6. 18-549 Team 1: Reflex Project Presentation 1/18/2007 6 Risks & Mitigation “We lost data during communication”: Disregard, or guess with ‘before & after’ “We don’t know how to talk to Wii”: Just talk to laptop (or beg Nintendo for help) “We can’t get the flex sensor to cooperate”: Use the one with pre-made board instead “Reflex is too slow & laggy”: Optimize code or limit functionality “Our sensors aren’t sensitive enough”: Hmm… (target the elderly?)
