CAN YOU EVER IMAGINE HUMAN BODY AS A TOUCH SCREEN???

YES!!!! There is a solution And That’s SKIN PUT

CONTENTS Introduction Principle of skinput How it works Advantages Applications Future Implications Conclusion

INTRODUCTION Skinput is a technology that appropriates the human body for acoustic transmission. It was developed by Chris Harrison, Densely Tan, and Dan Morris of the Microsoft Research's Computational User Experiences Group(MRCUEG). Its first public appearance was at Microsoft's Tech Fest  2010

It uses the sensors to determine where the user taps on their skin. CONTINUATION…. Skinput allows the user to simply tap their skin in order to control audio devices, play games, make phone calls. It uses the sensors to determine where the user taps on their skin.

PRINCIPLE OF SKINPUT It listens to vibrations in your body. Skinput also responds to the various hand gestures. The arm is an instrument. Arm band  detects the acoustic signals and convert them to electronic signals which easily enable the users to perform simple tasks as browsing through a mobile phone menu, making calls, controlling portable music players, etc..

TECHNOLOGY USED Skinput, the system is a combination of two technologies: the ability to detect the ultra low frequency sound the ‘Pico’ projectors. Pico projector applies the use of projector in a hand held device. An acoustic detector detects the ultra low frequency.

PICO-PROJECTOR A very small projector, basically used in gadgets. The system comprises three main parts: The Laser light source The Combiner optics The Scanning mirror

HOW IT WORKS In Skinput, a keyboard, menu, or other graphics are beamed onto a user's palm and forearm from a pico projector embedded in an armband. An acoustic detector in the armband then determines which part of the display is activated by the user's touch. Their software matches sound frequencies to specific skin locations, allowing the system to determine which “skin button” the user pressed.

Projector display image on arm Finger tap on arm vibrations produced and passed through bones onto skin Electronic signals produced in the form of music then detected by detector in armband

USER RESEARCH: SKINPUT Playing Tetris: Using Fingers as Control Pad Active also in Movable Environment Using Fingers, Palms, Arms as Control Any Computing Device Can be run .Response is real time, robust & remains functional while walking & Accuracy level is 99.5%()

ADVANTAGES No need to interact with the gadget directly. Don’t have to worry about keypad. People with larger fingers get trouble in navigating tiny buttons and keypads on mobile phones. With skinput this problem disappears. The body is portable and always available, and fingers are a natural input device.

disadvantages Though the band seems easy enough to slip on, many people would not wear a very big band around their arm for the day. Not enough research has been conducted on this product to test the possible skin diseases or types of cancer, one can get from using this product. This technology might start up at very high cost which will not be affordable for the common man.

APPLICATIONS Mobile Gaming I-pods An aid to paralyzed persons.

SKINPUT IN FUTURE The most profound achievement of Skinput is proving that the human body can be used as a sensor. A person might walk toward their home, tap their palm to unlock the door and then tap some virtual buttons on their arms to turn on the TV and start flipping through channels. Extensive Research is going on Currently on Skinput to make the armband more smaller. Incorporate More Devices with This System. Extend accuracy level.

CONCLUSION Skinput allows the human body as an input surface. We conclude with descriptions of several prototype applications that demonstrate the rich design space we believe Skinput enables.
