Google Dropped a Major Hint About its Next Big Product

Google Cardboard, the tech giant's low-cost virtual reality product, is going to be getting some big upgrades this year — and the new features likely won't be made of cardboard, according to Gizmodo.

The idea of Google Cardboard, which is literally made of cardboard, is that it can cheaply turn a smartphone into a virtual reality set. The product was announced at last year's Google (goog) I/O event. This year's event is where Clay Bavor, Google's product management and user experience chief for Gmail, Google Drive, and Google Apps, says the new features will be announced.

Gizmodo notes that some of the limitations of the original Google Cardboard — for instance, the lack of a head strap and the limited vision field — could be fixed in upcoming versions.
