Temperature Feedback in Devices

Computer peripherals and other devices, such as touch pads, rely on visual feedback to indicate the location of a stylus or finger, or an artifact such as an image or drawing.

For the seeing impaired, as well as sighted people, this can make touch-based devices very difficult to use.

This invention uses heat generating nodes to translate visual data into sensory data within the device.

Use cases where temperatures can be beneficial:

• Navigation

• Buttons

• Maps

• Popularity - items on the view with a higher popularity can have a hotter feel

• Gaming


1. A new touch sensitive device is manufactured with heat spotting/cooling technology. This can be done through hardware configurations such as low conductivity metals, water cooling systems, fans, etc.

2. An application developer creates an application in which they would like to utilize the heat sensitive aspects of this invention. Applications can include:

A. Native applications with native application specific attributes

B. Web based applications with hypertext markup language (HTML). A new html heat tag can be applied (e.g., )

3. Optionally, the user can set system-wide preferences for heat technology

A. All attributes with a given type ex. All buttons should feel hotter to the touch then the rest of the screen

B. Turn off for all

C. Set temperature preferences (how much is enough for the user to feel the difference)

D. Turn off after inactive for 5 secon...
