The general problem addressed in this paper is supporting a more efficient communication between remote users, who control telepresence robots, and people in the local setting. The design of most telepresence robots does not allow them to perform gestures. Given the key role of pointing in human communication, exploring design solutions for providing telepresence robots with deictic gesturing capabilities is, arguably, a timely research issue for Human-Robot Interaction. To address this issue, we conducted an empirical study, in which a set of low fidelity prototypes, illustrating various designs of a robot's gesture arm, were assessed by the participants (N=18). The study employed a mixed-method approach, a combination of a controlled experiment, elicitation study, and design provocation. The evidence collected in the study reveals participants' assessment of the designs, used in the study, and provides insights into participants' attitudes and expectations regarding gestural communication with telepresence robots in general
