EPFL senior scientist Ricardo Chavarriaga said at a panel discussion at SDC 2018:
We are making new technologies which are more complex, but also more intelligent. At the same time, what do we need to do to provide accessible services to people who are unable to move?
The first step in selecting brain waves to control television is to collect brain signals through EEG.
Samsung and EPFL's solution is to combine environmental and brain scan indicators to build models and apply machine learning to allow users to choose through eye movements and brain waves.
To collect brainwave signals, users need to wear a head-mounted device with 64 sensors while staring at the Eye Tracker. It connects with computer and TV through mirror.
The current prototype uses eye tracking to make sure that the user has selected a program appropriately.The system will build user preferences.videoConfiguration files to provide content lists more easily in the future. However, the final choice depends on the user's eye tracking results.
Global neuroscientists have been working on ways to make digital interfaces for the brain. Although this technology is still in its early stages, it may one day replace touch screens and voice assistants in devices.
But Martin Kathriner, head of Swiss public relations at Samsung, said: Although the company's first prototype was also aimed at accessibility, it's too early to say when it will be available.
There are still many limitations in the current stage of hardware, especially the need to coat a gel on the user's head. It is hard for ordinary consumers to do it at home.The Samsung expert group told Cnet on SDC:
For us, this is an idea of barrier free use. As for whether it can become a standard for lazy couch on one day, it is not clear.
It is reported that Samsung initially considered using this technology on mobile phones.The reason why it's being tested on TV now is that its screen is bigger and most families are equipped with TV, which can serve as the center of smart home.
This is even more attractive for brain wave technology. Samsung plans to develop second prototypes in the first quarter of 2019, and then test it at a Swiss hospital.
