Google just published a new research paper that delves into the details of how tablet owners use their devices. Using diaries, in-home interviews and contextual inquiry observations, the company's researchers observed how 33 U.S. tablet users interact with their devices. Some of the results are pretty straightforward (tablets are primarily used for personal purposes and to play games and check email), while others were a bit more surprising. Just as many participants used their tablets in their beds as on their couches, for example, and a surprisingly large number of tablet owners use their devices while cooking.
