Technology Transfer:Haptic Feedback

Explain technology transfer and technological innovation.

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?

low frequency (left motor)high frequency (right

motor)

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

Notice how different kinds of controls have different kinds of

inputsInput Device

Digital Buttons

Analog Control

Keyboard >100 0 No Yes Yes 1

Mouse 5 3 No Yes No 1

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.

Fine tuned Remote control

What are other examples of the

transfer of haptic feedback technology to

other technologies?

Haptic Devices• These are all manipulator gloves that give

the user feedback depending on what they are touching virtually.

Cyber Glove II Cyber Grasp Cyber Force

Haptic Devices• Space Interface Device for Artificial

Reality (SPIDAR)

SPIDAR-8. Rubik’s Cube SPIDAR-8. Finger attachments.

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.

Touchable Online Braille Generator Screen

Now they’re working on screens where you can actually feel the bumps.

Expensive Touchable Graphic

These are made of small metal cylinders that the computer controls to move up or down to create a touch image.

The Guide Cane•(Ulrich and Borenstein, 2001)

Haptics for Handicapped

This cane moves away from obstacles to guide a blind person automatically using its sensors

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

Where will it all lead?

Another future technology idea

waves to control programs or machines.
