PHASE IV
Project Goal:
To create a PC keyboard that would enrich text communication with expression via typing force
Phase IV Eliminated the “ghosting” and sample time issues experienced by Phase III. Final physical and electrical modifications were made to provide a “finished” product to NTID. Additional testing was done in order to characterize opportunities for enhanced data.
Design
Results Entire electrical and mechanical package was upgraded to provide error free data. The aesthetics of the DK now meet spec. Successfully data was captured by team and customer testing protocols are under IRB review.

Phase III Created the final prototype by modifying an existing off-the-shelf keyboard, implementing force feedback via LEDs on the keyboard, and optimizing the force sensors’ location with a new custom made PCB.

Final Phase - Phase V (eta 2012) Create a software application that would use the Dynamic Keyboard force outputs to enrich text with expression.
Phase II Created the initial prototype by modifying an existing keyboard and using a custom made PCB with pressure sensors under the keys.
