1. 1. THE HUMAN BODY AS TOUCH SCREEN Manoharbhai Patel Institute Of Engineering & Technology Name : Swatantra S. Gupta Roll No. : 23 Branch : Computer Technology Session : Final Year 2015/2016 Seventh Semester 2015 Guided By : Prof. A. D. Warbhe
2. 2. SKINPUT TECHNOLOGY Turns human body into a touch screen input interface.
3. 3. What is Skinput Technology? Giving input through skin It listen to vibrations in our body Skin put uses a series of sensors to track where a user taps on his arm. Provide an always available mobile input system Turns The body into a touch-screen interface. The arm is an instrument
4. 4. Screens are smaller, cameras are more ubiquitous, touch screen is everywhere. Mobility , flexibility , responsiveness are getting more demands. Microsoft puts forward a new flesh-control input technology called SKINPUT. Why this?
5. 5. Introduction Developed by Chris Harrison, Desney Tan, And Dan Morris of the Microsoft Researchs. First introduced in Microsofts Techfest 2010. Technology that appropriates the Human Body as Transmission. Project is Under Active Development, Yet Not Available Commercially.
6. 6. WHAT SKINPUT DOES ? Allows User to Tap their Skin. Uses Series of Sensor to determine Tap location. Detect Waves. Body Creates different types of variations Depending on the features of Bones and Muscles. Skinput listens to these Variation to determine Tapped location.
7. 7. WHAT MAKES IT WORKS ? Pico projector Bluetooth Bio Acoustic
8. 8. HOW SKINPUT WORKS ? Pico Projector : Small Size Projector Used for display purpose in skinput system.
9. 9. Working When User tap on skin(Hand),the Bio-Acoustics & Sensors study the sound waves. Variations in bone density, size and mass and the soft tissue and joints create Acoustically different locations When a finger taps the skin ,several distinct forms of acoustic energy are produced Transverse wave. Longitudinal wave.
10. 10. o When you tap your skin with your finger you generate transverse waves. o Tapping on soft regions of the arm create higher amplitude transverse wave than tapping on boney areas.
11. 11. Cause internal skeletal structure to vibrate. These waves travel through the soft tissues of the arm. Joints play an important role in making tapped locations acoustically distinct. This makes joints behave as acoustic filters.
12. 12. Bio - Acoustics : sensing Signal is sensed and worked upon This is done by wearing sensor armband The two sensor packages shown Each contain five, specially weighted, cantilevered piezo films, responsive to a particular frequency range.
13. 13. Armband Prototype Two arrays of five sensing elements incorporated into an armband Two sensor packages focus on the arm of input One package was located near the Radius other near the Ulna Signals transmitted though denser bones
14. 14. Processing
15. 15. Input Location Place the Sensor above the Elbow.
16. 16. Applications Mobile Gaming I-pods Simpler Browsing Systems.
17. 17. Advantages No Need to Interact with the Gadgets directly. A new way of operating a mobile phone. People with larger fingers get trouble in Navigating tiny buttons on Mobile Phones. With Skinput that problems disappear.
18. 18. Disadvantages Accuracy can degrade. High cost. Band seems easy enough to Slip on.
19. 19. Future Implications With Small sized Pico Projectors, skinput oriented systems are an Emerging trend. Research is carried out for Smaller Wrist Watch sized sensor armband.
20. 20. Conclusion System performs very well for a series of Gestures even if the body is in motion. This Approach provides an always available, Naturally portable and on body finger input system. Skinput is very interesting technology.
