Smartphone Touchless Screen
Outline
Smartphone vs Average Cell phone
• Calling vs Email, Internet, Digital Camera, Navigation Possibilities
• Smartphones Have a Mobile Operating System, Full Qwerty Keyboard
(Hardware or Software), Synchronize with email server, view and
sometimes edit documents..
• Windows Mobile, iPhone OS, Google’s Android, Symbian OS,
RIM’s BlackBerry, Palm’s WebOS, Linux
• IBM designed the first smartphone in 1992 (Simon)
• Motorola demonstrated the first cell phone, 19 years before the first
smartphone, in 1973.

Smartphone Touchless Screen
Background
• Android
• Mobile operating system developed by Android Inc;
• Based upon a modified version of the Linux kernel;
• A corresponding open-source project led by Google;
• Android has been available under a free software / open source
license since 21 October 2008;
• Google published the entire source code under an Apache
License (vendors can add proprietary extensions without
submitting those back to the open source community ).
No industry player can control or restrict innovations

Orientation Based Touchless Screen
Approach
Android Orientation System:
- Origin in bottom left
- z = Azimuth, rotation around
the Z axis (0<=azimuth<360)
- x = Pitch, rotation around X
axis (-180<=pitch<=180)
- y = Roll, rotation around Y
axis (-90<=roll<=90)
All angles are in degrees.

Smartphone Touchless Screen
Magnetic Field Based Touchless Screen
Approach
Android Magnetic Field System:
- Origin in bottom left
All values are in micro-Tesla (uT)
and measure the ambient
magnetic field in the X, Y and Z
axis

Magnetic Field Based Touchless Screen
• The magnetic field might affect the compass
hardware
• The magnetic field might have an effect on the
storage memory of the smartphone
• The app works better when the magnetic field is
clearer (long enough magnet)
• Paradoxes: magnet vs smartphone…
Smartphone Touchless Screen
Challenges
• Two Android apps have been developed to implement
the two proposed touchless screen ideas
• Orientation based Touchless Screen
• Magnetic Field based Touchless Screen
• The two apps have been loaded into a real smartphone
(HTC Legend) and work fine.
• The effect of gravity and the effect of wind…
Smartphone Touchless Screen
Conclusion
• Scrolling of the object (Window, List, Grid…) which
has the focus;
• Find a way to make the app work with a very small
magnet...
• Other Alternatives of touchless Screen (Bluetooth:
More accurate than the magnet, Voice Recognition,
Gesture Recognition)
