If there is one thing the internet is good at, it's making things up. Anything you read online has to be taken with a pinch of salt, regardless of how accurate or reliable it seems, especially if there are no sources. A very good example is the story claiming that HTC is working on a thought-controlled headset. This definitely seems like the perfect example of realistic-seeming bullshit.
According to Portuguese site 4GNews the Google Glass-style headset comes with a camera and an eye-piece that is capable of reading brainwaves so you don't have to shout something like "Ok Google" whenever you want it to do something. The above image supposedly showcases the device in question alongside an HTC lab. But, as Slashgear points out, that's not an HTC lab at all, it's a stock photo of some physiological equipment.
Could HTC be working on its own smartglasses headset? It's a distinct possibility, but chances are that if it is in the works that the design is nowhere near finalised. Plus it probably won't look like one of the clunky Bluetooth headsets from 10 years ago.
