2 Johan F. Hoorn2 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 MAJOR ART THEFTS "A Search For The World's Most Wanted Art" We are seeking information about these cases: 1. The Vanishing Vermeer $5,000,000 reward Boston, MA USA Gardner Museum March 18, 1990$5,000,000 reward

6 Johan F. Hoorn6 Off-line Design of a Handheld Security Monitor HandSeM Off-line Design of a Handheld Security Monitor HandSeM How to switch if there are eight sectors? Alarm Guard’s name - touchscreens? - pointer? - extra buttons? - automatic? REWARD

7 Johan F. Hoorn7 Off-line Design of a Handheld Security Monitor HandSeM Off-line Design of a Handheld Security Monitor HandSeM How to switch if there are eight sectors? - touchscreens? - pointer? - extra buttons? - automatic? - or use back side? REWARD

9 Johan F. Hoorn9 Off-line Design of a Handheld Security Monitor HandSeM Off-line Design of a Handheld Security Monitor HandSeM REWARD Alarm I run to back - wireless, continuous, and on-line? How to transmit data? - docking station?

10 Johan F. Hoorn10 Off-line Design of a Handheld Security Monitor HandSeM - or use the floppy drive?

11 Johan F. Hoorn11 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

12 Johan F. Hoorn12 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?)

13 Johan F. Hoorn13 First usability test by playing scenario’s: What functionality is (not) needed?  Guard is alone and taken hold of by art thief  Guard is in late-night firefight and wants back-up  Guard works while public is in museum  Colleagues bring together a search posse
