Apple’s 3D-Touch Technology and its Impact

  • n User Experience

Advisor: Chris Fernandes CSC-499 Winter 2017

3D-Touch

  • Pressure sensitive touchscreen technology.
  • Goal: evaluate the usefulness of 3D

Touch as an interface for a mobile application.

SLIDE 3

Approach

  • How does 3D-Touch affect the user experience of

mobile applications?

  • Interesting aspects of user experience:
  • A. Accuracy.
  • B. Cognitive Overhead.
  • C. Error recovery.
slide-4
SLIDE 4
  • A. Accuracy
  • 3D-Touch to quantify pressure.
  • 2004 study1—pressure sensitive styluses for

performing selection tasks:

  • Hour-long training required if no visual feedback.
  • 1. Ramos, Gonzalo, Matthew Boulos, and Ravin Balakrishnan. "Pressure widgets." Proceedings of the

SIGCHI conference on Human factors in computing systems. ACM, 2004.

Testing Accuracy

  • Exact target vs. ± 3

range.

  • User is aware of

treatment.

  • Within-subject

study.

slide-7
SLIDE 7

Evaluation

  • Number of attempts.
  • Time it takes to reach target value.
slide-8
SLIDE 8
  • B. Cognitive Overhead
  • Pressure

sensitive notifications.

  • Haptic

feedback.

  • Streamlined

notification interaction.

slide-9
SLIDE 9
  • “Shape” Game Rules:
  • Green + Square
  • Yellow + Triangle
  • Red + Circle
  • Blue + Diamond
  • Unfamiliar to users and easy

to play.

  • Hypothesis: 3D-Touch is a

less disruptive notification system.

slide-10
SLIDE 10

Evaluation

  • From dismissal of notification: how much time

does the user take to make the next move?

slide-11
SLIDE 11
  • C. Error Recovery
  • 3D-Touch’s “Preview” environment:
  • As pressure increases, the user can see a

content preview.

  • If user releases pressure, the content preview

aborts.

  • Hypothesis: 3D-Touch works as an error recovery

mechanism that prevents unwanted navigation.

slide-13
SLIDE 13

Evaluation

  • Number of attempts.
  • Time it takes to find the target color.

Current Status

  • Accuracy experiment has been fully implemented.
  • Plan to run the experiment next week.
  • Cognitive Overhead and Error Recovery

experiments are future work.
