Motivation

Daily office work is highly fragmented• While working at the desk, one has to maintain an • overview of upcoming appointmentsSoA reminders are obtrusive or require focused atten-• tion, difficult to reach work “flow”Ambient light can be used to remind users of upcom-• ing events in the periphery

Results

Participants were able to judge available time• Participants felt well informed on progress of time• Participants did not feel disturbed• Exponential patterns receive better ratings•

Conclusion/Outlook

Ambient Timer may be a good alternative to SoA re-• minders that are obtrusive or require focused attenti-on, e.g. pop-ups or checking the clockFuture work: Compare Ambient Timer to SoA remin-• ders; conduct long-term user study.

Design

Ambient Timer continuously informs users on when • the time for the next appointment has comeWe used an LED-frame on the backside of a monitor • to create an ambient light display uWe studied a set of 8 light patterns combining 4 pa• ra-meter changes v with 2 different change modes w in an experiment with controlled light settingsParticipants were asked to write essays for 10 minutes • and use Ambient Timer for timing the task‘s end.
