Multidisciplinary Research in HCI Engineering: Cases Studies Ahmed Seffah, Associate Professor Human-Centered Software Engineering Group Department of Computer Science and Software Engineering Concordia University, Montreal Canada 1/27 Outlines 1. HCI Engineering: A Multidisciplinary Field 2. Multidisciplinary research – HMD – P-Tab – Bio-Use 3. Concluding Remarks 2/27 Human Computer Interface: Today and Tomorrow BlazerJet Computing Platforms Wearable and Immersive Computing GUI CardPC, GPS, GSM 'phone, a novel Pinger receiver and both the audio interface and a Jornada 420 palmtop. Mobile Multiple User Interface, Cross-Platforms and Computing Interaction Mobile UI Multi-Devices Applications [Seffah and Tangible, Style Javahery, Wiley and Sons 2006] Sensing UI Web UI Handheld Computing Stationary Office Computers 3/27 HCI: A Multidisciplinary Research Field Human Computer Interaction Engineering Task and Workflow Analysis Semiotics Interaction Devices and Styles Communication Design and Prototyping Computer Science Education Usability Testing and Empirical Studies Software Engineering Cognitive Process and User Modeling Industrial Design Cognitive Psychology Fine Arts Commerce Sociology Anthropology Relationships between Technology, Work, and Organization Computer Supported Collaborative Work Human Factors Engineering Building Engineering Virtual Communities Affective and Persuasive Computing 4/27 Usability: The Ultimate Goal in HCI Engineering • Not GUI, not user friendly • Quality factor like reliability, safety, scalability, etc. • The extent to which, a product can be used by a set of users to achieve their tasks with effectiveness, efficiency and satisfaction in a certain context of Use [ISO-IEEE standards] • Measurable attributes 5/27 Human-Centered Software Engineering [Seffah, et all., Kluwer/Springer, 2005] 1. Observe, capture, and analyze observational data on human behaviors and experiences 2. Measure human performance, effectiveness, satisfaction, learnability, comprehension 3. Using these data and observations to quantify and model user and user interface 4. Extract design patterns and build conceptual proof of concepts design 5. Integrate these patterns and models into the software development practices 6/27 HMD, P-Tab and Bio Use Projects • Experimental frameworks • A unified environment to visualize data, complex artifacts and phenomena – From usability to visual comprehension – From GUIs to Tangible UI; Real objects to represent computerized entities – From WIMP to sensing-based interaction 7/27 HMD Project • Digital art work by Char Davis • Breathing and body movements as a way for exploration • Funded by an NSERG New Media Grant • 4 professors: HCI/Software Engineering, Graphics/Computer Science, Industrial Design, Mechanical Engineering 8/27 HMD 9/27 Bio Use • LIMSI-Every Genepole, Bioinformatics Team • Virtual Reality Setting to visualize factual and structural genomic data • Biologists (Concordia, Orsay, Genepole), Bioinformatician (Dr. Gherbi), Usability/HCI (Dr. Seffah) • Partial funds (Collaboration France/Quebec) 10/27 Bio-Use 11/27 PTab • Physical table that embeds a large smart board, stereoscopic glasses, hand sensors to visualize a complex phenomena such as a design using tangible objects • HCI/Usability (Ahmed Seffah), Digital Sounds/Image Artist (Jason Lewis) – Ecole Centrale de Lyon • Funded Concordia SEED, NSERG, Hexagram (Arts) 12/27 Proposed Controlled Experiments Protocol 13/27 Concordia Usability Testing Lab 14/27 A Demo 15/27 Quantitative Results 16/27 Concluding Remarks: Keys factors for multidisciplinary research • Open mind researcher! • Minimum knowledge and cross-disciplines terminology • Strong management and leadership skills • Highly qualified personnel: training and hiring • Funds availability! 17/27 Merci Thank you Questions 18/27
