Skinput is a technology developed by Microsoft researchers that uses sensors in an armband to detect vibrations on the skin in order to use the human body as an input device. It works by listening to acoustic signals produced from taps and gestures on the skin. The armband detects these low frequency sounds and converts them to electronic signals that can be used to control devices like phones and music players. While the technology has applications helping disabled users, challenges include the armband needing to be smaller and more comfortable to wear long-term as well as further research on potential health effects.

3. INTRODUCTION:
 SKINPUT I S A TECHNOLOGY WHICH USES THE S UR FACE OF THE SKI N
AS AN INPUT DEVICE.
 TO CAPTURE T H I S ACOUSTIC INFORMATION , T HEY DEVEL OPED A
WEAR ABLE ARMBAND THAT I S NON-INVASIVE AND E A S I LY REMOVABLE.
 I T WAS DEVELOPED BY CHRIS HARRISON, DENSELY TAN, AND DAN
MORRIS OF THE MICROSOFT RESEARC H ' S COMPUTATIONAL USER
EXPERIENCES GROUP(MRCUEG)
 I T USES THE SENSORS TO DETERMINE WHERE THE USER TAPS ON T H E I R
S K I N .
 I T S F I R S T PUBLIC APPEARANCE WAS AT MICROSOFT'S TECH FEST
2010

4. PRINCIPLE OF SKINPUT:
 I T L I S T E N S TO VIBRATIONS I N YOUR BODY.
 SKINPUT ALSO R ES PONDS T O T HE VAR IOUS HAND GESTURES.
 THE ARM I S AN INSTRUMENT.
ARMBAND 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 MUSICPLAYERS, ETC..
 T HE ABI L I T Y T O DET ECT T HE UL T R A 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.

5. HOW MAKE IT WORKS:

6. PICO PROJECTOR
  A ver y small projector, basically it
Is used in gadgets
 The system comprises three main parts:
 The Laser light source
 The Combiner optics
 The Scanning mirror

7. BIO-ACOUSTICS
 STUDY OF SOUND WAVES INSIDE L I V I N G BODY.
 WHEN A F INGE R TAPS THE S K I N , SEVERAL DI S T I NCT F OR MS OF
ACOUSTIC ENERGY A RE PRODUCED.
 LO N G I T U D I N A L WAVES
 TRANSVERSE WAVES

8. HIGHER ACCURACIES CAN BE ACHIEVED BY COLLAPSING THE 10 INPUT LOCATIONS INTO
GROUPS. A–E AND G WERE DESIGNED TO BE SPATIALLY INTUITIVE. F WAS CREATED
FOLLOWING ANALYSIS OF PER-LOCATION ACCURACY DATA.
The three input location sets evaluated in the
study.

9. IMPLEMENTATION:
• IMPLEMENTATION ON PARALYZED
PERSON OR PHYSICALLY DISABLE
PERSON.
• IMPLEMENTAION IN EDUCATION
SYSTEM
• USING FINGERS AS CONTROL PAD OF
GAME
• MAKING A PHONE CALL USING SKINPUT
• CONTROLLING MUSIC PLAYER
APPLICATIONS USING SKINPUT

10. ADVANTAGE:
• DON’T HAVE TO WORRY ABOUT KEYPAD.
• PEOPLE WITH LARGER FINGERS GET TROUBLE IN NAVIGATING TINY
BUTTONS AND KEYPADS ON MOBILE PHONES. WITH SKINPUT T H IS
PROBLEM DISAPPEARS.
• NO NEED TO INTERACT WITH THE GADGETS DIRECTLY

11. DISADVANTAGE:
• THOUGH THE BAND SEEMS EASY ENOUGH TO S L I P ON, MANY
PEOPLE WOULD NOT WEAR A VERY BIG BAND AROUND THEIR
ARM FOR THE DAY.
• NOT ENOUGH RESEARCH HAS BEEN CONDUCTED ON T H I S
PRODUCT TO TEST THE POSSIBLE SKIN DISEASES OR TYPES
OF CANCER, ONE CAN GET FROM USING THIS PRODUCT.
• THIS PRODUCT MIGHT START AT HIGH COST SO MANY OF
THEM CAN’T AFFORD IT

12. DISADVANTAGE:
THE MOST PROFOUND ACHIEVEMENT OF SKINPUT I S PROVING THAT THE
HUMANBODY CAN BE USED AS A SENSOR.
EXTENSIVE RESEARCH I S GOING ON CURRENTLY ON SKINPUT TO
MAKE THE ARMBAND MORE SMALLER.
 I NCORPORATEMORE DEVICES SYSTEM.
 EXTENDACCURACY L E V E L .

13. CONCLUSION:
• SKINPUT ALLOWS THE HUMAN BODY AS AN INPUT SURFACE.
• THI S SYSTEM PERF ORMS WELL EVEN WHEN THE BODY I S IN
MOTION.
• I T DESCRI BES A NOVEL, WEARABLE BIO- ACOUST I C SENSI NG
ARR AY T HAT WE B U I LT INTO AN ARMBANDIN ORDER TO
DETEC T AND LOCALIZE FINGERTAPS ON HAND AND FOREARM.
