KGCOE Multidisciplinary Senior Design: P 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)* *Source:

KGCOE Multidisciplinary Senior Design: P P07002: Project Description Project goal is to develop device that will increase communication efficiency between deaf students, professors and tutors during office hours/tutoring sessions Market: Universities and Colleges that have a student body that encompasses deaf students Customers: Dr. DeBartolo and NTID

KGCOE Multidisciplinary Senior Design: P P07002: Project Needs and Specs Customer needs and engineering specs: –PortableSize < 2in x 10in x12in Weight < 12 lbs –Easy to useLess than 15 min. training required –Easy to update 4 steps or less to update database –Design within budget$1200 –Need for efficient and fastInclude database of method of communication commonly used phrases

KGCOE Multidisciplinary Senior Design: P P07002: Design Concept - Case USB Port LCD Screen Power Supply Keyboard Rotating Swivel LCD Screen Power Supply

KGCOE Multidisciplinary Senior Design: P P07002: Design Concept - Software Student: Hi Dr. DeBartolo Teacher: Hi Aisosa, what’s up? I have aquestion on the homework question on the lecture notes question on this equation reason to miss the next class Concentration Tab Conversation Box Text Entry Quick Keys Phrase Auto-complete Phrase Predictor Font Size Indicator

KGCOE Multidisciplinary Senior Design: P 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

KGCOE Multidisciplinary Senior Design: P 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 ft 3 /min Risk: Power Supply –Internal power supply will result with large case design Solution: Must find external power supply that can provide 10A

KGCOE Multidisciplinary Senior Design: P P07002: Device Development Process Phase 0: Meet with customer and define needs Phase 1: Concept development and selection Phase 2: Implementation planning Phase 3: Proceed with implementation Phase 4: Testing, debugging, piloting and documentation MSD 1MSD 2 Current phase of development

KGCOE Multidisciplinary Senior Design: P 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)

KGCOE Multidisciplinary Senior Design: P P07002: Current State of Design Test plan developed to ensure specs are met once design is complete Spent $ of budget which leaves $ 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
