Discoverability, the ability for users to find and execute features through a user interface, is a recurrent problem with Voice User Interface (VUI) design that makes it difficult for users to understand what commands are supported by a newly encountered system. We studied the effects of two different discoverability strategies proposed in literature, one which provides informational prompts automatically and one which provides help only when the user requests it by asking 'What Can I Say?'. Our study adopted a Wizard of Oz approach that allowed users to order food delivery by voice. Through statistical analysis, we confirmed the beneficial nature of both strategies, with significantly better task performance and higher usability scores in comparison to a baseline. This suggests designers should consider the use of a discoverability strategy in the design of VUIs. While no significant differences were found between the strategies, a majority of the participants highlighted their preference for the 'What Can I Say?' strategy if they were to use the VUI more frequently. Finally, we reflect on the implications for the design of VUIs, highlighting the need to distinguish between initial use and longer-term use in the selection of a strategy.

Voice interactions on mobile phones are most often used to augment or supplement touch based interactions for users' convenience. However, for people with limited hand dexterity caused by various forms of motor-impairments voice interactions can have a significant impact and in some cases even enable independent interaction with a mobile device for the first time. For these users, a Mobile Voice User Interface (M-VUI), which allows for completely hands-free, voice only interaction would provide a high level of accessibility and independence. Implementing such a system requires research to address long standing usability challenges introduced by voice interactions that negatively affect user experience due to difficulty learning and discovering voice commands.In this paper we address these concerns reporting on research conducted to improve the visibility and learnability of voice commands of a M-VUI application being developed on the Android platform. Our research confirmed long standing challenges with voice interactions while exploring several methods for improving the onboarding and learning experience. Based on our findings we offer a set of implications for the design of M-VUIs.

Keyboard shortcuts have been proven to be the most efficient method of issuing commands in computer software. Using the mouse in graphical user interfaces provides an intuitive but slow method for executing functions in a software. Many fail to make the transition to faster modalities, such as keyboard shortcuts. This is not just the case for novices, but also users with years of experience. This study examines the research on this behavior, as well as how the concepts of nudging and ambient suggestion can be used to actively encourage and support the usage of keyboard shortcuts. Based on this research, a design is proposed and implemented in a simple word processor application. A user experience evaluation was done, by having participants perform writing and formatting tasks inside the application. Using the Microsoft Reaction Card Method followed by a semi-structured interview, the users elaborated on their experience. In the interviews topics and questions of motivation, distraction, and annoyance were raised. The results showed that most participants found the system convenient and helpful in learning shortcuts without being too obtrusive. There are promising first indications of it having potential in promoting the usage of keyboard shortcuts, however further research is required in order to make any generalizations.
