| **Team members:** - Qing Wang(qingw3) - Diana Long (aslong2) - Joseph Cho(hyunjae4) **Problem:** For all commercial VR headsets, Meta Oculus Quest, Apple Vision Pro, HTC Vive, etc., hand gesture control is necessary for people to interact with the virtual world. However, for people with disabilities, those actions may not be possible. With the ever-growing use of virtual reality in both commercial and business use, a solution to allow these people to access and use VR is needed. Although motion tracking technology is already available in the market, they tend to be expensive. **Solution:** By creating a device that can track your leg movement, Virtual Reality controllers for those who are impaired in their arms or hands are possible to make. We shall design a motion tracker that consists of cheaper parts that will allow the user’s leg to be registered as a motion digitally, allowing for more affordable controllers to exist using technology similar to the current VR controllers. We will be using cameras to track the movement of the foot, as currently most motion tracking technology uses very high end cameras. We will be cutting costs by using cheaper cameras with a lower framerate but maximizing their usage. We will also be using accelerometers that will be attached on the user’s legs. Using the data these sensors collect, we can perform sensor fusion which will allow our device to track motion as if it was using a higher framerate camera. **Subsystems:** The subsystems of our device are the individual working components: the cameras, the casing, internals, and a PCB. - The cameras will be 30 fps, as this will allow us to design an efficient system for less money. This subsystem is where a lot of our cost reduction comes from as well, as tracking typically uses cameras with a much higher framerate. - The casing will be made of material that is sturdy, such as plastic, but also has padding to be comfortable on the user’s leg, like a cloth. This will allow for safe transportation of the internals and ease of use. - The internals will consist of an accelerometer, which will also track acceleration data of the user’s legs. - The data from the two sensors will be received by a PCB which will then combine the data through sensor fusion which will make our device perform as if we’re using a single tracking device. `https://www.udacity.com/blog/2021/01/how-sensor-fusion-works.html ` **Criterion For Success:** The criterion for success of this project is how much the tracking system could track the movement of legs. Each subsystem is individually testable, and can each be their own criterion. If a subsystem works individually, then it is considered a success, as it will work even when combined with other subsystems. Another criterion is the low cost of our product. If our product is not affordable by the public, then it will not have accomplished its goal. Furthermore, reliability is also important for extended use of our device and ease of use in any interior building. We will test if this system is reliable under most conditions, such as low light, room scale spaces, and sunlight interference. If the test succeeds, then our product will be accessible and functional to our target audience, as well as it being simple to utilize from a consumer’s perspective. If these conditions are met, then our project will be a success. |
