3. Introduction
AirFlip is a Double Crossing in-air gesture using boundary surfaces of hover zone for mobile diveces.
IP Lab, IPS, Waseda Univ.

4. Design of AirFlip There are 2 variations of AirFlip:
Flipping the thumb(fig 1), used such as a button.
Circling the thumb(fig 2), can be used to rotate something, e.g. rotate a map.

5. Application 1 Switching tabs in web browsers
2 Rotating a map in map applications.

6. Implementation
AirFlip is an Android application that monitors hover events CURRENTLY.
AirFlip is recognized when hover events begin to appear and then disappear quickly(600ms)

7. Evaluation
The author with 12 participants compared the performance of the three methods for switching tabs: AirFlip, Bezel Swipe, Touch. Then take a questionnaire to the 12 participants. And we can get some conclusions.

8. Evaluation Results and Analysis of the performance
The figure shows that AirFlip is nearly twice slower than the other methods

9. Evaluation Results and Analysis of the questionnaire
(5 means strongly agree and 1 means strongly disagree)
This figure shows that AirFlip is not so good, in accuracy and easiness need some improvement.

10. Evaluation From the exercise, AirFlip is not good enough.
There are some questions need to be solved just like protected case.
Future work: vibration feedback, protected case, and sensing user’s fingers in higher positions.
