Solution Description
This solution is designed to provide low cost gesture recognition functionality using a Time-of-Flight (ToF) ranging sensor and an STM32 microcontroller. It represents a highly robust and reliable alternative to camera imaging techniques, as ToF sensors do not present privacy issues or performance loss due to poor lighting or unreflective surfaces.
The sensor employed in this design is the VL53L5CX Time-of-Flight ranging sensor featuring a wide field of view and 8x8 multizone detection. The software provided for gesture regognition functionality runs on an STM32F401 MCU, which balances power consumption and processing performance and offers a substantial set of interfaces and integrated periferals.
The range of target applications is extremely wide. The solution can be easily integrated in home appliances like coffee machines, cooking plates, and ovens, in personal electronics devices like laptops, tablets, and AR/VR headsets, as well as other applications like vending machines, public screens, and lifts.
