    Talking to Stupid?!? Improving Voice User Interfaces
    (Mensch und Computer 2019 - Usability Professionals, 2019) Biermann, Maresa; Schweiger, Evelyn; Jentsch, Martin
    Voice User Interfaces have become part of our daily life by being integrated in smartphones, computers, smart home devices and many other consumer products. However, despite their potential, voice assistants like Alexa, Google Assistant or Siri are not that widely used. Why is that? What are their pain points? How can the interaction and dialog flow between the user and the voice user interface (UI) be improved? In a research and development project at designaffairs, insights from user research were used to develop an interaction and dialog concept for a voice UI. The concept draft was refined with user feedback to develop a software prototype. This early voice UI prototype was then evaluated in a user test which demonstrated its potential in better satisfing the user’s wishes for a natural dialog flow. Overall, the iterative user centered approach of the project revealed crucial pain points of the human-machine interaction and further opportunity areas to meet the user’s need.

    User Preferences of Voice Controlled Smart Light Systems
    (Mensch und Computer 2019 - Tagungsband, 2019) Faltaous, Sarah; El Jaki, Salma; Schneegass, Stefan
    The use of smart home devices is widely spreading. Several ways exist to control such devices. Besides classical approaches such as buttons and remote controls, voice user interfaces (VUIs) are showcased as a primary input method in the context of smart home. Yet, few studies investigated the user’s behaviour and experience with such newly offered input techniques. In this research, we carried out a field study to investigate the user preferences in using a VUIs for controlling a smart lighting system. The results indicate that the usage frequency drops after the first days and that users tend to use the system mainly once in the evening.
