By using only a camera and some code, you can perform various actions just by waving around your hand. Below you can find some example applications of this concept. </p>

Prerequisites

Languages

• Kotlin

Libraries/Tools

• JDK
• OpenCV
• NirCmd

Getting Started (Software)

Building

This project uses the Gradle build tool.

Downloading NirCmd

<p align="justify"> NirCmd is used by the VolumeSlider demo to control system volume on Windows. As there are no released versions of TouchControl with this functionality, NirCmd is optional and only for developers who wish to work with this part of the code. You can download either the <a href="https://www.nirsoft.net/utils/nircmd-x64.zip">64 bit</a> or the <a href="https://www.nirsoft.net/utils/nircmd.zip">32 bit</a> version. </p>

Getting Started (Hardware)

Camera

<p align="justify"> Position a camera (rotated at 180 degrees) above a dark surface. The camera should remain stationary while using the program and the background should remain unchanged. A darker surface will lead to better detection. </p>

Operation

<p align="justify"> Move your finger (or any object) through the area covered by the camera. The program will detect the location of the object and perform an action depending on the Touchable object being used. </p>
