Manipulations. Motivational information
Manipulations. We manipulated the direction of the tablet mounted on top of the robot and the information displayed on the tablet (Figure 1 and Table 1). In conditions A (Figure 1a) and B (Figure 1c) a set of blink- ing eyes was displayed on the tablet either facing the participants or the walking direction. In condition C we programmed the tablet to display route information, i.e., the remaining distance to the target (Figure 1e). A condition having the tablet mounted on the front of the robot, while displaying route information was deemed unneces- sary as this would neither provide information for the participants 1 Human Media Interaction group, University of Twente, the Netherlands, email: x.x.xxxxxx, x.x.x.xxxxxx, x.x.xxxxxxxxxxx, x.xxxxxx @xxxxxxx.xxxxxxx.xx, x.x.xxxxxx, x.xxxxx, x.xxxxx @utwente.nl http://www.spencer.eu following the robot, nor for other people present in the laboratory.
