MOBILE DEVICE AND INTELLIGENT DISPLAY INTERACTION VIA SCALE-INVARIANT IMAGE FEATURE MATCHING
Leigh Herbert, Nick E. Pears, Dan Jackson, Patrick L. Olivier · 2011
human-computer interaction, direct touch interaction, mobile device. We present further developments of our system that allows direction interaction between a camera-equipped hand-held device and a remote display. The essence of this system is the ability to estimate a planar projectivity between the remote display and the displayed image of that display on the handheld device. We describe how to achieve this by matching scale invariant SURF features across the two displays (remote and hand-held). We implement a prototype system and a drawing application and conduct both performance and usability evaluations. The feedback given indicates that our system is responsive, accurate and easy to use. 1
