Phone OS, Google’s Android, Symbian OS, RIM’s Black. Berry, Palm’s Web. OS, 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 INTRODUCTION

Smartphone Market Penetration Smartphone Touchless Screen INTRODUCTION

Smartphone Touchless Screen OBJECTIVE

800% 50% Worldwide Smartphone Sales to End Users by Operating System in 1 Q 10 (Thousands of Units), according to Gartner Smartphone Touchless Screen BACKGROUND

2010 Q 3: 43. 6% Android Platform. . Share of 2010 Q 2 smartphone sales to end users by operating system, according to Gartner 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 Smartphone Touchless Screen BACKGROUND

Idea Smartphone Touchless Screen 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.

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