However, achieving the resolution, speed, and dynamic range needed for perceptual fidelity remains challenging. We present a dynamic tactile display that directly converts projected light into visible and tactile patterns via a photomechanical surface populated with millimeter-scale optotactile pixels. The pixels transduce incident light into mechanical displacements through photostimulated thermal gas expansion, yielding millimeter-scale displacements with response times of 2 to 100 milliseconds. Employing projected light for power transmission and addressing renders these displays highly scalable. We demonstrate optically driven displays with up to 1,511 addressable pixels - several times more pixels than prior tactile displays attaining comparable performance. Perceptual studies confirm that these displays can reproduce diverse spatiotemporal tactile patterns with high fidelity. This research establishes a foundation for practical and versatile high-resolution tactile displays driven by light. Dataset Description This dataset comprises thermal and mechanical responses of optotactile pixels and their subcomponents in response to optical stimulation. The dataset is split into four parts: data from imaging measurements collected with an IR camera and a high-speed camera (Fig. 2), data from mechanical measurements (force, displacement, and velocity) on the optotactile pixels (Figs. 1 and 3), data from human trials collected from participants during a set of perceptual studies (Fig. 4), and the remaining data (Supplementary Materials). For details on our numerical and experimental procedure, please see our publication. Imaging Data Thermal data from the optical absorber during laser irradiance, and data from membrane displacement collected with a high-speed camera associated with Fig. 2. Mechanical Data Free displacement and blocked force data associated with Figs. 1 and 3. Perceptual Data Perceptual data from experiments associated with Fig. 4. Supplemental Data Varied data from experiments, numerical simulations, and tables associated with Supplementary Materials.
