Research on Brain-Computer Interface (BCI) technologies and applications has rapidly developed in recent years. However, most current research is still narrowly focused on either enhancing the accuracy of signal recognition or in operations diversity, and, as a result, BCI has not yet been widely used in applications that might benefit a general and diverse user population. In a not so distant future, upon maturity of the technology, it is perhaps inevitable that BCI systems will also be useful in the lives of ordinary people; and see differentiated BCI technologies, devices, and interfaces designed for different user groups and, ultimately, open to customization by individuals.
Mind Visualizations
Using a 16-channel EEG headset, I recorded the brainwaves of many people listening to the same music and visualized them with Javascript as 6 rectangles that change shape and color with frequency. The changes of the 3 rectangles on the left and right are affected by the activity intensity of different regions of the left and right brains. Even when we’re all listening to the same piece of music, people’s brain activity is completely different. We can use a dozen adjectives to describe a piece of music: calm, jumpy, graceful, smooth, etc. But words cannot express the real “thoughts” in our brains after all. However, by visualizing human brain activity through simple graphics, what is shown in the video is a portrait of the actual “thoughts” of the participants. Just as portraits can vividly describe a person’s posture and expression, these “portraits” of the human brain dynamically and intuitively demonstrate the unique thinking characteristics of each person.Mind Visualizations – On site documentation & Raw data
Shows the process I went through to collect data for Mind Visualizations and what its data looked like initially.Mind-control drone
I prototyped a brain-controlled drone using OpenBCI's brain-computer interface device and Tobii's eye tracker. Eye movements control the rotation of the camera's perspective of the drone, and brain waves are used to control the direction of the drone's movement. The drone simulation software used in the demo is DJI Flight Simulator.Control the future
A mock BCI product promotion video set when a BCI user is about to take the elevator but his hands are occupied by two bags full of items. He can use the brain-computer interface to remotely control the elevator buttons to call the elevator. This demonstrates the convenience of the BCI's control capabilities.Learning the future
A mock BCI product promotion video shows a basketball beginner who is having trouble learning basketball. Through the BCI's ability to implant thoughts into the brain, he is soon able to play basketball well.
