Introduction
Related Work (1/2)
• Design dimensions– Information Capacity
– Notification Level
– Representational Fidelity
– Aesthetic Emphasis
Related Work (2/2)
• Ambient displays that use light as mean of communication
• Ambient displays for meeting rooms
Design of the Ambient Display (1/4)
• Concept Description– Meeting duration
– Meeting schedule
– Activity duration
– Progress of the meeting
– Feedback on individual contribution time
– Notification of transitions between activities
Design of the Ambient Display (2/4)
• Design Goals– Provide contextual information in an unobtrusive way
– Reduce cognitive load for pacing and time keeping
– The system should support different roles and activities within a meeting
Design of the Ambient Display (2/4)
• Design Goals– Invite meeting participants to a more accountable use of
common time
– Seek a balance between aesthetical and information quality
Design of the Ambient Display (3/4)
• Design Choices– Sared display
– Low information capacity
– Linear representation of time
– Pre-attentive processing
– Static status display, subtle transitions
Design of the Ambient Display (3/4)
• Design Choices– Multiple visualization modes to support different roles of
participants
– Convenient location for higher cognitive demanding tasks
– Light beams as information medium
Design of the Ambient Display (4/4)
• Evaluation and Research questions
First prototype (1/2)
• Low-Fidelity graphical implementation– Meeting progress (size), Meeting schedule (color),
Presentation mode (color intensity)
First prototype (1/2)
• Low-Fidelity graphical implementation– Notifications
• Time slot almost elapsed (dynamic change in length)
• Upcoming change in activity (color transition)
• Approaching end of presentation time (blink)
First prototype (2/2)
• In-Field Concept Evaluation and Results
First prototype (2/2)
• In-Field Concept Evaluation and Results– Design Choices
– Perception, Interpretation, Experience
Second prototype (1/2)
• Halogen Spots Implementation– Meeting progress (direction),
Meeting schedule (colors), Presentation mode (intensity)
Second prototype (1/2)
• Halogen Spots Implementation– Notifications
• Time slot almost elapsed (intensity)
• Approaching end of presentation (blink)
Second prototype (2/2)
• Controlled Context Evaluation and Results
Second prototype (2/2)
• Controlled Context Evaluation and Results– Design Choices
– Perception, Interpretation
Conclusions & Recommendations
• Conclusions
Conclusions & Recommendations
• Further development– Additional investigation is needed to better understand the
level of information detail our display requires
– Special attention needs to be paid to users’ expectations towards the system’s behavior
– The design of an interface and interaction styles allowing users to interact explicitly with such an information decoration system before and during the meeting
