Objective: This study aims to identify the effects of hand size, hand dominance, and device size on the grip posture of smartphones for physical and graphical UIs.
Background: An inappropriate user interface (UI) causes an inappropriate grip posture and is a cause of lowering smartphone usability. Although studies on smartphone UI elements affecting the gripping posture have been conducted in various fields, there has been no study on the effect of hand dominance for physical and graphical UIs together.
Method: Forty participants with different hand sizes simulated texting and web-surfing tasks using smartphone mock-ups with screen sizes of 3.0" to 7.0" and their grip postures were recorded using web cameras. Four major grip postures (side grip, back-support grip, bottom-support grip, and upper grip), classified based on the positions of the fingers on the smartphone and the shape of the grip, were identified.
Results: It was found that the grip posture distributions for physical UI and graphical UI varied largely by device size (up to 37.1%), moderately by hand size (up to 14.3%), and slightly (up to 3.0%) by hand dominance.
Conclusion: This study found that the frequency distribution of use of the grip posture was significantly changed according to the user interface, anthropometric information such as hand length and dominant hand, and smartphone design factors such as device size.
Application: The information of the grip posture distributions identified in the present study can be utilized to determine the optimal locations of smartphone interfaces for better usability.
