“…To address this issue, the aim of the final design was to create a smart speaker that allows people to explore the beauty of music visually. By incorporating visual elements into the audio experience, users can not only listen to music but also visually perceive its expression and impact [21]. This integration of audio and visual stimuli aims to amplify the beautiful details in life and provide a multi-sensory experience.…”

The current limitations of user–product interaction with smart speakers have spurred the proposal of a model to circumvent these challenges. We used the ViP design principle to redefine the user’s approach to interacting with the product. Throughout the deconstruction and design stages, we explored the structure and function of the conventional product across three layers: the product layer, interaction layer, and context layer using three models. We used the hierarchical analysis method to effectively quantify the design factors affecting user experience and identify the key design factors. This approach enabled us to contextualize the smart audio system, explore the interaction dynamics between the product and the user, and provide valuable insights on designing new products. A questionnaire method was used to survey 67 users, and a reliability test was conducted to ensure the validity of the questionnaire v (Cronbach’s coefficient α = 0.868). A pairwise comparison of factors was conducted on a 1–9 scale, with weights determined through the analytic hierarchy process (AHP). The combination of the ViP design principle and hierarchical analysis presents a novel and objective paradigm to guide designers to customize product characteristics (design attributes) to enhance user human–computer interaction experience. We validated the feasibility of the innovative design approach using the smart speaker model, offering insights for research on designing similar products.

“…Novices may need to sketch ideas or use pseudocodes in natural language before translating them with formal methods whereas experts can circumvent informal steps and proceed with formal ones. Because of these differences, a further semi-formal prototyping emerged as less strict than formal and more accurate than informal approaches in Chklovski, Ratnakar, and Gil (2005) and Law et al (2023). Such a pragmatic balance considers using informal data such as sketches to produce quick and lightweight initial design and then to use formal methods to eliminate ambiguities and provide accurate description to the UI when necessary.…”

The emergence of Natural User Interface (NUI) two decades ago brought a lot of potential by supporting intuitive and multimodal interaction and leveraging human sensorimotor skills. Systematic prototyping and development of NUI, however, received much less attention, and legacy methods of the previous Graphical User Interface (GUI) were applied to develop NUIs. This has led to usability issues in many cases. In this paper we introduce a systematic lightweight approach to aid designers and developers in prototyping NUIs based on the context of interaction. We demonstrate the application of this approach through the development of a pen-based NUI.
