“…This could be presented as a 'virtual assistant', guiding the user through the development process. There has been an increase in the use of virtual assistants in a variety of disciplines including healthcare (Teixeira et al, 2014), sales (Beldad, Hegner, & Hoppen, 2016), and aiding in research (Hasler, Tuchman, & Friedman, 2013. ).…”

Much research has been carried out into the integration of User Experience and the Agile software development methodology. However, there has been no formal attempt to develop a computerbased management system to aid in the integration of these two concepts. This paper outlines the initial development of such a system; UX-Vision. It includes how the system operates, the design of its user interface, and the data structure. There is also discussion on how the system could be developed further to include a virtual assistant to indicate when and how UX activities should be carried out within Agile software development.User Experience, Agile, Virtual Assistant, Management Platform.

“…The tablet has the highest acceptance rate by the elderly but depends on previous PC usage [31] and training received [27], especially from family [32]. Virtual assistants and voice activations also provide a way for the elderly to increase technology acceptance [33,34].…”

Several social and technical trends support the elderly's desire to live independently in their preferred environment, despite their increasing medical needs, and enhance their quality of life at home. Ambientassisted living (AAL) has the capabilities to support the elderly and to decrease their dependency on formal or informal caregivers. We provide a review of the technological challenges that were identified as inhibiting factors in the past decade and then present recent technological advances, e.g., cloud computing, machine learning, artificial intelligence, the Internet of Things. We also fill the gap in the current literature in regard to specific AAL solutions and propose fourthgeneration AAL technology design. We find that most informal caregivers are family members who are medically untrained and that the use of advanced analytical processes on AAL-generated data could significantly increase symptom identification. We also present the implications and remaining challenges along with recommendations for future research.

“…Furthermore, the quality and speed of the system feedback as well as the recognition accuracy of the spoken components are key factors to a better user experience. A recent study evaluated VPA to provide the elderly with a wide range of online services such as weather information and social networking [29]. Results demonstrated the need for several input/output modalities, distribution of modalities across different devices (PCs, Tablets, etc.…”

Until now the virtual assistants (like Siri, Google Now and Cortana) have primarily been confined to voice input and output only. Is there a justification for voice only confinement or can we enhance the user experience by adding a visual output? We hypothesized that providing a higher level of visual/auditory immersion would enhance the quality of user experience. In order to test this hypothesis, we first developed 4 variants of virtual assistant, each with a different audio/visual level of immersion. Developed virtual assistant systems were the following; audio only, audio and 2D visual display, audio and 3D visual display and audio and immersive 3D visual display. We developed a plan for usability testing of all 4 variants. The usability testing was conducted with 30 subjects against eight (8) dependent variables included presence, involvement, attention, reliability, dependency, easiness, satisfaction and expectations. Each subject rated these dependent variables based on a scale of 1-5, 5 being the highest value. The raw data collected from usability testing was then analyzed through several tools in order to determine the factors contributing towards the quality of experience for each of the 4 variants. The significant factors were then used develop a model that measures the quality of user experience. It was found that each variant had a different set of significant variables. Hence, in order to rate each system there is a need to develop a scale that is dependent upon the unique set of variables for the respective variant. Furthermore, it was found that variant 4 scored the highest rate for Quality of Experience (QoE). Lastly several other qualitative conclusions were also drawn from this research that will guide future work in the field of virtual assistants.
