Progress Report: Digital Braille Watch Team 26 Client: Holly and Colton Albrecht [email protected] (608)239-2083 Advisor: Dennis Bahr [email protected] Team: Nick Anderson (Team Leader) Nick Thate (Communicator) Andrew Hanske (BWIG) Billy Zuleger (BSAC) WEEK 14 – April 23, 2010 - April 29, 2010 Problem Statement In order to determine the time, the visually impaired currently depend on audio or tactile analog watches. However, audible watches are disruptive, while the analog tactile watches are often difficult to read and fragile. Our goal is to develop a digital Braille watch that will efficiently display the time without the issues of the current technologies. This watch should display military time, be accurate and reliable, and utilize the standard Braille numerals. Last Week’s Goals • Finish soldering • Cut casing and assemble prototype • Write a survey to be handed out at Colton’s school • Begin to construct final poster Summary of Accomplishments • Soldering completed • Survey written and handed out • Watch code altered and finished • Prototype encased This Week’s Goals • Cut casing • Analyze testing results • Make final poster • Write final paperActivities Collaboration Group Activities Date Activity Duration 4/26/10 Final Prototype Fabrication 4 hours Team Member Date Activity Duration Nick Anderson 4/25/10 Soldering 5 hours 4/25/10 Write Survey 1.5 hours 4/26/10 Fine-tune Final Code 1 hour 4/29/10 Progress Report 30 min.
