P07002: Project Background
• Currently deaf students use two methods of communication during office hours with professors or meetings with tutors
– Hand-written (20-30 words per minute)*
– Typing conversation (40-60 words per minute)*

P07002: Risk Assessment
• Risk: Software– Need cross-platform programming language
• Solution: Use C++ along with QT design environment to develop GUI
– Saving conversations in format that is cross-platform• Solution: Use .pdf file format to store conversations
• Risk: Components– Is memory and storage adequate for device?
• Solution: Benchmark Linux specs on PC in lab to determine proper amount needed - 256Mb RAM, 1Gb Flash Memory

P07002: Risk Assessment
• Risk: Heat Dissipation– What is the required air circulation for the
device?• Solution: Experiments and analysis of device
components need air circulation of 1.205 ft3/min
• Risk: Power Supply– Internal power supply will result with large
case design• Solution: Must find external power supply that can
provide 5V/12V @ 10A

P07002: Current State of Design
• Software being developed
• Solidworks being used to model case design
• All components besides casing materials ordered– Only long lead item is LCD screen
(ETA 12/10/2006)

P07002: Current State of Design
• Test plan developed to ensure specs are met once design is complete
• Spent $979.00 of budget which leaves $221.00 for casing materials
• Design meets all engineering specs and customer needs except:– Internal power supply increases dimensions of casing
2.5in x 7in x 9.43in
