Sensory Mapping Client: Miroslav Backonja Advisor: Mitch Tyler Team Members Colleen Farrell (BSAC) Adam Pala (BWIG) Jeremy Schaefer (Team Leader) Steve Wyche (Communicator) Function: The purpose of this project is to design a systematic method to accurately measure the surface area of sensory abnormalities. Client Requirements: 1) Should give quantitative results 2) Should be able to measure contoured areas of the body 3) Results should be reproducible Design Requirements: 1. Physical and Operational Characteristics a. Performance Requirements: Measure more accurately than the current tracing method. Must function over all surfaces of the body b. Safety: Must have minimal skin contact due to patient sensitivities. c. Accuracy and Reliability: Accurate within 5-10% of actual surface area. Results should be reproducible. The cameras to be used can measure distances with an accuracy of less than one millimeter d. Life in Service: Device should last through the duration of the clinical trials e. Shelf Life: Indefinite, since the final product will not likely include disposable parts or perishable materials. Batteries in LED penlight will need to be replaced when they die f. Operating Environment: Function at room temperature g. Ergonomics: Must be comfortable and convenient for doctor useh. Size: No strict guidelines. Small enough for in clinical use and to allow easy portability i. Weight: The pen with infrared LED will weigh less than a pound j. Materials: Infrared motion capture equipment. Including: three infrared cameras, infrared LED pen, ground plane, USB cables, synchronization cables k. Aesthetics: Due to use in clinical testing, aesthetics are not of utmost concern 2. Production Characteristics a. Quantity: one working prototype b. Target Product Cost: $500-$1000 for working prototype 3. Miscellaneous a. Standards and Specifications: The prototype will be compared to the current tracing method that is being employed b. Patient-Related Concerns: Minimal skin contact c. Competition: Zcorp Zscanner
