What is it about?
Vision - Based Tactile Sensors (VBTS) are amazing devices that combine the functions of vision and touch. This review sums up the recent progress of VBTS, from how they sense things to their applications. It focuses on performance - assessing parameters like range, spatial resolution, and sensitivity, as well as error, temporal parameters, miniaturization, and stability.The article also discusses how to enhance the above - mentioned performance through the design of hardware materials and structures or software data - processing methods. It also explores VBTS's sensing capabilities and application scenarios, such as item identification, grasp control, material property detection, and multimodal perception.Finally, the review offers insights into the future of VBTS. We hope it can help researchers quickly understand VBTS capabilities and performance, and provide references for choosing or designing different VBTS modules.

Why is it important?
Performance parameters are not only the basis for evaluating the capabilities of vision - based tactile sensors but also the key guidelines for guiding their design and optimization. This review helps researchers quickly understand and compare different VBTS, and get to know the development status and measurement capabilities of VBTS by standardizing the concepts of performance parameters and comparing theperformance indicators of current VBTS. In addition, this review deeply explores the device design of VBTS, pointing out how different design strategies of devices affect performance parameters, providing scientific guidance for the selection, design, optimization, and practical application of VBTS.
Perspectives
I hope this article can assist researchers in quickly familiarizing themselves with the field of vision - based tactile sensors. It allows them to have an intuitive understanding of the current measurement capabilities of such sensors. Moreover, it can help researchers rapidly identify the specific aspects of device design that need improvement to develop vision - based tactile sensors meeting their requirements. Additionally, this article is expected to inspire researchers to explore the potential application fields of vision - based tactile sensors.
