1. EPICS Design Review Greater Lafayette Special Services Team Handheld Educational Augmentative RFID Device 2. Team Introduction Richard Wei Computer Science, Sophomore Design Lead Kristen Kummen Electrical Engineering, Sophomore Project Partner Liason Frank Oh Electrical Engineering, Sophomore Project Archivist Amy LoBue First Year Engineering, Freshman Financial Officer Design Review ~ Fall 2014 EPICS ~ GLASS ~ HEARD Team Members Project Partner Professor Wendt Department of Educational Studies and Department of Speech, Language and Hearing Sciences 3. Our Goal Design Review ~ Fall 2014 EPICS ~ GLASS ~ HEARD 3 4. Project Introduction Users are those with: Severe form of autism Motor control issues Limited or no vocabulary Currently the most common form of communication system implemented in schools Design Review ~ Fall 2014 EPICS ~ GLASS ~ HEARD 4 PECS: Picture Exchange Communication System 5. Project Introduction Goals Give children with different speaker an alternate way to learn Encourages speech production Increases independence Used to initiate communication and teach concept of asking/receiving objects Begins with single-picture communication and develops into vocal communication Demo with Key card Verbal communication production Design Review ~ Fall 2014 EPICS ~ GLASS ~ HEARD 5 PECS: Picture Exchange Communication System 6. PROTOTYPE DEMO 7. Our Demo/Prototype Design Review ~ Fall 2014 EPICS ~ GLASS ~ HEARD 7 8. Project Function Criteria Ability to bring to classroom and test with students Full functionality of recording, playback, pushbutton and RFID Touch-sensitive button under Velcro; pressure-prompted playback Lightweight, easy to handle and portable Clean surface for client; 1 button as opposed to multiple Securing agent for device on hand Organized storage for RFID keys Solution grows with the learner Possibility: sync our device with the IPAAC application / appropriate iPad application Sliding mechanics to adjust volume Safe for children; no sharp edges Design Review ~ Fall 2014 EPICS ~ GLASS ~ HEARD 8 9. Midsemester Design Review Feedback More elaboration that cards are re-recordable Specification of Battery/ Battery Life/ Requirements Has the team made from past semester. Concerns of triggers for autism with sound. The plan for creating a case. If yes, then how does it affect the budget. The budget seems not sufficient to build the device Design Review 2 ~ Fall 2013 EPICS ~ GLASS ~ HEARD 9 Concerns 10. SEMESTER PROGRESS DESIGN REVIEW 2 ~ FALL 2013 EPICS ~ GLASS ~ HEARD 10 11. Meetings with Professor Wendt Display is a distraction to clients Any buttons / display for caretaker on side of device Simplicity; client surface as clean as possible Portable / lightweight Hand Strap RFID ability to play sound multiple times; touch sensitive More pressure with button; the more action needed the better the client learns Larger key size Organize design for keys Design Review 2 ~ Fall 2013 EPICS ~ GLASS ~ HEARD 11 12. DESIGN CHANGES DESIGN REVIEW 2 ~ FALL 2013 EPICS ~ GLASS ~ HEARD 12 The reasons behind the change: It is easier to implement A click button does not require a large volume case A click button will enhance touch sensitive and sound sensitive of the device 13.

NEXT SEMESTER DOCUMENTATION DESIGN REVIEW 2 ~ FALL 2013 EPICS ~ GLASS ~ HEARD 33 How is our documentation better for next semester? Written in-depth Frank put in numerous hours Every meeting with Professor Wendt, with the team, and every lab was noted Notes taken What are we doing to make transition to next semester smooth? Three out of the four team members are staying on the team Experienced; will be able to easily explain project and status to new members 34. FDA APPROVAL DESIGN REVIEW 2 ~ FALL 2013 EPICS ~ GLASS ~ HEARD 34 The FDA is recommending that medical device manufacturers and health care facilities take steps to assure that appropriate safeguards are in place The FDA is not aware of any patient injuries or deaths associated with these incidents nor do we have any indication that any specific devices or systems in clinical use have been purposely targeted at this time. Almost all devices Professor Wendt has worked with are not FDA approved Expenses Time Necessity 35.
