“…Moreover, disabled users are a heterogeneous group differing individually, e.g., in abilities, use cases, and preferences, whose combination causes individually unique challenges [18]. Apart from that, disabled users prefer interfaces designed as close as possible to the norm and feel uncomfortable being dependent on special solutions [19]. Hence, despite differing requirements, design should always consider the inclusion aspect [19].…”

“…Despite the specific needs of BVI users, the design of the robot should aim for equal support for both BVI and sighted users, mitigating any potential for stigmatization [19]. To determine whether the handover robot fulfills those user needs and is equally proficient in assisting both BVI and sighted users, we require a theoretical foundation for selecting evaluation methods to assess robot-to-human handovers.…”

“…Throughout all phases apply emergent coordination arising from the interplay between perception and action [6], e.g., active, coordinating gaze behavior [13] design the interface as close as possible to the norm [19] coordinate handovers without eye contact [26] allow only one partner to move at a time [28] Prehandover Phase…”

The rapidly growing research on the accessibility of digital technologies has focused on blind or visually impaired (BVI) users. However, the field of human–robot interaction has largely neglected the needs of BVI users despite the increasing integration of assistive robots into daily life and their potential benefits for our aging societies. One basic robotic capability is object handover. Robots assisting BVI users should be able to coordinate handovers without eye contact. This study gathered insights on the usability of human–robot handovers, including 20 BVI and 20 sighted participants. In a standardized experiment with a mixed design, a handover robot prototype equipped with a voice user interface and haptic feedback was evaluated. The robot handed over everyday objects (i) by placing them on a table and (ii) by allowing for midair grasping. The usability target was met, and all user groups reported a positive user experience. In total, 97.3% of all handovers were successful. The qualitative feedback showed an appreciation for the clear communication of the robot’s actions and the handover reliability. However, the duration of the handover was seen as a critical issue. According to all subjective criteria, the BVI participants showed higher variances compared to the sighted participants. Design recommendations for improving robotic handovers equally supporting both user groups are given.

“…However, the designs from this prior work have assumed the motor abilities of people without motor impairments and, thus, little knowledge exists on how these interaction techniques, user interfaces, and applications can be used, if at all, by people with motor impairments. Actually, television control for people with various motor abilities has been little examined overall [59] compared to the attention dedicated to people with visual impairments [19,20,27].…”

We conduct an examination of the accessibility challenges experienced by people with upper body motor impairments when interacting with television. We report fndings from a study with N=41 people with motor impairments (spinal cord injury, cerebral palsy, muscular dystrophy) and document their challenges and coping strategies for using the TV remote control, but also their television watching experience and expectations of suitable assistive technology for television. Our results show that, despite several accessible remote control products available on the market, the majority of our participants preferred to DIY and hack, and to adopt coping strategies to be able to use conventional TV remote controls. We contrast their experience against that of a control group with N=41 people without impairments. We refect about the DIY culture and people with motor impairments, and we propose future work directions to increase the accessibility of interactions with television.
