4. Problem
1m

5. Solution

6. HaNS
• Haptic Notification System
• Novel wireless, wrist-worn, chair speaker
communication system
• automation, tactile cue for time-managing

7. FSR: Force Sensitive Register

9. Related Works
• Previous research missed non-visual awareness solution
• Sensory overload -> tactile feedback notifiable

10. Iterative design & Pilot
• To learn which vibration pattern, mapping
easy for user
• Need for detailed timing information for
unplanned situation

11. Observation

12. Evaluation

13. Result
• Modify positively chair-speaker loop
• Through reliable cue delivery
cognitive offloading
channel privacy
• Improve time awareness

14. 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”

15. Detailed result
• Conflict with internal control
speaker’s need to internally strategize
pacing and thereby avoiding
• Halfway reminder – personalized cue

16. Discuss
• Sensory, cognitive, social outcomes of their
interplay, 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

17. Limitation
• Not “in the wild” study – limited control
• Weak for generalization

18. Sharing
• Just by alone
• Helping time awareness of pacing
• Using smartphone or galaxy gear
• Time estimation or time allocation in
authoring tool
• First write down result taken for granted
or fancy result got fewer occupation
