Stakeholders • Individuals: • • Gary Behm – Patent Owner Patricia Iglesias – Technical Mentor Gerry Garavuso and Gary Werth – Guide The Deaf and Blind Community • Several Organizations:
Customer Requirements
Engineering Requirements
Handle allows a comfortable standard grip Lightweight Handle feedback quickly responds to obstacles Warns any object at a moderate distance in front of the user's path Warns of any object at a short distance in front of the user's path Warns of objects to the left and right sides of the user Final prototype should physically resemble a conventional cane 1 1 1 1 Recognizable to non-users as a white cane 1 Comparable cost to a conventional cane Safe to use Warns of changes in elevation Warns of uneven ground 1 1 2 2 Adjustable object-detection sensitivity Portable Easy assembly and dis-assembly Long battery life (for a day's use) Able to be used in any environment Adjustable cane length 2 2 Meet all necessary engineering standards >90% Test users agree that the haptic feedback clearly showed direction and helped guide user Maximum haptic feedback force Minimum haptic feedback force Operational Temperature Range Fully functional after 5 min exposure to rain Fully functional after 5 min exposure to snow Circuit voltage (Safety) 9 3 9 3 3 9 9 1 1 9 9 3 3 2 9 3 9 3 1 1 9 9 9 Operation of the final prototype should resemble that of a conventional cane Manufactured Product cost 9 1 1 Prototype cost Priority Detection response time Customer Requirements Handle provides directional tactile feedback to the user Weight House of Quality Matrix Disassembled length Can be disassembled in <1 min >90% Test users agree that the final product resembles a conventional cane >90% Test users agree that the cane is easy to assemble/disassemble Fully operational for >10 hours <20 minutes of “training” required for >90% of Test new users Minimum "short" distance from cane tip Maximum "change in elevation" height Cane length Minimum "moderate" distance from cane tip Engineering Requirements 9 3 9
