Objective:The objective of this study is to identify the difference in the press behavior characteristics of 3D Touch, which is a new touch interaction of smart phones, and the existing ‘Tap and Long Press’ touch interaction, and to examine behavior changes upon feedbacks.
Background: Since 3D Touch is similar to the existing ‘Tap and Long Press’ touch interactions in terms of press behavior, which is likely to cause interference, it is necessary to conduct a preliminary study on behavior characteristics of touch interactions.
Method: In utilization of smart phones with the 3D Touch function to measure press behavior characteristics of touch interaction, an experiment was conducted where 30 subjects were given a task to press 30 buttons of touch interactions on the screen. During the experiment, two press behavior characteristics―maximum touch pressure and press duration―were analyzed. To grasp changes in behaviors upon feedbacks, the task was carried out in a condition where there was no feedback and in a condition where there were feedbacks of specific critical values.
Results: While there was no feedback given, subjects tended to press with much strength (318.98gf, 0.60sec) in the case of 3D Touch, and press the Long Press button for a while (157.12gf, 1.10sec) and press the Tap button with little strength only for a short moment (37.92gf, 0.10sec). 3D Touch and Long Press had an area of intersection in time, but when feedbacks of specific critical values were given, there were behavior calibration effects to adjust the press behavior characteristics of 3D Touch and Long Press.
Conclusion: Although interferences are expected between 3D Touch and Long Press due to the similarity of press behaviors, feedbacks induce behavior calibration. Hence, once feedbacks were provided with 3D Touch operated in an appropriate condition of critical pressure, interference between two motions can be minimized.
Application: The findings of this study are expected to be utilized as a basis for the values of optimal critical pressure, at which users can easily distinguish 3D Touch from Long Press which is the existing touch interaction.
