A pointer/laser like remote using nothing but a Smartphone and built-in sensors like Accelerometer & Gyroscope.

https://sensei-mns3.onrender.com/ - Note : Due to Server Location, this might have some latency issues.

As you can see, I can point my Phone towards the screen and the Red Dot moves there as if the phone was a laser pointer. This is done with nothing but Sensors like Accelerometer, Gyroscope on the Device.

The Client utilizes the Generic Sensor API to access sensor data and then translates it into a position of pointer on your laptop/desktop screen. The data is transmitted in realtime using WebSockets through Socket-io and is drawn on the canvas.

As of writing this, the Generic Sensor API is only supported in Google Chrome v71+ and only on Android Devices. So the Client must be running on supported browser and device.

The Server consists of an Express-backed Node Server, customized to optionally serve using https that is required for the Generic Sensor API. (Configure Env Variable & generate Self Signed Certificate.)

Make sure to have a .env file configured with PORT (number) and HTTPS (Boolean).
