While WorldSense could be just about anything, the trademark filing states that it is related to computer hardware, computer software, and virtual reality headsets. As Android Police notes, computer hardware and software can be rather generic, but the mention of a VR headset is particularly interesting.
Of course it could simply be Google expanding upon its current VR efforts which comes in the form of Daydream, but this trademark filing and the recent rumors are rather coincidental. It’s actually rather interesting to hear about Google possibly planning a standalone VR headset, especially when we heard last year that Google had apparently given up on that project.
However since we’re not privy to the inner workings of Google and the company’s decisions, perhaps something changed. Either way we should find out soon enough so check back with us later in the day for more Google I/O details.
