3SKINPUT TECHNOLOGY

It turns the body into Touch Screen Interface.

Developed By Chris Harrison, Desney Tan And Dan Morris of the Microsoft Research’s Computational User Experiences Group.

It is a Technology That Appropriates The Human Body For Acoustic Transmission.

Introduction

4SKINPUT TECHNOLOGY

Project Is Under Active Development And Is Not Available Commercially.

(Contd…..)

5SKINPUT TECHNOLOGY

Its First Public Appearance Was At Microsoft's Techfest 2010

6SKINPUT TECHNOLOGY

TOUCH SCREEN(Physical Interface

needed)

Difference B/W Touch Screen And Skinput

SKINPUT(No Physical

Interface Required)7SKINPUT TECHNOLOGY

Allows User To Tap Their skin To Control Audio Device, Make Call , Play Game And For Navigation Purposes.

Uses Series Of Sensors To Determine Tapped Location.

Detects Waves Produced Due To Finger Tap To Perform Action

What Skinput Technology ?

8SKINPUT TECHNOLOGY

Each Part Of The Body Creates Different Types Of Variation Depending On The Features Of Bones And Muscles.

Skinput Listens To These Variations To Determine Tapped Location.

(Contd…..)

9SKINPUT TECHNOLOGY

WHAT MAKES IT WORK ?

Bioacoustics

Pico Projector

Bluetooth

10SKINPUT TECHNOLOGY

A very small projector basically used in gadgets.

E.g. Spice Popcorn (Mobile cum Projector)

How Skinput Works ?Pico-Projector

11SKINPUT TECHNOLOGY

Study Of Sound Waves Inside Human Body.

When Finger Taps Following Waves Are Produced

A. Longitudinal WavesB. Transverse Waves

These Waves Serves Input For The System .

(Contd…)Bioacoustic

12SKINPUT TECHNOLOGY

Bio-Acoustic

13SKINPUT TECHNOLOGY

Bio-Acousting : SensingThese signals need to be sensed and worked upon

This is done by wearing the wave sensor Armband

14SKINPUT TECHNOLOGY

PROCESSING : ModelAn audio interface is captured from sensors and is converted to

digital signal form

This is connected to a pc system via

Bluetooth

A software to match sound

frequencies to specific skin

location is used.

Corresponding implemented to

system 15SKINPUT TECHNOLOGY

Input Locations Fingers (5 Locations)

Whole Arm(5 Locations)

Forearm (10 Location)

To Maximize the Surface Area For Input , We Placed The Sensor Above The Elbow Leaving the Forearm Free.

16SKINPUT TECHNOLOGY

Accuracy

17SKINPUT TECHNOLOGY

Applications

Mobile

Gaming

I-pods

Simpler Browsing Systems.

An aid to paralyzed people

18SKINPUT TECHNOLOGY

Advantages No Need To interact with the Gadget directly .

Skinput Will Bring a New Way Of Operating a Mobile Phone By Turning a Persons Hand Into a Keyboard And Forearm Into a Screen

People With Larger Finger Get Trouble in Navigating Tiny Buttons On Mobile Phones . With Skinput That Problem Disappears.

19SKINPUT TECHNOLOGY

Disadvantages

20SKINPUT TECHNOLOGY

Accuracy Can Degrade Over Time The Longer You Wear It.

Technology Might Start Up At Very High Cost Which Can Not Be Affordable For The Common Man.

21SKINPUT TECHNOLOGY

Research is Carried For smaller Wrist Watch Sized Sensor Armband

Conclusion

22SKINPUT TECHNOLOGY

System Perform 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 But Its Fate Will Ultimately Depend On How Committed Microsoft Is To Make It A Commercial Reality And How Soon.
