3D Spatial Sensor

This project entitled 3D spatial sensor which is a sensor that is designed for sensing touch
coordinates in 3 dimensions for 3D application such as 3Dmodeling andhumancomputer interface.
The main idea of this project is to develop 3D sensor that can be used by everybody with minimal
learnability and cost.
3D sensor is important to this world because our real world is a 3 dimensions world hence
our interaction with computer has to be in 3 dimensions so that the real data can be inputted into the
computer for further processing. However, many of the sensors for human computer interaction is
limited to 2 dimensions such as keyboard, mouse and touch screen device, hence the real interaction
between human and computer is limited by those devices.
In this project, the development of 3D spatial sensors will be based on a novel method which
make used of 2 cameras for 2 different spatial planes and a computer to calculate and derived the
3Dcoordinates from boththe image frames from the 2 cameras. Froma single touch 3D spatial
sensor, additional efforts and resources will be used to develop a multiple touch 3D spatial sensors.
Lastly, multiple touch 3D spatial sensors will be incorporate into different applications to
demonstrate the abilities of these sensors. Hopefully the development of this device can benefit
human and enhance the experience ofhuman computer interaction.
