Haptic Feedback
• Something you can feel– Vibration– Texture– Pressure– Response to your touch

A Problem:
Modern touch screens have no “feeling” to them. They are smooth all over. You can’t feel where to put your fingers if you can’t see.
-A lack of haptic feedback
Where will this technology come from?

Ex of Technology Transfers
1st there was the Electric motor2nd they put a motor in a rumble pack next specialized motors were added to controllers to produce different vibrations

Look inside the controller. See the 2 motors?

Technology transfer occurs when somebody applies an existing innovation developed for one purpose in a new way.
Technology transfer is a kind ofTechnological innovation often results when ideas, knowledge, or skills
are shared within a technology, among technologies, or across fields.

Many ways to get haptic feedback in video games

Digital vs. Analog
Input devices controls:– Digital
•Reports only two states: on or off•Keyboard: keys•Controller A, B, X, Y, Back, Start, D-Pad
– Analog•Report a range of values: -1.0 to 1.0•Triggers, Stick

What is an example of the transfer of video game
controller technology to other technologies?

Minimally Invasive Surgeries
Things that were learned from making better controls in video games were applied to new computer-controlled tools for doing very precise micro surgery.

Touchable Online Braille Generator
Words can be typed in ordinary English and translated into Braille.
They can be printed as bumps on a special printer.

Haptics for Handicapped
•The ActiveBelt (Tsukada and Yasumrua, 2004)Device architecture of ActiveBelt:
GPS, global positioning system; LED, light-emitting diode.
This GPS guides a person by “poking” them in the direction they should go.

Future technologies that may benefit from Technology
Transfer• SMELL
– Smell is essentially our ability to detect specific chemical particles in the air
– We can detect about 4000 different smells
– And the smells can be combined in millions different ways
