VR Interactive Car for Disable People
Brief Discription
After witnessing infantile autism(ASDs) among disable people as they cannot easily get in touch with lots of entertainment, I decided to change this situation by developing new ways for game accessing. I designed a low-cost telepresence platform that lets users steer a real ESP32/L298 car from a simple Minecraft scene. Virtual buttons become compact 5-bit commands—11111 (forward), 01100 (left), 01000 (right), 00000 (stop)—sent via MQTT or ESP-Now to the car’s controller. Minecraft chat and coordinates provide friendly, real-time feedback, so users can practice virtually before moving in the real world. The modular design supports accessible home navigation, caregiver tele-assist, and classroom demos.

Our glooves based gesture detection is performed on an integrated system placed in the back of the glove, powered from a flat Li-Po battery integrated under the wrist. Shown are four different gestures (out of the 22 we consider in the evaluation) including those that for most gloves are not easily distinguishable from each other.

Connect Vehicle with Minecraft and Redstone Circuits
By connecting with Minecraft redstone circuits, the liquid-metal glove can not only control the car independently through different hand gestures, but can also link to virtual games, allowing even patients with limited hand mobility to enjoy gaming and experience the appeal of virtual reality interaction.
