In addition to 5G, phones are now available with the option of texting by thought power alone.* This is achieved by a combination of eye-tracking technology and a sensor-mounted headset worn by the user. The headset contains a brain-machine interface which detects electrical brain waves and converts them into digital signals, then displays the resulting letters on-screen.*
Some high-end models can be used with glasses or visors featuring displays built into their lenses. This enables completely hands-free texting, creating a form of virtual telepathy. The process is rather slow at this stage, requiring a high degree of mental concentration. It is more of a novelty for now. However, advances in the coming years will enable smooth and fast interactions, revolutionising the world of communication.
