The method also works with a pencil-size wand, which can move the cursor when the user is not seated at the computer and up to about 30 feet away. A small key installed on the keyboard near the space bar allows the user to click on an object when the cursor is in position. In finger tracking, computer users wear a small ring near the tip of an index finger, the movement of which propels the cursor around the screen. “It’s not an efficient or natural way to do things,” he said. The impetus for the dot-tracking technology came from Johnston’s aversion to taking his hand from the keyboard to manipulate a mouse. “Now my head is the mouse.” Next came his nose. He then placed the dot on his forehead and began tilting his head. “See, now my finger is the mouse,” Johnston said. The cursor on the screen moved in concert.
Mouseless technology software#
“As you move the dot, the software moves the cursor.” Seated at a computer in his Seattle area office, he performed an impromptu demonstration, placing a small reflective dot on the end of his finger, then moving his finger in small arcs. “The computer tracks the reflective dot,” he said. Johnston then uses reflective dots – on a ring, wand or headmounted device – to provide a reference point for the computer. Inside the camera are light-emitting diodes, or LEDs, which bathe the area in front of the computer with infrared light. A tiny camera is mounted at the top of the keyboard, aimed at the user. The concept for the mouseless technology is relatively simple. “That collaboration is something we may continue, as we get more funding, to take this in new directions,” Johnston said. Johnston initially obtained a grant from the Washington Technology Center and researched the idea in collaboration with the UW’s Human Interface Technology Lab, where he used to run the lab’s Virtual Retinal Display project. “I show it to people and they get very excited.
“There are a lot of possibilities for this,” Johnston said. And then there are potential applications for virtual gaming.

The technology also makes computer presentations a breeze with the use of a remote wand, promises to nudge Web TV into the realm of truly convenient entertainment and eases computing for those with disabilities. In its place would be a ring that allows computer users to manipulate their cursor with the lift of a finger – and without taking their hands off the keyboard.
The former University of Washington researcher and founder of a new start-up company called Dot On has found a way to demouse home computers. He wants to get rid of the mouse, period. And that would be your first step to completion.Richard Johnston isn’t looking to build a better mousetrap. Look up OpenCV if you havnt already, download, build it, follow tutorials and start from there! Then I think you should aim to build an application that tracks white objects in the frame. I suggest taking this route first even if downscaling to a raspberry pi is possible in the future, it will introduce you to image processing, and at least you know that it CAN work, as there is a working example. Build an application on a laptop or desktop computer which has enough power for the image processing. The ideal solution for you would be to do exactly what this guy has done. The pi itself is still not powerful enough to perform real time image processing to a good level, however it's a possibility that it could work (my image processing was more complicated than processing a binary image and tracking dots).
I once did image processing with the raspberry pi. A more powerful Intel based device may have some potential for your project but I doubt it. This is not something a microcontroller such as the arduino can achieve. The method you posted in the video requires a lot of image processing to track the blobs. That being said I will say that what you want to achieve is not possible on only an arduino. The stack exchange requires that the poster make some effort to make progress in thier project before posting specific problems they are having.
Mouseless technology code#
No one is going to come here, post all the electrical schematics you need, all the code you need, and walk you through step by step.
