  • Human-Machine Interaction Research @ SirrisTom Tourwé & Elena Tsiporkova het collectief centrum van de Belgische technologische industrie
  • Non-profit & industry-owned collective centre of the technology industry Software & ICTAgile development Variability Semantic technologies Web 2.0 Decision support Innovation process supportIntelligent information retrieval Knowledge extraction Data integration Business intelligence Human machine interaction
  • HMI research @ SirrisPro-active decision support Multimodal Context-sensitive Interusable, multi-platform & multi-device
  • 2 large industry-driven European R&D projects
  • ASTUTE Pro-active decision support in data-intensive environments Pro-actively push relevant Present information in a user-specifc information and context-aware wayOptimise the choices available Keep the user in control Provide the right dosage of Implement intention-aware adaptive information at the right time automation (trading of control)
  • Smart Emergency Dispatching• A decentralized solution is targeted where: • the emergency workers are equipped with portable or embedded devices capable of receiving, sending, and visualizing dispatching events and context information such as annotated geographical maps • the emergency workers collaborate within their task force and between different units backed by a central dispatching room • a map-centric user interface provides the field workers with a clear and up-to-date overview of all events. Field workers Dispatching room
  • Adaptive Multimodal Interfaces• The main goal of the user interface design task is to enable applications to adapt to changing situational contexts, e.g. • to send an alert to the commander when one of his firemen approaches toxic substances in the building, • through an optimal output modality, taking into account environmental conditions such as noise and lighting level • as well as an appropriate input modality, to allow the commander to immediately take the appropriate action
  • Multimodal Interface Design• The multimodal user interface design is supposed to provide solutions to design problems such as: • When to use certain modality? • How to combine multiple modalities? • How to adapt the modality according to its context of use?• Formal principles and guidelines(1): • design for the broadest range of users and contexts of use • address privacy and security • maximise human cognitive and physical abilities • integrate modalities in a manner compatible with user preference, context, and system functionality • …(1) L.M. Reeves, J. Lai, J.A. Larson, S. Oviatt, TS Balaji, S. Buisine, P. Collings, P. Cohen, B. Kraal, J.C. Martin, etal. Guidelines for multimodal user interface design. Communications of the ACM, 47(1):57–59, 2004.
  • Theory (formal guidelines) vs. practice• Different experts might approach the same interface design tasks in different ways based on personal expertise, background and intuition• Guidelines resulting from research do not capture the considerable practical experience and expert knowledge that interface designers rely on during their daily activities• Existing formal guidelines mostly focus on high-level design objectives • are not specific to multi-modality • do not include justification for the made recommendations • lack information about how to move from guidelines to a concrete implementation
  • Need for Knowledge Capture and Modelling• Capture and document design best practices• Can be used as a reference while designing, reducing time and increasing quality of the design solutions• Keep track of knowledge and expertise along projects• Can be used for communication and education of team (developers, designers, etc.)• To be used and reused, going towards standardization
  • Ontology-driven Knowledge Modelling: Levels of Modelling Abstraction Scenario-specific types of Core domain concepts: HCI community: design users, activities, tasks andfactual information on users, guidelines and best concrete working applications & devices practices environment Domain Expert knowledge Application knowledge knowledge
  • Capturing Domain Knowledge Core domain concepts: Domain knowledge is described via an ontology, afactual information on users, formal representation of knowledge by a set of key applications & devices domain concepts and the relationships between those concepts. Domain knowledge
  • Modeling Design GuidelinesDesign guidelines (expert HCI community: designknowledge) are captured guidelines and bestvia the Semantic Web Rule practicesLanguage (SWRL) Expert knowledgeApplication(?application), NoisyLocation(?location), used_in(?application, ?location) -> cannot_use_modality(?application, audio_output), cannot_use_modality(?application, voice_input)
  • Modelling Application KnowledgeThe original core ontology is complementedand extended by creating an ontology with Scenario-specific types of users, activities, tasks andrelevant application-specific knowledge: concrete working• types of users involved environment fire fighters, fire commanders, fire station dispatchers, air sampling collectors, emergency communication managers, medical experts, company Application employees knowledge• their activities and tasks fire fighting, locating water supplies, rescuing company employees that could not leave a building, logging relevant information, defining security perimeters in the presence of dangerous substances• working environment they are located in an administrative office where the fire started, a storage facility with smoke and high temperatures, outside a building where dangerous substances might be being spread in the air, inside a medicalised tent.
  • Summary• A semantic modelling framework • allowing to capture the domain and expert knowledge available within the Human-Computer Interaction (HCI) community • supporting HCI designers in selecting the most appropriate (combination of) modalities during their daily design tasks • enabling the high-level concrete description of multimodal HMI design patterns• Work in progress
  • Smarcos Smart composite human-computer interfaces• Smarcos aims to ensure interusability of interconnected embedded systems• UI designs of new applications and services must accommodate various devices, personal preferences, and adaptivity to different use contexts to make the user experience both utilitarian and pleasant
  • Our contributionContext-aware feedback delivery• A technological framework for enabling multi-platform & multi-device systems to adapt feedback delivery to situational contexts • send the right information • at the right moment in time • through a device that offers the optimal output modality for that information • as well as an appropriate input modality to allow the user to react
  • Requirements & challenges• Measure the availability of the user for feedback (right moment) • taking into account time of the day, current and future activities, social & professional environment, … • in order to determine whether to deliver feedback right away, or time-shift it to a later moment in time• Determine the available devices (right device) • taking into account surrounding active devices, device characteristics, available input/output modalities, … • in order to select the most appropriate device for delivering feedback taking into account its capabilities• Adapt the message delivery (right information) • taking into account the availability of the user, chosen modality, message form and output device capabilities, … • in order to tailor the content and functionality toward the selected device capabilities
  • A declarative rule-based solution• Determining timing, device and message format requires modelling a complex piece of logic, i.e. • under which combination of the many different context parameters is a particular solutions prefered? • a user’s current & future activities, and his location • his physical & social environment (noise, light, temperature, presences of colleagues, …) • the devices surrounding him, their characteristics and capabilities • the message’s urgency level• Requires a reactive system that continuously monitors & evaluates the context • extend & complement the traditional imperative paradigm (if- then-else) with a declarative rule-based paradigm
  • Attentive Personal Systems
  • Basic example scenario The Smarcos system detects that a user has not taken hismedication and immediately sends an urgent pill reminder. Theuser is currently commuting to the office and only carries his mobile phone. The system decides to send a text message. It knows that the user normally arrives after half an hour at hisdesk, and when he starts using his computer, he gets another reminder to which he needs to react.
  • When is a message urgent?Message urgency = HIGH if> The message needs to be delivered to the user in 10 minutes or less
  • When do we disturb a user?User availability = LOW if> The user is in a meeting at the office> The user is on the go (e.g. commuting to work)
  • How do we deliver an urgent message to auser with low availability?> send message to mobile phone immediately> send reminder message to other device when available later
  • When do we deliver scheduled messages?• The users availability is not LOW• A device becomes available
  • When does a device become available?Device = AVAILABLE if• It is in the same location as the user> It is a mobile device (always available)
  • Summary• A declarative rule-based framework that • continuously monitors & evaluates the context, and acts correspondingly according to the defined strategies • decouples complex logic from other application concerns, which leads to easier maintainability and understandability • can be evolved in a flexible and incremental way• Integrated into a more complex technology stack to enable context-aware feedback delivery • sensor layer, interconnectivity layer, context interpretation layer, …
