These alliances aim to expand the Neural Band’s applications, from controlling car interfaces to aiding adaptive sports equipment like the TetraSki for paralyzed athletes.

Hands-On Impressions and User Feedback

Initial reviews paint a picture of promise tempered by realism. CNET describes the feature as enabling users to “scribble messages on your leg (or anywhere else),” though the reviewer notes they haven’t tested it personally. Early access users report varying accuracy, with the system excelling in controlled environments but struggling with rapid movements or distractions. On X, enthusiasts like VoodooDE VR have praised the innovation, calling it a “huge consumer innovation” while questioning the international delay.

Beyond handwriting, Meta introduced complementary features like a teleprompter mode, which displays notes or scripts on the glasses’ monocular display. This is particularly useful for public speakers or content creators, allowing them to maintain eye contact while referencing prepared text. Integration with Instagram Reels, as mentioned in Android Central, suggests broader social media applications, where users could compose captions or comments via neural inputs.

User sentiment on platforms like X reflects excitement mixed with skepticism. Posts from figures such as Brett Adcock highlight the band’s ability to control devices through simple gestures, drawing comparisons to more invasive technologies like Neuralink.
