Motion Gestures
- A gesture performed by physically
translating or/and rotating the device.

Designing Motion Gestures
- Say you wanted to design a motion
gesture to answer an incoming phone call. What motion gesture would you use?
SLIDE 13
Is there agreement?

Flick Shake Circular Place phone to ear
SLIDE 14
Is there agreement?
Act on a selection
- Checkmark
- Shake
- Flick
- Rotate Screen

17 Unique Gestures Did not have an agreement for
– Act on selection – Switch to next application – Switch to previous application
SLIDE 15
Agreement?
SLIDE 16
Motion Gesture Taxonomy
- Two classes of taxonomy dimensions
– Gesture Mapping
- Nature – physical mapping to objects
- Context – requires a specific context
- Temporal – occurs during or after a gesture is performed
– Physical Characteristics
- Kinematic Impulse - range of jerk
- Dimension - number of axes involved in the movement
- Complexity – simple or compound gesture

SLIDE 17

Gestures tend to be simple discrete gestures involving a single axis with low kinematic impulse

Bi-Level Thresholding
Observation: On false negative, user repeats gesture Safety Net
- Observing two possible gestures = observing
- ne highly probable gesture
- One tightly thresholded initial model
- One loosely thresholded double model
SLIDE 21
Bi-level Thresholding Recognition
Passive State Primed State Fire Action
Everyday Motion Everyday Motion Loose Threshold Tight or Loose Threshold Timeout Tight Threshold Reset
SLIDE 22
Evaluation
- 2/3 of gestures recognized in the Bi-level
case were detected by the double low model
SLIDE 23
Current Question
How can we guide users, i.e. allow them to gradually improve, as we build interfaces that are increasingly clever?

A Few Words About Waterloo
- Co-operative education
- MITACS internships
- Collaborative research programs
– Networks of Centres of Excellence – Ontario Research Fund – Research Excellence – NSERC Collaborative Research and Development Grants
SLIDE 34
What about IP?
- Policy 73:
“UW’s intellectual property policy at its highest level of interpretation grants ownership of any intellectual property (IP) to the creators of the
- IP. UW embraces the philosophy that providing
incentive through IP ownership is the best motivator to ensure that commercialization of research occurs for broad societal and economic benefit.”
