-sible Markup Language), a XML-compliant user interface description language.

Engineering the Transition of Interactive Collaborative Software from Cloud C...Jean Vanderdonckt
Paper presented at EICS '22: https://dl.acm.org/doi/10.1145/3532210
The "Software as a Service" (SaaS) model of cloud computing popularized online multiuser collaborative software. Two famous examples of this class of software are Office 365 from Microsoft and Google Workspace. Cloud technology removes the need to install and update the software on end users' computers and provides the necessary underlying infrastructure for online collaboration. However, to provide a good end-user experience, cloud services require an infrastructure able to scale up to the task and allow low-latency interactions with a variety of users worldwide. This is a limiting factor for actors that do not possess such infrastructure. Unlike cloud computing which forgets the computational and interactional capabilities of end users' devices, the edge computing paradigm promises to exploit them as much as possible. To investigate the potential of edge computing over cloud computing, this paper presents a method for engineering interactive collaborative software supported by edge devices for the replacement of cloud computing resources. Our method is able to handle user interface aspects such as connection, execution, migration, and disconnection differently depending on the available technology. We exemplify our approach by developing a distributed Pictionary game deployed in two scenarios: a nonshared scenario where each participant interacts only with their own device and a shared scenario where participants also share a common device, including a TV. After a theoretical comparative study of edge vs. cloud computing, an experiment compares the two implementations to determine their effect on the end user's perceived experience and latency vs. real latency
UsyBus: A Communication Framework among Reusable Agents integrating Eye-Track...Jean Vanderdonckt
Presentation of ACM EICS '22 paper: https://dl.acm.org/doi/10.1145/3532207
Eye movement analysis is a popular method to evaluate whether a user interface meets the users' requirements and abilities. However, with current tools, setting up a usability evaluation with an eye-tracker is resource-consuming, since the areas of interest are defined manually, exhaustively and redefined each time the user interface changes. This process is also error-prone, since eye movement data must be finely synchronised with user interface changes. These issues become more serious when the user interface layout changes dynamically in response to user actions. In addition, current tools do not allow easy integration into interactive applications, and opportunistic code must be written to link these tools to user interfaces. To address these shortcomings and to leverage the capabilities of eye-tracking, we present UsyBus, a communication framework for autonomous, tight coupling among reusable agents. These agents are responsible for collecting data from eye-trackers, analyzing eye movements, and managing communication with other modules of an interactive application. UsyBus allows multiple heterogeneous eye-trackers as input, provides multiple configurable outputs depending on the data to be exploited. Modules exchange data based on the UsyBus communication framework, thus creating a customizable multi-agent architecture. UsyBus application domains range from usability evaluation to gaze interaction applications design. Two case studies, composed of reusable modules from our portfolio, exemplify the implementation of the UsyBus framework.
µV: An Articulation, Rotation, Scaling, and Translation Invariant (ARST) Mult...Jean Vanderdonckt
Paper presented at ACM EICS '22
Finger-based gesture input becomes a major interaction modality for surface computing. Due to the low precision of the finger and the variation in gesture production, multistroke gestures are still challenging to recognize in various setups. In this paper, we present µV, a multistroke gesture recognizer that addresses the properties of articulation, rotation, scaling, and translation invariance by combining $P+'s cloud-matching for articulation invariance with !FTL's local shape distance for RST-invariance. We evaluate µV against five competitive recognizers on MMG, an existing gesture set, and on two new versions for smartphones and tablets, MMG+ and RMMG+, a randomly rotated version on both platforms. µV is significantly more accurate than its predecessors when rotation invariance is required and not significantly inferior when it is not. µV is also significantly faster than others with many samples and not significantly slower with few samples
RepliGES and GEStory: Visual Tools for Systematizing and Consolidating Knowle...Jean Vanderdonckt
The body of knowledge accumulated by gesture elicitation studies (GES), although useful, large, and extensive, is also heterogeneous, scattered in the scientific literature across different venues and fields of research, and difficult to generalize to other contexts of use represented by different gesture types, sensing devices, applications, and user categories. To address such aspects, we introduce RepliGES, a conceptual space that supports (1) replications of gesture elicitation studies to confirm, extend, and complete previous findings, (2) reuse of previously elicited gesture sets to enable new discoveries, and (3) extension and generalization of previous findings with new methods of analysis and for new user populations towards consolidated knowledge of user-defined gestures. Based on RepliGES, we introduce GEStory, an interactive design space and visual tool, to structure, visualize and identify user-defined gestures from a number of 216 published gesture elicitation studies

Intra-platform plasticity regularly assumes that the display of a computing platform remains fixed and rigid during interactions with the platform in contrast to reconfigurable displays, which can change form depending on the context of use. In this paper, we present a model-based approach for designing and deploying graphical user interfaces that support intra-platform plasticity for reconfigurable displays. We instantiate the model for E3Screen, a new device that expands a conventional laptop with two slidable, rotatable, and foldable lateral displays, enabling slidable user interfaces. Based on a UML class diagram as a domain model and a SCRUD list as a task model, we define an abstract user interface as interaction units with a corresponding master-detail design pattern. We then map the abstract user interface to a concrete user interface by applying rules for the reconfiguration, concrete interaction, unit allocation, and widget selection and implement it in JavaScript. In a first experiment, we determine display configurations most preferred by users, which we organize in the form of a state-transition diagram. In a second experiment, we address reconfiguration rules and widget selection rules. A third experiment provides insights into the impact of the lateral displays on a visual search task.

