CAN YOU EVER

IMAGINE

HUMAN BODY

YES!!!!

There is a solutionAnd

That’s

SKIN PUT

INTRODUCTION

• Skinput is a technology that appropriates the human body for acoustic transmission.

• It allows the skin to be used as an input surface.

• 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

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..

• Skinput, the system is a combination of two technologies:

1. the ability to detect the ultra low frequency sound

2. the ‘Pico’ projectors.

Pico projector applies the use of projector in a hand held device.

An acoustic detector detects the ultra low frequency.

TECHNOLOGY USED

• A very small projector, basically used in gadgets.

• The system comprises three main parts:

The Laser light source The Combiner optics The Scanning mirror

PICO- PROJECTOR

Study of sound waves inside living body.When a finger taps the skin, several distinct forms of

acoustic energy are produced.Longitudinal WavesTransverse Waves

These waves form the integral part of the whole concept of skinput.

BIO- ACOUSTICS

Longitudinal Waves:

These waves travel through the rigid tissues of the arm, exciting the waves, which can respond to the mechanical vibrations by tapping on a rigid body.

Transverse Waves:

Tapping on soft regions of the arm creates higher amplitude transverse waves.

These signals need to be sensed and worked upon.

This is done by wearing the wave sensor arm band.

BIO- ACOUSTICS: SENSING

INSIDE VIEWOUTSIDE VIEW

• 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.

HOW IT WORKS

• Currently, the acoustic detector can detect five skin locations with an accuracy of 95.5%, which corresponds to a sufficient versatility for many mobile applications.

• The prototype system then uses wireless technology like Bluetooth to transmit the commands to the device being controlled, such as a phone, iPod, or computer.

EXPERIMENT

Participants 13-> 7 female, 6 male. Ages ranged from 20 to 56. Body mass indexes (BMIs) ranged

from 20.5 (normal) to 31.9 (obese).

Each participant was made to memorize the locations for a minute .

LOCATIONS

Five Fingers

When classification was incorrect, the system believed the input to be an adjacent finger 60.5% of the time.

Ring finger constituted 63.3% percent of the misclassifications.

RESULTS

RESULTS

Whole Arm

Below elbow placed the sensors closer to the input targets than the other conditions.

The margin of error got double or tripled when eyes were closed.

RESULTS

Fore Arm

Classification accuracy for the ten-location forearm condition stood at 81.5%.

B.M.I EFFECT

High BMI is correlated with decreased accuracies.

No direct relation with gender of the participant.

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%()

USER RESEACH: SKINPUT

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.

ADVANTAGES

• 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.

DISADVANTAGES

MobileGamingI-pods• An aid to paralyzed persons.

APPLICATIONS

• 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 tomake the armband more smaller.Incorporate More Devices with This System.Extend accuracy level.

SKINPUT IN FUTURE

• Skinput allows the human body as an input surface.

• It describes a novel, wearable bio-acoustic sensing array that we built into an armband in order to detect and localize finger taps on the forearm and hand.

• We conclude with descriptions of several prototype applications that demonstrate the rich design space we believe Skinput enables.
