N2 - Outdated Computer Vision (CV) toolkits for Tangible User Interfaces (TUI) have led to fragmented practices, diminished reproducibility, and reduced community support. This paper examines the past, present, and future trajectory of CV-TUI toolkits. Our scoping review of ACM literature (N=120) reveals a divergence between applications using the limited interactions of established toolkits like ReacTIVision and the fragmented, bespoke systems built for complex interactions, highlighting the need for advanced toolkits that enable accessible making. We found how ReacTIVision-based projects were primarily used in stationary tabletop settings with standard token events, while non-ReacTIVision projects explored unique interaction techniques in diverse configurations. Reflecting on these insights, we offer six suggestions for building the next-generation CV-TUI toolkits to support rapid prototyping of tangible interactions. This study provides the TUI community with an updated perspective to inform future research.
