More and more people use virtual assistants in their everyday life (e.g., on their mobile phones, in their homes, or in their cars). So-called vehicle assistance systems have evolved over the years and now perform various proactive tasks. However, we still lack concrete guidelines with all the specifics that one needs to consider to build virtual assistants that provide a convincing user experience (especially in vehicles). This research provides guidelines for designing virtual in- vehicle assistants. The developed guidelines offer a clear and structured overview of what designers have to consider while designing virtual in-vehicle assistants for a convincing user experience. Following design science research principles, we designed the guidelines based on the existing literature on the requirements of assistant systems and on the results from interviewing experts. In order to demonstrate the applicability of the guidelines, we developed a virtual reality prototype that considered the design guidelines. In a user experience test with 19 participants, we found that the prototype was easy to use, allowed good interaction, and increased the users’ overall comfort.
To remain competitive, businesses need to develop innovative and profitable products, processes and services. The development of innovation relies on novel ideas, which can be generated during creative workshops. In this context the Design Thinking approach, a problem-solving methodology based on collaboration, user-centricity and creativity, may be used. However, guidance and moderation of this process require a vast amount of skills and knowledge. As technologies like artificial intelligence have the potential of making machines our collaboration partner in the future, creating virtual assistants adapting human behaviors is promising. To reduce cognitive dissonance and stress on both the moderators and participants, we investigate the potential of a virtual assistant to support moderation in a Design Thinking process to improve innovative output as well as perceived satisfaction. We therefore developed design guidelines for virtual assistants supporting creative workshops based on qualitative expert interviews and related literature following the Design Science Research Methodology.
In order to generate valuable innovations, it is important to come up with potential beneficial ideas. A well-known method for collective idea generation is Brainstorming and with Electronic Brainstorming, individuals can virtually brainstorm. However, an effective Brainstorming facilitation always needs a moderator. In our research, we designed and implemented a virtual moderator that can automatically facilitate a Brainstorming session. We used various artificial intelligence functions, like natural language processing, machine learning and reasoning and created a comprehensive Intelligent Moderator (IMO) for virtual Brainstorming.
