In recent times, Tangible User Interfaces (TUI) have introduced a new design paradigm for Human Computer Interaction (HCI). TUIs provide an interface to the digital world by providing physical representations of digital information with the aim to overcome the limitations of screen-based interfaces. Regardless of their potential, there is a lack of recent research in how to apply TUIs to daily physical processes, such as cooking. In response to this, we propose SPICE (Smart Projection Interface for Cooking Enhancement). SPICE investigates the integration of Tangible User Interfaces (TUIs) in a kitchen setting, aiming to transform cooking experiences from traditional text-based recipe-following to tangible interactive processes. SPICE consists of different elements such as a tracking system, an agent-based software, and vision large language models to create and interpret a kitchen environment where recipe information is projected onto the same cooking space. Experiments involved 30 participants to assess the efficiency, confidence, and taste perception when using SPICE compared to traditional methods. The result indicates that SPICE allowed participants to perform the recipe in less stops and shorter time, all whilst improving self-scored ratings of efficiency, confidence and even taste. This research offer insights about the potential use of TUIs to improve everyday activities, paving the way for future research in HCI and new computing interfaces. |
