CASE # 1
At 1:24 a.m. March 18,1990 as St. Patrick's Day came to a close thieves struck the Isabella Stewart Gardner Museum in Boston MA. The biggest art theft in U.S. history remains unsolved.
A five million dollar reward has been offered for the safe return of the art. Although statutes for criminal prosecution may have lapsed, the paintings are still considered to be stolen property.
The most valuable painting taken is Jan Vermeer's "The Concert". It is one of approx. 35 known works by the great Dutch painter. If you have any information about this case please contact the appropriate officials

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

System requirements(and possible solutions)
Selection of alarm sector (touchscreen, pointer, extrabuttons, or a combination?) User ID (fingerprint, eye scan, handwriting, virtualkeyboard, palm print?)
Monitor > 4 sectors (touchscreen, pointer, extrabuttons, automatic, back side of device?)
Make notes or log (speech, write, virtual keyboard?)
Transmit data (wireless, continuous, on-line, dockingstation, 3½ floppy drive?)
