1. CMPS 261 – Project Proposal Visually Representing American Sign Language Translations Victor Geislinger

2. Background/Motivation ● American Sign Language (ASL) ● Fingerspelling (FS) ● Handshapes – Basis of language

3. Background/Motivation ● Interpreters – Emergency – Inaccessible – Expensive ● Learning Tool – Feedback

4. Method ● Collect Data via Leap Motion Controller – Focus on hand(s)/finger(s) – Real time capture http://reviews.cnet.com/input-devices/leap-motion-controller/4505-3133_7-35823002.html

5. Method ● Categorize individual letters – Form hard to determine ● Classify group shapes – Easier to guess – “Autocorrect” feature

6. Method ● Transitions sometimes exist as one unit – “J” and “Z” – Double letters – “I-L-Y” – “A-I-R” – “B-U-S”

7. Output ● Gives interpreted word/sentence ● Color coded to give likely letter from shape group

8. Output ● Features other possible guesses – Given by opacity, position, and/or hierarchy tree ● Gives timeline of duration of letter – Possibly used to visually see speed of speech

9. Potential Issues/Challenges ● Identifying letters from same group – Difficult/impossible to do with current technology ● Differences in style/accent ● Transition lengths ● Output might have to many possibilities
