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: 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

P07002: Project Needs and Specs

• Customer needs and engineering specs:– Portable Size < 2in x 10in x12in

Weight < 12 lbs– Easy to use Less than 15 min. training

required– Easy to update 4 steps or less to update

database– Design within budget $1200– Need for efficient and fast Include database of method of

communication commonly used phrases

P07002: Design Concept - Software

Student: Hi Dr. DeBartolo

Teacher: Hi Aisosa, what’s up?

I have a question on the homework

question on the lecture notes

question on this equation

reason to miss the next class

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


8

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: 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

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)


11

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


12

P07002: MSD II Project Schedule Milestones

• Dec 15: Case design finalized and parts ordered

• Jan 8: Start build of case• Jan 12: Software development completed

(GUI, database, search method)• Jan 15: Debug, troubleshoot and test device• Jan 29: Pilot device with NTID students• Jan 29: Write user manual, start project

documentation
