This paper investigates the effects of an expandable socket attachment for mobile phone grip on stationary (while seated) and mobile (while walking on a treadmill) text entry. An exploratory study (N = 12) failed to identify a significant effect of the attachment on text entry speed, accuracy, and error correction effort in either settings. But participants performed relatively better with the attachment while walking. Participants also did not perceive the attachment to affect their text entry speed and accuracy. However, significantly more participants wanted to use it in mobile settings, presumably to increase the safety of their devices.
