Identify Customer Needs

Step 1. Gather Raw Data From Customers

Customer: Gary Behm

Upon the first meeting between the group and the customer, Gary Behm introduced us to the problem. During his lectures, he would find switching slides in his PowerPoint presentations very difficult and annoying as he would have to do one of the following: 1. Stop signing and use a keyboard or mouse to go to the next slide or 2. Stop signing and use the wireless remote to flip slides.

Gary tasked us to design him a system that would allow him to flip slides while still retaining the ability to keep signing and walking around. This system, he said, should be small, lightweight, something non intrusive. It has to be durable and workout through a whole class before it will need recharging (if a battery is used.) It must not interfere with any other devices in the classroom and must work in such a range that he can give a presentation in an auditorium. The system should be void of any false triggers and must interface with a PC.
