1. David Kim 396 Devin Galutira 396 Calvin Choy 396 Audio Feedback Handwriting Accessor

2. Problem Statement  Writing is easy for non blind people  Visual cues to aid in forming characters  Blind people have no or limited writing capability due to lack of sight  Signatures often done with a mark or x  If we can teach a blind person to write...  Then they can gain independence in the community, workplace & educational settings

3. Approach  To train blind people to use Audio feedback as a substitute for visual feedback.  To develop one’s motor skills and muscle memory through Audio feedback & training.

4. Overview of Project  Create A Handwriting Device with Audio Feedback  Device Equipped with Stylus  Sensors – Accelerometers  Audio output  Microprocessor  DSP  Sound Synthesizer  Power supply

5. Overview (cont)  Mobile  Device should be small and portable  Easy to set up and use in different places  User friendly  To produce a continuous audio feedback  Intuitive feedback to user  To experiment and discover the optimal set of sounds that is pleasant to the user.  Training Tools  Character stencils to guide motion and provide haptic feedback

6. Potential Obstacles  Real time processing of accelerometer data  Programming difficulties  Producing continuous audio output that is useful to the user  Hardware size limitations  Placement of Accelerometer for accurate data

7. Learning Expectations  Learn Useful application of accelerometers, dsps, and sound synthesizer.  Create a system of all the components working together.  To find a good approach to teaching a blind person to use our device.  Enhance knowledge in BASIC

8. Goals  Working device that is of reasonable size  Intuitive, easy to interpret audio feedback that will develop muscle memory  Stencils that provide useful haptic feedback
