Apple’s 3D-Touch Technology and its Impact on User Experience Nicolas Suarez-Canton Trueba 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.
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.
A. Accuracy • 3D-Touch to quantify pressure. • 2004 study 1 —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. 3D-Touch Button Traditional Slider
Start Rating (starts timer) Visual feedback is provided (rating bar) 3D-Touch Button (pressure sensitive).
Evaluation • Number of attempts. • Time it takes to reach target value.
B. Cognitive Overhead • Pressure sensitive notifications. • Haptic feedback. • Streamlined notification interaction.
• “Shape” Game Rules: • Unfamiliar to users and easy • Green + Square to play. • Yellow + Triangle • Hypothesis : 3D-Touch is a • Red + Circle less disruptive notification system. • Blue + Diamond
Evaluation • From dismissal of notification: how much time does the user take to make the next move?
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.
Color panel grows. Haptic feedback—awaiting for confirmation. Pressure sensitive buttons.
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.
