Most of the considerable inventions in Personal Computers were developped in the last decades. These improvements became vital elements of our world and work. They serve many different purposes and are used more and more in any activites in our everyday life. Therefore requirements are continuously changing, but productivity, reliability and effective ergonomic design of human - PC relation are still essential in designing any new devices.
Mouse is one of the first input device for computers. Despite the fact that its design has been changing many times, it has retained its original function: the pointing function. Accelerometers are becoming smaller and smaller thanks to the new improvements in electronics. Making use of these accelerometers in computer pointing devices – instead of the LEDs or previously used balls - offers new opportunities to explore or new advantages to add. Mouse designed with accelerometer can be used on any surface, even on a glass table. As it does not require any physical connection with its environment – except the sign wires – it can be designed in a completely enclosed form based on any specific requirements.
The aim of my work is to create a device which works on the above stated way and connects to the computer via USB-port. I reviewed the different types of accelerometers, the USB and USB-HID protocols in my thesis. After the reviewing these I designed the hardver and had it produced. Following the hardver production I developed the software for both the device and the PC, and implemented them. I started to test the device to make sure that the it was working appropriately - meeting the requirements which were stated in the beginning of the work -. I was making notes of these steps during my work and these are showed in details in the documentation part of the thesis.
