B.3 Summary of the Responses from the Questionnaires Sensor Placement I'd like to be able to choose sensor locations if working in an office with automated lighting Although I made my best effort, I am still uncomfortable with the sensor arrangement Although I made my best effort, to place the sensors, I couldn't avoid accidentally toughing or shading them Response Totally agree 7 Partially agree 2 Neither agree nor disagree 1 Partially disagree 0 Totally disagree 0 Totally agree 0 Partially agree 3 Neither agree nor disagree 3 Partially disagree 2 Totally disagree 2 Totally agree 0 Partially agree 4 Neither agree nor disagree 1 Partially disagree 2 Totally disagree 3 235
Comparison of System Performance and User Interface It was easy to learn how to use the overriding controller I was easily able to set my desired illuminance with the overriding controller I felt comfortable working under this lighting system The ability of the system to maintain my chosen lighting was: Watt Stopper commercial system with handheld remote overriding controller Mote-based research system with GUI overriding controller Totally agree 9 9 Partially agree 1 1 Neither agree nor disagree 0 0 Partially disagree 0 0 Totally disagree 0 0 Totally agree 4 8 Partially agree 4 2 Neither agree nor disagree 0 0 Partially disagree 1 0 Totally disagree 1 0 Totally agree 5 8 Partially agree 4 2 Neither agree nor disagree 0 0 Partially disagree 0 0 Totally disagree 1 0 1 (poor) 0 0 2 0 0 3 0 0 4 0 0 5 3 2 6 5 4 7 (excellent) 1 4 Comparing the two overriding controllers I prefer: Handheld remote overriding controller GUI controller No Response 7 2 1 Other than different types of override, the two systems performed differently Yes No No Response 6 3 1 236
