Design of AirFlipTwo variations:Just flipping the thumb(fig 1), used as a button.
Twirling the thumb(fig 2&3), used such as a rotational angle of a map.IP Lab, IPS, Waseda Univ.

ImplementationAirFlip is an Android application that monitors hover events CURRENTLY.
AirFlip is recognized when hover events begin to appear and then disappear quickly(600ms)IP Lab, IPS, Waseda Univ.
6Slide7
ImplementationThere are two problems, AirFlip is incorrectly recognized in naïve implementation for the following two reasons.
1. AirFlip is recognized when users tap the screen, hover event occur before and after a tap.2. AirFlip is recognized when users are searching for a target to touch, their thumb tends to enter and leave the top boundary of the hover zone frequently in this context.

7Slide8
ImplementationSolutions To address problem 1,
AirFlip is ignored when a touch event occurs within 50ms after hover eventsdisappear.To address problem 2, AirFlip is ignored when their thumb leaves the hover zone more than 600ms after their thumb has entered it.

EvaluationIP Lab, IPS, Waseda Univ.
10Participants: 8 males and 4 females aged from 20 to 25(mean=22.7, SD=1.29)Apparatus: a mobile device(ELUGA P P-03, OS: Android 4.2.2) with an approximately 4.7 inch touchscreen.
Methods: compared the performance of the three methods for switching tabs: AirFlip, Bezel Swipe, and Touch.Procedure: ask the participants to perform this user study as accurately and rapidly as possible.Slide11

Discussion & ConclusionIP Lab, IPS, Waseda Univ.
13While we found much incorrect recognition lowered the performance of AirFlip
in the evaluation, we considered that two factors of this problem can be addressed to improve the performance.1. Accidental touching, users often touched the touchscreen accidentally while performing
AirFlip.This problem maybe caused by hover zone being too narrow. Maybe to improved the sensing capability can solve the problemSlide14
Discussion & ConclusionIP Lab, IPS, Waseda Univ.
142. Incorrectly thinking users’ thumb has moved out of the hover zone.
To address this problem, we plan to provide users with feedback such as
vibration
when users move their thumb out of the hover zone.Slide15
Discussion & Conclusion

15Moreover
we plan to attach a protective case to a mobile device shown in the figure. This case is designed so that its side is higher than the surface of the device
. With this case, users will be able to use AirFlip by flipping the side of the case.Slide16
Discussion & ConclusionIP Lab, IPS, Waseda Univ.
16Future work.For
immediate future work, we plan to incorporate a haptic feedback and measure the performance of AirFlip using a protective case whose side is higher than the surface of
the device. Furthermore, we also plan to implement a mobile device with hover sensing capability that can sense user's
fingers in higher positions by using a vision-based approach.Slide17
