Controlling external things with ideas has always been a scene in science fiction or science fiction movies, but Boston startup Neuable has to turn it into reality. With Neuroable's technology, users can use their minds to control virtual reality (VR) games, freeing their hands.
So far, VR is still a new technology, so we don't know what the best way to interact with VR. The answer given by Boston startup Neurot is to use the brain to track brain waves and then use the results to control VR video games.
Neurable is a "brain-computer interface" technology developer focused on judging a person's intentions by "deciphering" brain activity. First, Neuroable uses a dry electrode (which does not require an electrode for conductive paste) to record brain activity through an electroencephalogram (EEG) and then uses software to analyze these signals to determine impending behavior (ie, brain intent).
Ramses Alcaide, co-founder and CEO of Neurable, said: "You really don't have to do anything. It's a subconscious reaction, it's really cool." Akade is a graduate student at the University of Michigan. , led the development of this technology.
Neurable completed $2 million in financing last December, led by Brian Shin, and investors such as Point Judith Capital, Loup Ventures and Kraft Group.
The hardware shown by Neurable looks like a ring of electrodes attached to a headband that can be used with the HTC Vive VR helmet. Unlike the HTC Vive, the Neuroable hardware device uses wireless technology to send data to the computer via Bluetooth.
Later this year, Neuroc will launch the corresponding software tools for game development. Neurable said that the company does not intend to develop its own hardware devices, but hopes that other companies will develop corresponding hardware devices to support the technology.
Akaide also said before: "Our main task is to develop software development tools, the long-term goal is to run brain activity decryption software on all hardware and software applications."
Some analysts say that Neurop may take a long process to succeed. So far, no technology has been able to replace or replace traditional mouse, keyboard or touch controls. The "brain machine interface" is inherently cumbersome, slow, and error prone. Coupled with the fact that VR technology is still in its infancy, Neurable's technology has a long way to go.
In fact, researchers have previously used EEG to track brain activity and look for specific signals that correspond to the user's next move. But Neurod says they have found ways to reduce noise and can use these signals faster.
According to Akeder, the core innovation of Neurod is a machine learning method that reduces processing latency and solves BCI (brain machine interface) signal noise problems, thereby improving data quality. In the demonstration of the "Skyrim" game, Arcade used brain activity to select one of the four spells, and then used brain activity to throw it to the enemy, everything seems smooth.
Before using the Neuroable system, users need to receive about 5 minutes of training. But for the first time, the next time you change a game or app, you no longer need to receive training. Fundamentally, Neurot uses VR technology to display different targets while recording brain activity. Then track the detected changes (from one target to the next different target) to determine what the user wants to do.
Jaime Pineda, a professor at the University of California, San Diego, said he is also very interested in the technology of Neurod, but it is difficult to quickly track and quickly resolve.
Pineda said: "In the game, you need to capture at the fastest speed, otherwise it will lose its appeal."
Neurable did not explain the accuracy of the technology, but Akede said that the previous version achieved an accuracy of about 85% in real-time brain activity. If you delay for one second, the accuracy is as high as 99%. Today, this technology has been further improved.