We conducted a user-centered design of a clinical decision-support system for breast cancer screening, diagnosis, and reporting based on stroke gestures. We combined knowledge elicitation interviews, scenario-focused questionnaires, and paper mock-ups to understand user needs. Multi-fidelity (low and high) prototypes were designed and compared first in vitro in a usability laboratory, then in vivo in the real world. The resulting user interface provides radiologists with a platform that integrates domain-oriented tools for the visualization of mammograms, the manual, and the semi-automatic annotation of breast cancer findings based on stroke gestures. The contribution of this work lies in that, to the best of our knowledge, stroke gestures have not yet been applied to the annotation of mammograms. On the one hand, although there is a substantial amount of research done in stroke-based interaction, none focuses especially on the domain of breast cancer annotation. On the other hand, typical gestures in breast cancer annotation tools are those with a keyboard and a mouse
Simplifying the Development of Cross-Platform Web User Interfaces by Collabo...Jean Vanderdonckt
Ensuring responsive design of web applications requires their user interfaces to be able to adapt according to different contexts of use, which subsume the end users, the devices and platforms used to carry out the interactive tasks, and also the environment in which they occur. To address the challenges posed by responsive design, aiming to simplify their development by factoring out the common parts from the specific ones, this paper presents Quill, a web-based development environment that enables various stakeholders of a web application to collaboratively adopt a model-based design of the user interface for cross-platform deployment. The paper establishes a series of requirements for collaborative model-based design of cross-platform web user interfaces motivated by the literature, observational and situational design. It then elaborates on potential solutions that satisfy these requirements and explains the solution selected for Quill. A user survey has been conducted to determine how stakeholders appreciate model-based design user interface and how they estimate the importance of the requirements that lead to Quill
Detachable user interfaces consist of graphical user interfaces whose parts or whole can be detached at run-time from their host, migrated onto an- other computing platform while carrying out the task, possibly adapted to the new platform and attached to the target platform in a peer-to-peer fashion. De- taching is the property of splitting a part of a UI for transferring it onto another platform. AttAaching is the reciprocal property: a part of an existing interface can be attached to the currently being used interface so as to recompose another one on-demand, according to user's needs, task requirements. Assembling inter- face parts by detaching and attaching allows dynamically composing, decom- posing and re-composing new interfaces on demand. To support this interaction paradigm, a development infrastructure has been developed based on a series of primitives such as display, undisplay, copy, expose, return, transfer, delegate, and switch. We exemplify it with QTkDraw, a painting application with attach- ing and detaching based on the development infrastructure.
The Impact of Comfortable Viewing Positions on Smart TV GesturesJean Vanderdonckt
Whereas gesture elicitation studies for TV interaction
assume that participants adopt an upright, frontal viewing
position, we asked 21 participants to hold a natural, comfortable
viewing position, the posture they adopt when watching TV
at home. By involving a broad selection of users regarding
age, profession, our study targets a higher ecological validity
than in existing studies. Agreements rates were lower than existing studies using an upright, frontal viewing position. Participants experienced problems due to (1) having to use their slave hand instead of their dominant hand, (2) being in a certain orientation with their head making it more difficult to perform some physical movements, and (3) being hindered in their movement by the sofa there lay on. Since each person may have a different
position inducing different gestures due to the aforementioned
problems, the effect of a comfortable viewing position is analyzed
by comparison to gestures for a frontal position.
Head and Shoulders Gestures: Exploring User-Defined Gestures with Upper BodyJean Vanderdonckt
This paper presents empirical results about user-dened gestures
for head and shoulders by analyzing 308 gestures elicited from 22 participants for 14 referents materializing 14 different types of tasks in IoT context of use. We report an overall medium consensus but with medium variance (mean: .263, min: .138, max: .390 on the unit scale) between participants gesture proposals, while their thinking time were less similar (min: 2.45 sec, max: 22.50 sec), which suggests that head and shoulders gestures are not all equally easy to imagine and to produce. We point to the challenges of deciding which head and shoulders gestures
will become the consensus set based on four criteria: the agreement rate, their individual frequency, their associative frequency, and their unicity.

