There are companies that have developed a tech that allows actual thought to control programs. There are companies that have developed eye tracking software. Why not integrate them together into a VR headset thought to use skills, eye tracking for veiw direction and controler for movement.
I'm not sure this is possible at the current technology levels we are at. Although the idea of using these two advances in a game sense would open doors for further research and more advanced technology. The brain activity during game play needs to be recorded as well as a side by side game play. Allowing further understanding of how the brain reacts to different situations
You are correct the idea of this is not exactly for the entertainment industry just yet. Although using that industry they can test and have 10 of thousands of testers Integrate eye tracking and thought control. A base skeleton version that allows analysis and utilization of both is all that is needed to start make a stock of these units sell them for 51% over PC to allow profit margin increase as well as grant continued R&D into both the program itself and the equipment upgrades just like phone companies do. This technology can be used in healthcare schooling as well as entertainment. The whole idea of Full dive VR is many decades from being probable. Sensation is one thing that is going to take the longest. Baby steps You crawl before you walk, you walk before you run, you run before you practice, you practice before you can play, you have to play before you can try out for tournaments, you have to go threw tournaments, to get to the championship you have to do championships, before you can get a title, You have to have a title to defend a title, you have to defend a title to become a legend. You must become a legend before you will be remembered.
The fact is there's always a next level to learn. The levels in between time line events bring more details about the legends. We have blizzard wild card and several other MMORPG game companies. That specializes in virtual environment. The building blocks are here we just need to put them together to find out what more we need to learn to get to a goal such as sensation replication inside a virtual environment Virtual reality.
