Wise: according to user‟s explicit request or implicit intension
• Multimodal, intimacy, invisible context-aware UI
Mediated • To filter out things we do not wish to have thrust upon us
Reality against our will

38. Mobile AR
Camera for Physical Interaction
 Linking the physical to the virtual world
 The environment as part of the interface
 Camera phones as “bridging” devices
 Integration with the user’s activities

39. Mobile AR
But…
 …just switching from PC to mobile phone won’t simply solve
all current problems
 No comprehensive toolkit supporting the development of
applications based on physical mobile interactions
 New concepts and SW have to be developed that
 Make best use of the new platform
 Smaller operating system
 Weaker hardware (CPU, memory, storage)
 Take advantage of new possibilities
 Ultra mobile devices, New I/O (touchscreen, sound, vibrator, …)
 in-situ content authoring/mashup toolkit
 New UI & UX with digilog, SNS, authoring for AR eco-system
