SKINPUT TECHNOLOGY



Touch screens may be popular both in science fiction and real life as the symbol of next-gen technology, but an innovation called Skinput suggests the true interface of the future might be us “Skinput” turns body into touch screen interface. The founders of this great technology  is Microsoft and Carnegie Mellon University. By the way, what do skinput technology mean?....

  •          Skinput is a technology that appropriates human body for acoustic transmission, enabling the skin to be utilized as an input surface.
  •          This technology allows human hand and arm as touch screens, by sensing various low-frequency vibrations and sounds that are generated by touching different part of the hand or arm.
  •          These signals are sensed using various sensors worn on the arm in the form of arm band.

"The arm band is a crude prototype, the next generation could be made considerably smaller – likely easily fitting into a wristwatch."

From there it's fairly simple to associate those tappable areas with different commands in an interface, just as different keystrokes and mouse clicks  perform different functions on a computer.

WHAT MAKES IT WORK?

1.       PICO-PROJECTOR

2.       BIO-ACOUSTICS

3.       BLUETOOTH

 

  • 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.

WORK FLOW:

1.       Projector display image on arm.

2.       Finger tap on arm.

3.       Vibrations produced and passed through bones onto skin.

4.       Detected by detector  in armband.

5.       Electronic signals produces in the form of music.



IMPLEMENTATION OF SKINPUT:

        PARALYZED OR PHYSICALLY DISABLED PERSON: This feature provides a projected graphical interface on the skin, so the person who is paralyzed or disabled they can use it easily like making a call, playing game etc.

 

2.       EDUCATION: We can implement in education system like we can use calculator or browsing through a mobile phone.

 

3.       FINGERS AS CONTROL PAD OF GAME: Through skinput, we can play games with just the movement of our hands. This will introduce a totally new era of gaming.

 

4.       PHONECALL USING SKINPUT: It will be possible to make calls by just typing numbers that flash on your forearm. We can also increase or decrease the volume or change the track of the music players like i-pod without actually touching the gadget.

 

PROS:

·         Easy to access when your phone is not available.

·         Allows users to interact more personally with their device.

·         Larger buttons to reduce the risk of pressing the wrong buttons.

·         Through the use of a sense called proprioception after user learns where the locations are on the skin they will no longer have to look down to use Skinput reducing people looking down at their phone while driving.

·         It can be used for a more interactive gaming experience.

 

CONS:

  • \  Currently there are only five buttons. A phone uses at least 10 buttons to dial a phone number of send a text message.
  •         The easy accessibility will cause people to be more socially distracted.
  •          If the user has more than a 30% Body Mass Index Skinput is reduced to 80% accuracy.
  •          The visibility of the projection of the buttons on the skin can be reduced if the user has a tattoo located on their arm.

 

CONCLUSION:

Skinput could relay tapped commands to mobile devices or PCs via wireless technologies like Bluetooth. If this gadget ever becomes a commercial reality, it could redefine our perception of common gestures. Drumming our fingers nervously could actually be texting, for example,

while a slap to the forehead could launch a web browser. Extrapolating from the arm device, skinput could turn the whole body into one giant quivering, jumping, dancing interface. Also, with the addition of a Pico-projector to the armband, skinput could allow users to interact with a graphical user interface displayed directly on the skin make it more convenient and easier.

MULTIMEDIA

  These days, most of us carry a fully functional multimedia studio around in our smartphones says Austin Kleon . We people  really wanted to engage with our own generation, one that is increasingly speaking in an audio/video multimedia language.  Multimedia is an effective way to communicate and share the ideas with users. W hat is multimedia??.... In what ways are they used ??.. Well, The proper definition of multimedi a is a computerized method of presenting information combining text, audio, video, graphics and animation . As the name suggests it is the combination of multi and media that different types of hardware and software tools  are used for communication of information. Let us see some examples related to multimedia from the bricks to the brains; ·         The text we see in books, newspapers or any means of media ·         The sound we hear when we listen to music ·         The graphics we see in science fiction movies ·         Ads placed in newspapers by busi

Exploring The Hidden Internet

What is the internet to us? Facebook, Instagram, Twitter, Youtube, Amazon, Flipkart, and many more websites, That's it? Well, no! The most fascinating and shocking fact is that the internet we use each day is just 4%. In this article, we are going to learn about the mysterious side of the internet.  Curious? Let's head on to our topic. Introduction The Internet is a vast network that connects all the computers across the globe which enables people to share information as well. The internet pieces of information are broadly classified into three types : Surface Web Deep Web Dark Web Surface VS Deep VS Dark Web Let's imagine the internet like a glacier. As we know the visible part of the glacier is small but the non-visible parts of the glacier under it are too deep. SURFACE WEB: The surface Web is often compared to the top of the glacier which is small, visible, and can be accessed easily. In other words, the Surface Web is simply the internet we use in our daily life. The s
