COMIT TouchSystems1

OVERVIEW• This project will provide a table-sized multi-touch interface on

which to run educational applications. • Primary Focus:

• Exciting and dynamic to promote user engagement

• Non-conventional learning experience

We intend to use exciting visual stimuli, touch, sound, and kinsesthetics to teach the users in a meaningful way.

MOTIVATION…


COMIT TouchSystems3

GOALS• Baseline:• Multi-touch table interface to be used by multiple users

• Provide educational applications that address learning in creative ways

• Visual learning through the display

• Auditory learning through speakers

• Incorporate lessons in the fields of math, music, and science.


COMIT TouchSystems4

GOALS• Possible extension:

• Implement kinesthetic learning through objects that the table recognizes

• Incorporate lessons in the fields of geography, language, history, health, or other categories.
