Do you have a plans to use thermal energy or something based on movement? I would like to blow a whistle or to do something with sculls to rotate some generator.
While a mouthpad seems slighly superior to an eye tracker, the real benefit lies in having more alternatives in my opinion. So you can use your tongue when your eyes are tired and your eyes when your tongue is tired.
As you mention, the MouthPad^ would serve as an awesome tool in tandem with gaze-based cursor control. I’d like to point out that there are also other interface combinations that could work well, too. For example, we have tested using our device in tandem with voice-assistant systems and found preliminary success as our device does not prevent speech. In the end, everyone has different needs and preferences, and each interface has their quirks, so we aim to create a better option by leveraging the power of the tongue (comprised of 8 different muscles, and intrinsically dexterous).
I would certainly be interested in the device purely from a keeping-both-hands-on-the-keyboard perspective.
Although our promotional video features people with quadriplegia, the MouthPad^ is designed for everyone and anyone interested in using their tongue and mouth to control their personal devices. We believe strongly in universal design, and how designing for extremes can create an improved experience for all users, and this has led us to work closely with the disability community. A classic example of the benefits of universal design can be seen in curb cuts, which were initially built into our sidewalks to help accommodate the needs of people living with mobility issues, but ended up providing value to many other groups, such as mothers with strollers, workers with carts, travelers with luggage, runners, skateboarders, etc.
5 hours of active use with no ability to change the battery is a shit, let's be honest. It will be 4 hours after 100 full recharges, you know this process. Also Bluetooth HID devices will never be acceptable for shooters while non-Bluetooth tongue controller may be a pivot point in cyber-sport industry because of less lag between the brain and the HID.
One example is asking a voice assistant to open “today’s news”, and then using the MouthPad^ to navigate through the options and select the desired link, which is captured briefly in our promotional video (a scene where Krystina is controlling her smart phone). Another example that can be found in our video is when Rocky NoHands uses his MouthPad^ to call his girlfriend, during which he is able to speak with ease. Of course, results may vary, but we have found all our test users are able to speak just fine so far.
