1. Applied Pervasive Computing Presentation : Mobile Interaction Devices

2. Agenda Definition Device types Capabilities Weaknesses History Main platforms Development tools

3. Definition We define a mobile interaction device as a medium for creating mobile interactive applications. It is an important enabling technology for pervasive and ubiquitous computing systems

4. Device Types Typical examples: Cell phones Personal digital assistants (PDA’s) Smart phones (iPhone, Android) Other examples Intelligent watches Intelligent clothing

5. Capabilities Highly mobile Independent of power grid * Many sensors GPS (General Positioning System) Accelerometer Gyroscope Magnetometer Light Proximity Microphone Camera NFC/RFID Touch user interaction Can run custom applications Can utilize IP network technology

6. History Xerox Tab (1992) Linus Write-Top (1987) Apple Newton (1993) Nokia 7110 (1999) Apple iPhone (2007) Palm 1000 (1996) Microsoft Pocket PC (2000) Windows Mobile (2002) HTC Dream Android (2008) HTC Windows Phone 7 (2010) Sony Ericsson R380 (2000)

7. Weaknesses Limited power supply (typically max 24 hours) Limited processing power Limited programming API’s Hard to extent with new sensors Dependent on device manufacturers OS Often limited application control Not suitable for all users types Not necessarily “calm technology” Easy to forget at home Easy to forget to recharge

8. Main platforms iOS Android Symbian RIM Windows Phone 7 Other

9. Development tools iOS Xcode (Objective C) MonoTouch (C#) Android Eclipse (Java) Visual Studio (Mono/C#) Windows Phone 7 Visual Studio (C#)
