  1. The Future of Mobile Device Research in HCI Jacob O. Wobbrock Human-Computer Interaction Institute School of Computer Science Carnegie Mellon University

  2. Trends • “Gap” between user and desktop widening • Both in time and space • Widespread mobile device proliferation • Mobile phones achieve huge penetration in Africa (Ferrett ’04) • Mobile device use is more intermittent than desktop use • Mobile devices are used in a wider variety of contexts • Environmental, social, contextual factors become increasingly important • Convergence of computing capabilities onto the phone • Take photos, play music, record notes, etc. • Our society is aging • 12% is 65+ in 2000; 20% will be 65+ in 2030; 419 million by 2050 • Accessibility of mobile devices will be an issue • .: Consider device context, not just capability

  3. Research Responses • Improve mobile device accessibility • Small devices • Miniature buttons, keys • Tiny fonts • Postage-stamp screens • Low pixel counts • Poor contrast • Understand, sense, and adapt to “situational impairments” • Orientation • Light level, glare • Temperature • Vibration, walking • Gloves • Noisy environment • User attention/distraction?

  4. Research Responses • Ubi-input • “Learn once, write anywhere” • Sensors everywhere • Many things will need some rudimentary input • Don’t want to learn a new technique for every new device • Simple, extensible techniques applicable to a variety of devices • MDITIM (Isokoski ’00), EdgeWrite (Wobbrock ’03) • Deliver education and medical information on mobile phones • Particularly in developing nations