G-Menu: A Keyword-by-Gesture based Dynamic Menu Interface for SmartphonesJean Vanderdonckt
Instead of relying on graphical or vocal modalities for searching
an item by keyword (called K-Menu), this paper presents the G-Menu exploiting gesture interaction and gesture recognition: when a user sketches a keyword by gesturing the first letters of its label, a menu with items related to the recognized letters is constructed dynamically and presented to the user for selection and auto-completion. The selection can be completed either gesturally by an appropriate gesture (called the G-Menu) or by touch only (called the T-Menu). This paper compares the three types of menu, i.e., by keyword, by gesture, and by touching, in a user study with twenty participants on their item selection time (for measuring task efficiency), their error rate (for measuring task effectiveness),
and their subjective satisfaction (for measuring user satisfaction).

Unistroke and multistroke gesture recognizers have always striven to reach some robustness with respect to
all variations encountered when people issue gestures by hand
on touch surfaces or with sensing devices. For this purpose,
successful stroke recognizers rely on a gesture recognition
algorithm that satisfies a series of invariance properties such
as: stroke-order invariance, stroke-number invariance, stroke direction invariance, position, scale, and rotation invariance.
Before initiating any recognition activity, these algorithms
ensure these properties by performing several pre-processing
operations. These operations induce an additional computational
cost to the recognition process, as well as a potential error
bias. To cope with this problem, we introduce an algorithm that
ensures all these properties analytically instead of statistically
based on a vector algebra. Instead of points, the recognition
algorithm works on vectors between vectors. We demonstrate
that this approach not eliminates the need for these preprocessing
operations but also satisfies an entire structure preserving
transformation.

Body-based gestures, such as acquired by Kinect sensor, today benefit from efficient tools for their recognition and development, but less for automated reasoning. To facilitate this activity, an ontology for structuring body-based gestures, based on user, body and body parts, gestures, and environment, is designed and encoded in Ontology Web Language according to modelling triples (subject, predicate, object). As a proof-of-concept and to feed this ontology, a gesture elicitation study collected 24 participants X 19 referents for IoT tasks = 456 elicited body-based gestures, which were classified and expressed according to the ontology.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

4. Motivations
Software development life cycle typically involves many
steps at various levels of abstraction
In Model-Driven Architecture (MDA), 3 levels of abstraction
Computing-Independent Model (CIM)
Platform-Independent Model (PIM)
Platform-Specific Model (PSM)
User Interface (UI) development life cycle is similar
In UI development according to Cameleon Reference Framework
(CRF), 4 levels of abstraction
Task and domain models
Abstract User Interface (AUI) model
Concrete User Interface (CUI) model
Final User Interface
In Model-based UI design, the mapping problem
Task, domain, presentation, dialog, help, tutorial
AVI'2012 - Capri, May 21-25, 2012
5. Motivations
Transition between steps, levels is hard to grasp
(imagine, understand, maintain, evolve)
Models found at each level are different: concepts, relationships,
and attributes are different
Models may have different views depending on
The stakeholder (designer, marketing, end user)
The step (e.g., early design vs advanced design)
The concepts (e.g., level of details)
Transitions between models are complex
E.g., mappings, transformations in MDA
Consequences
Mode switching is frequent
Cognitive load is high
Learning curve is slow

20. Shortcomings of UI views organisation
Almost no links represented between views
When links are represented
Legibility problems
Scalability problems
Variation of link representations
Line, arrows, table, graph, tree
No immediate feedback
High cognitive load
AVI'2012 - Capri, May 21-25, 2012
21. Goal
Replace links between UI views by an animated
transition
AVI'2012 - Capri, May 21-25, 2012
22. Methodology
1) Define the initial view
2) Define the final view
3) Define mappings between views
4) Derive the transition based on mappings
previously defined
AVI'2012 - Capri, May 21-25, 2012
25. Methodology
5) Identify animation technique to produce the
transition
Text-to-text
Text-to-color
Text-to-shape
Disappearing elements
6) Execute the animated transition

AVI'2012 - Capri, May 21-25, 2012
30. Results
UsiView
Supports animated transitions between three UI
views: internal, external, conceptual
Is implemented in Microsoft Expression Blend
An animated transition is actually a visual effect between two vectorial
graphical objects in MS Blend governed by parameters
Location
Speed
Acceleration - Deceleration
Reduces the cognitive load of mode switching
AVI'2012 - Capri, May 21-25, 2012
31. Conclusion and Future Work
Animated transitions are a viable approach for
depicting the behaviour of some phenomenon
For a change of context
Between an initial and a final state
Provided that
Temporal aspects are well designed
Spatial aspects are adequately programmed
Effects are derived from the model views, not randomly
Transition types: to be extended
End user studies: to be pursued
Still no systematic approach for animated
transitions
