Tap Input as an Embedded Interaction Method for Mobile Devices

1
Tap Input as an Embedded Interaction Method for
Mobile Devices

• S. Ronkainen et al.

2
Strengths

• Studying social acceptance before implementation
• Imaginative scenarios
• Implementation with deployment into Nokia mobile
  phones
  
• Useful! alarm snooze

3
Weaknesses

• Lots of possible false activations
  accelerometers
  
• Web study one sided, no interaction a
  Likert-scale could help

4
Suggestions

• Some explanation of how the tapping interface
  works might have been useful
  
• More studies of learning effects
• More effective use of space in graphs labels!
• Allow users to suggest gestures

5
Progress since paper

• Sensored steering wheel?

6
LucidTouch A See-Through Mobile Device

• D. Wigdor et al.

7
Strengths

• Thorough study of background, similar devices
• Very innovative idea, succeeded to implement and
  test it

8
Weaknesses

• Technology not there yet camera on a boom?!
  Micro-imaging Array
  
• Some scenarios might need bimanual operation
• Problem with subjects from lab (6)
• Multi-touch only on background

9
Suggestions

• Not to draw far-fetched conclusions based on a
  user study conducted on 6 lab co-workers

Driving Performance While Engaged in MP-3 Player
Interaction

• S. Chisholm et al.

11
Strengths

• Relevance!
• Clear in contents
• Clear statistical analysis
• Useful learning curve analysis

12
Weaknesses

• Driving performance measures? Variance of lane
  position, steering wheel angle, velocity
  
• On-road glances 28 during baseline?
• No gender info on subjects
• Showing only 3 variables of 11
• Definition of fixations?
• Reaction time results what about the mean value
  for baseline?

13
Suggestions

• Include standard performance measures
• Would be interesting to compare the manual
  interface to the iPod with speech user interface
  (Sync)
  
• More sensible charts
• Would a motion base help with braking when
  following cars?

Progress since paper

• Speech user interfaces appeared in cars for
  controlling MP3 players
