1. Multi-Touch Navigation Engine Presented By: Chris Jones Shuopeng Yuan Nathan Wiedeback

2. Background AIS currently offers single-touch Customers have shown interest in Multi-touch

3. Project Specifications Described needRequirementsSMART Specs 1.Multi-touch programmable user input system 2 - 6 independent control channels Defined (compile-time) channel areas 2.Easily demonstrated and integrated Able to show that it worksSee more specifics below Able to combine with existing productsWritten in C

4. 3.Ensure smooth, repeatable, and accurate trackingSmoothLow response time (specify) Repeatable Test cases: poke specific coordinates several times, make sure we get the same data (within margin TBD) AccurateUse a target area (TBD) 4.Navigation Engine = electronic signal processing unit Rabbit or ARM microcontroller Recognize defined patternsAccept TBD% average-sized fingers Accept TBD% average-sized hand edges Reject TBD% average-sized palms (Test the above with many users with a range of hand sizes) Pattern navigation and interpolation Control channel assignment/arbitration Control channel processing

5. Architecture

6. Accomplishments Translate sensor wire into 16x16 matrix data Dynamically plot processed sensor data

7. Demo Design Hardware Software Compiler : Rabbit Dynamic C Demo Plotter: Matlab

8. How does it work

9. Future Work - Platform Initial design is going to take place on the Rabbit 3000 Architecture. In the future we are likely going to shift to ARM platform.
