5. G OALS 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. Presenter: Jenny Cofer Capstone Senior Design 2012 COMIT TouchSystems 4

6. G OALS Possible extension: Implement kinesthetic learning through objects that the table recognizes Incorporate lessons in the fields of geography, language, history, health, or other categories. Presenter: Jenny Cofer Capstone Senior Design 2012 COMIT TouchSystems 5
