Exercise: Design HandSeM from the options just presented Provide the most functionality with the least number of buttons and gadgets Avoid buttons or options with multiple functions Operation of device should be intuitively clear Play a scenario to explore the user tasks Johan F. Hoorn
System requirements (and possible solutions) Selection of alarm sector (touchscreen, pointer, extra buttons, or a combination?) User ID (fingerprint, eye scan, handwriting, virtual keyboard, palm print?) Monitor > 4 sectors (touchscreen, pointer, extra buttons, automatic, back side of device?) Make notes or log (speech, write, virtual keyboard?) Transmit data (wireless, continuous, on-line, docking station, 3½ floppy drive?) Johan F. Hoorn
First usability test by playing scenario’s: What functionality is (not) needed? Guard works while public is in museum Guard is in late-night firefight and wants back-up Guard is alone and taken hold of by art thief Colleagues bring together a search posse Johan F. Hoorn
