TRANSCRIPT
Mobile Interfaces
• What is different– Users are on the go
• Attention often needs to be paid to surroundings (walking, driving, etc.) rather than the interface
– Devices tend to be smaller• Smaller displays, less power, etc.
• Design implications– Do not use the standard keyboard/mouse interaction
• Touch screens, speech
– Incorporate alternative modes of feedback (audio cues, vibrate/tactile)
Common Applications
• Travel support– Maps, traffic, turn-by-turn guidance
• Local information– Service availability & ratings, etc.
• Coordination among users– Locating and meeting others, synchronizing
distributed activity
Issues
• Systems and interfaces must assume – Reduced network connectivity (gaps in coverage
and limited bandwidth)– Variance in precision of location information
