Development of a press and drag method for hyperlink selection on smartphones.

ABSTRACT

The present study developed a novel touch method for hyperlink selection on smartphones consisting of two sequential finger interactions press and drag motions. The novel method requires a user to press a target hyperlink, and if a touch error occurs he/she can immediately correct the touch error by dragging the finger without releasing it in the middle. The method was compared with two existing methods in terms of completion time, error rate, and subjective rating. Forty college students participated in the experiments with different hyperlink sizes (4-pt, 6-pt, 8-pt, and 10-pt) on a touch-screen device. When hyperlink size was small (4-pt and 6-pt), the novel method (time 826 msec; error 0.6%) demonstrated better completion time and error rate than the current method (time 1194 msec; error 22%). In addition, the novel method (1.15, slightly satisfied, in 7-pt bipolar scale) had significantly higher satisfaction scores than the two existing methods (0.06, neutral).
