Writer who bears the name Gadgeteer, recently revised project EyeWriter for News Design, design and technical aspects. The project is ongoing EyeWriter cooperation efforts in research, which was designed for people suffering from amyotrophic lateral sclerosis (ALS), more commonly known as Lou Gehrig's disease. ALS is a progressive and fatal neurodegenerative disease that is caused by degeneration of nerve cells in the central nervous system that control voluntary muscle movement. The disease often moves quickly through the body, from feet and moving up, or head and moving down, but the muscles responsible for eye movements are usually spared.

EyeWriter project is a low-cost eye monitoring device combined with custom software that allows artists with paralysis to use only their eyes. As part the Design News points out that the project is an attempt to address the gaps in the development of low-end systems for monitoring eye. As we have previously written Eye Tracking Update, many eye tracking systems are quite cost-prohibitive, and designed for larger companies with money and funding for replacement of expensive proprietary systems. As is the case for open source software and ambitious developers, many engineers and tinkerers are looking for the basic structure and mechanics of the eye tracking hardware to enable them to experiment and build on existing facilities. This must be done on the cheap, and there is certainly a difference in the development of eye tracking systems a feasible cost.

lists the various hardware components, including the IR sensitive digital camera without auto-iris, lens mount, the IR LED and various other wires and hardware reviewer was impressed, calling it "simple and straightforward." Software seems comes in two parts - one that interfaces with the camera to monitor eye, and a separate drawing software that works with the eye movements. Reviewer Notes However, it is not certain, the tracking software can be installed on your computer as a mouse, so that people with ALS to control entire computer with the eyes, not only drawing software. Overall Gadgeteer price of the product as slightly difficult to use, and notes that some simple production and assembly of a web camera is required to use. This software is probably applicable and works for great base for experimentation.

With new products like this, it appears that the difference between price and have an efficient and high quality product is still reduced. Hopefully, further experiments in the new year.
