abstract = {Being able to live independently and self-determined in one's own home is a crucial factor for human dignity and preservation of self-worth. For people with severe physical impairments who cannot use their limbs for every day tasks, living in their own home is only possible with assistance from others. The inability to move arms and hands makes it hard to take care of oneself, e. g. drinking and eating independently. In this paper, we investigate how 15 participants with disabilities consume food and drinks. We report on interviews, participatory observations, and analyzed the aids they currently use. Based on our findings, we derive a set of recommendations that supports researchers and practitioners in designing future robotic drinking and eating aids for people with disabilities.},

abstract = {Accurate depth perception in co-located teleoperation has the potential to improve task performance in manipulation and grasping tasks. We thus explore the operator's visual space and design visual
cues using augmented reality that aim to facilitate the positioning of the gripper above a target object before attempting to grasp it. The designs we propose include a virtual circle (Circle), virtual extensions (Extensions) from the gripper's fingers, and a color matching design using a real colormap with matching colored virtual circles (Colors). We conducted an experiment to evaluate these designs and the influence of distance from the operator to the workspace and the target object's pose. Here, we report on time, success, and perceived certainty in a grasping task. Our results show that a shorter distance leads to higher success, faster grasping time, and higher certainty. Concerning the target object's pose, a clear pose leads to higher success and certainty but interestingly slower task times. Regarding the design of cues, our results reveal that the simplicity of the Circle cue leads to the highest success and outperforms the most complex cue Colors also for task time, while the level of certainty
seems to be depending more on the distance than the type of cue. We consider that our results can serve as an initial analysis to further explore these factors both when designing to improve depth perception and within the context of co-located teleoperation.},

abstract = {Mind-wandering, i.e., letting the mind drift away from the task at hand, is mostly seen as a state of mind to avoid, as it may negatively impact the current task. However, evidence in cognitive science shows that mind-wandering can also positively affect creativity and problem-solving. Still, there is a lack of technological solutions to facilitate and utilize mind-wandering in such a specific way. In this short paper, we present MuseFlow, a video game designed to facilitate mind-wandering deliberately. Our study shows that MuseFlow induces mind-wandering significantly more often compared to a demanding game condition while maintaining the players' motivation to play and succeed in the game.},
