CPE111 Project "Virtual Keyboard By Leap Motion": 0) Create blog, Study overview Leap Motion and Test some experiment.

At the beginning, my group have interested in Leap Motion. Leap Motion is a infrared sensor and input device of computer which acting like mouse. I and my team learn have learned about Leap Motion. Nevertheless, we didn't have any idea to invent something that's creative by using Leap Motion sensor.

After that, Peak(Phuwadon) have idea which using Leap to virtualize keyboard in air at first. Jame(Siwat) told that it was difficult to do that and your hands felt tired because two hand must be contracted in air. James(Saran) offered that we should rotate and flip this device by face sensor to user. but it had obstacle about XYZ axis to detect finger and hand in our project and Leap Motion was designed to do like this.

Thus, we concluded "We would use some transparent sheet to make two hands feel comfortable". Next, Jame requested transparent sheet from TA (P'Jet). Thank to P'Jet. He gave me a transparent acrylic sheet. My teammate and I brought it to test. Is infrared from Leap Motion can detect hands by having transparent sheet ?

My group found that "It's work !". Leap Motion can detect hands practically. We have designed Virtual Keyboard by using physical technic such as pressing ,holding and releasing to sheet. There are many programming languages to develop project such as C++, Objective-C, Python, JavaScript but we chose Java. As a result Java is popular and Java can run all platforms. Java will have advantage in the future. We have learned Java and Leap Motion SDK documentation to invent Virtual Keyboard.
