T he iDOCENT Phase II is a continuation of an indoor navigational smartphone application system for the Michigan State University Resource Center for Persons with Disabilities. The main purpose of iDocent is to guide the visually impaired, visitors, and emergency personnel inside campus buildings. iDOCENT Phase I made use of existing Wi-Fi access points to triangulate location of an individual. Phase II system utilizes microphone modules to receive a sound signal from a smartphone speaker. Microphone units are connected to the server via existing Ethernet network. Ethernet provides fast communication between modules and the server and supplies power to each microphone unit. The system command prompts are voice or touch activated, depending on user preferences and abilities. Once the user opens the application, the correct map structure is automatically downloaded. The application will then establish communication with the server. The server registers each user based on their phone number. After conﬁrmation, a high frequency audio signal will be sent through the smartphone speaker. Microphone modules will receive the signal and pass it to the server. This signal will be received by the three closest microphones in the area. The microphones will individually encode a time stamp when the signal is received and forward to the server. Based on collected data, the server will triangulate the current location of the user. The application will also enable users to select points of interest, such as emergency exits, and efﬁciently navigate the user to that location. http://www.egr.msu.edu/classes/ece480/capstone/fall11/group02 Project Sponsors Marathon Oil Corp and MSU Resource Center for Persons with Disabilities Sponsor Representative Mr. Stephen Blosser Faculty Facilitator Dr. John Deller Team Members & Non-Technical Roles Kirk Guotova Manager Adam Partlo Webmaster Vadim Kim Documentation Prep Shreyas Thiagarajasubramanian Presentation Prep Mr. Blosser Dr. Deller PAGE 33 K.

The iDOCENT Phase II is a continuation of an indoor navigational smartphone application system for the Michigan State University Resource Center for Persons with Disabilities. The main purpose of

iDocent is to guide the visually impaired, visitors, and emergency personnel inside campus buildings. iDOCENT Phase I made use of existing Wi-Fi access points to triangulate location of an individual. Phase II system utilizes microphone modules to receive a sound signal from a smartphone speaker. Microphone units are connected to the server via existing Ethernet network. Ethernet provides fast communication between modules and the server and supplies power to each microphone unit. The system command prompts are voice or touch activated, depending on user preferences and abilities. Once the user opens the application, the correct map structure is automatically downloaded. The application will then establish communication with the server. The server registers each user based on their phone number. After confirmation, a high frequency audio signal will be sent through the smartphone speaker. Microphone modules will receive the signal and pass it to the server. This signal will be received by the three closest microphones in the area. The microphones will individually encode a time stamp when the signal is received and forward to the server. Based on collected data, the server will triangulate the current location of the user. The application will also enable users to select points of interest, such as emergency exits, and efficiently navigate the user to that location.
