Overview

Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them.

Use and Context

⁄  U1 Human Social Organization and Work ⁄  U2 Application Areas ⁄  U3 Human-Machine Fit and Adaptation

The uses to which computers are put are spoken of as 'applications‘ (U2) in the computer world. These uses and the extent to which the interface (and the application logic in the rest of the system) fits (U3) them can have a profound impact on every part of the interface and its social, work, and success. Moreover, the general business context (U1) may be important.

human as an interacting ⁄  U1 Relates to the social being. It includes a concern with the nature of work, and with the notion that human systems and technical systems mutually adapt to each other and must be considered as a whole. ⁄  E.g. models of work, workflow, cooperative activity, office work

⁄  U2 The focus of this section is on classes of application domains and particular application areas where characteristic interfaces have developed. ⁄  E.g. characterization of application areas (e.g., individual vs. group, paced vs. unpaced) ⁄  E.g. on-line tutorial systems and help systems

⁄  U3 Part of the purpose of design is to arrange a fit between the designed object and its use. Adjustments can be made (1) either at design time or at time of use (2) by either changing the system or the user and (3) the changes can be made by either the users themselves or, sometimes, by the system. ⁄  E.g. user guidance: help techniques, documentation, error-handling techniques ⁄  E.g. adaptive systems

⁄  H1 Human Information Processing ⁄  H2 Language, Communication, Interaction ⁄  H3 Ergonomics

It is important to understand something about human human information-processing characteristics, how action (H1) is structured, the nature of human communication (H2), and human physical and physiological requirements (ergonomics, H3).

⁄  H1 Characteristics of the human as a processor of information. ⁄  E.g. learning ⁄  E.g. motor skills

communication and ⁄  H2 Language as a interface medium. Communication phenomena. ⁄  E.g. graphical interaction language

Anthropometric and physiological ⁄  H3 characteristics of people and their relationship to workspace and environmental parameters. ⁄  E.g. arrangement of displays and control ⁄  E.g. fatigue and health issues

Interface

⁄  C1 Input and Output Devices ⁄  C2 Dialogue Techniques ⁄  C3 Dialogue Genre ⁄  C4 Computer Graphics ⁄  C5 Dialogue Architecture

Machines have specialized components for interacting with basically humans. Some of these components are transducers for moving information (C1) physically between human and machine. Other components have to do with the control structure and representation of aspects of the interaction (C2-C5).

⁄  C1 The technical construction of devices for mediating between humans and machines. ⁄  Everything about output and input devices ⁄  In our case: Hands on a surface

⁄  C2 The basic software architecture and techniques for interacting with humans. gesture ⁄  E.g. touch-based input techniques, ⁄  E.g. scrolling and panning display

⁄  C3 The conceptual uses to which the technical means are put. Such concepts arise in any media discipline (e.g., film, graphic design, etc.). ⁄  E.g. tool metaphor ⁄  E.g. personae, point of view ⁄  E.g. workspace models

⁄  C4 Basic concepts from computer graphics that are especially useful to know for HCI. ⁄  E.g. solid modeling, splines, surface modeling, hidden surface removal …

⁄  C5Software architectures and standards for user interfaces. ⁄  E.g. multi-user interface architectures "Look and feel“ ⁄  E.g. standardization and interoperability

Design

⁄  D1 Design Approaches ⁄  D2 Implementation Techniques ⁄  D3 Evaluation Techniques ⁄  D4 Example Systems and Case Studies

The construction of human interfaces is both a matter of design and engineering. These topics are concerned with the methodology and practice of interface design (D1). Other aspects of the development process include the relationship of interface engineering (both development to the software and hardware, D2-D4) of the rest of the system.

⁄  D1 The process of design. Relevant topics from other design disciplines. ⁄  E.g. typography ⁄  E.g. use of color ⁄  E.g. temporal sequencing ⁄  E.g. industrial design basics

⁄  D2 Tactics and tools for implementation. ⁄  E.g. prototyping techniques ⁄  E.g. object-oriented methods ⁄  E.g. data representation and algorithms

⁄  D3 Philosophy and specific methods for evaluations. ⁄  E.g. productivity ⁄  E.g. usability testing ⁄  E.g. interviewing techniques

⁄  D4 Classic designs to serve as extended examples of human interface design. ⁄  E.g. everything we visited in Phase 1: Inspiration - Microsoft Surface, iPhone, Jeffrey Han, Mice, CLI, historic keyboards

⁄  Next Milestone (#3) ⁄  Please send me your presentations! ⁄  Concentrate on the relevant HCI areas ⁄  Choose some of those areas to be described in the concept ⁄  Detail the concept along the chosen areas ⁄  Written, with graphics, with images …
