“…1.2. Voice-User Interfaces in Human-Robot Interaction for Sighted and Visually Impaired Users BVI people are the power users and, consequently, experts of VUIs [19], with voice commands being their most frequently used interaction modality [20]. In a study, all included BVI subjects used TalkBack or VoiceOver for smartphone interaction in daily life [12].…”

“…In a study, all included BVI subjects used TalkBack or VoiceOver for smartphone interaction in daily life [12]. Furthermore, a study in Germany showed that 88% of included BVI subjects regularly use common voice assistants such as Siri [19]. BVI users also use speech more frequently for input, generate longer messages, and are more satisfied with speech interfaces than sighted people [21].…”

“…Ref. [19] concludes that BVI people as power users of VUIs "may be able to correctly interpret and retrieve longer and more complex speech responses" (p. 2). Supporting daily activities, VUIs allowing for easy and quick entry [13] present a high potential to make impaired people more independent.…”

“…Whereas some BVI subjects evaluated the VUI as being far to slow, this was not the case for blinded subjects. One possible explanation is that BVI people have been found to have greater serial memory, enabling them to correctly interpret and retrieve longer and more complex speech responses [19].…”

Handing over objects is a collaborative task that requires participants to synchronize their actions in terms of space and time, as well as their adherence to social standards. If one participant is a social robot and the other a visually impaired human, actions should favorably be coordinated by voice. User requirements for such a Voice-User Interface (VUI), as well as its required structure and content, are unknown so far. In our study, we applied the user-centered design process to develop a VUI for visually impaired humans and humans with full sight. Iterative development was conducted with interviews, workshops, and user tests to derive VUI requirements, dialog structure, and content. A final VUI prototype was evaluated in a standardized experiment with 60 subjects who were visually impaired or fully sighted. Results show that the VUI enabled all subjects to successfully receive objects with an error rate of only 1.8%. Likeability and accuracy were evaluated best, while habitability and speed of interaction were shown to need improvement. Qualitative feedback supported and detailed results, e.g., how to shorten some dialogs. To conclude, we recommend that inclusive VUI design for social robots should give precise information for handover processes and pay attention to social manners.
