While the future of Google Glass is still coming into focus, one particular use case may be emerging as the platforms killer app: golf. The centuries-old game of whacking balls into tiny holes across large expanses of grass, while avoiding trees, bodies of water, and sand, is a lot more interesting with a tiny computer strapped to your face, says Luke Kerr-Dinnen over at Golf Digest. Kerr-Dinnen recently took Glass for an outing to a local New York golf course with GolfSight, an app that uses GPS to give you real time information of where you are to the hole, along with technical details for some 25,000 courses worldwide. Google might have thought the same thing, because GolfSight was one of the early apps to be shown off on Glass, ahead of the companys app-development kit at an event last month. Kerr-Dinnen notes that battery life and storage for clips of gameplay were both limited, and he still got some odd stares from other golfers.
