Problem

1m

Solution

HaNS

• Haptic Notification System• Novel wireless, wrist-worn, chair

speaker communication system• automation, tactile cue for time-man-

aging

FSR: Force Sensitive Register

Related Works

• Previous research missed non-visual awareness solution• Sensory overload -> tactile feedback notifiable

Iterative design & Pilot

• To learn which vibration pattern, mapping easy for user

• Need for detailed timing information for unplanned situation

Observation

Evaluation

Result

• Modify positively chair-speaker loop• Through reliable cue delivery

cognitive offloading channel privacy

• Improve time awareness

User’s comment

• “watching the signs and waiting until speaker notice it”

• Audience knowing from “I’m getting buzzed”

• whether they ahead of time or behind the time

• Tactile cues were salient• “can’t prop up to face, lays flat on table”• “forget to start timer”

• “who went over chose to ignore it”

Detailed result

• Conflict with internal controlspeaker’s need to internally strate-gize pacing and thereby avoiding

• Halfway reminder – personalized cue

Discuss

• Sensory, cognitive, social outcomes of their in-terplay, context.

• Implication for speaker- Private is better – minimize audience awareness- acknowledgement should be optional- personalize for cue time points, intensity, duration, signal mapping

• For chair- Echo the speaker’s experience – sending same signal- provide additional direct, private communication channel – timer start, Q&A session- easily adjust timing

Limitation

• Not “in the wild” study – limited con-trol

• Weak for generalization

Sharing

• Just by alone• Helping time awareness of pacing• Using smartphone or galaxy gear• Time estimation or time allocation in
