Apple has filed to trademark the iWatch name in Japan, prompting increased speculation that the tech giant could be looking to soon move into the wearable devices market. Since the beginning of the year, rumours have been rife that Apple was developing an interactive watch, but there is still nothing concrete on what it would look like or what it might be capable of doing. In February, its reported an iWatch patent was filed in the US, detailing it was “an advanced wearable computer in the form of a bracelet that could double as a watch” which would allow users to “accomplish a number of different tasks including adjusting the order of a current playlist, or reviewing a list of recent phone calls”. Apple’s Tim Cook has previously said that “amazing new hardware” would be coming out in Autumn and throughout 2014. Unsurprisingly, however, the CEO has been vague on details.
