Google Glass, Apple's Siri and now Leap Motion's gesture controller all point to a similar future, but are getting there by different roads.
Google Glass enables us to "wear" the internet, having it always on and within sight. Siri signals a future in which we may have Siri-enabled homes that allow us to access the web with simple voice prompts (and we can only hope a later version will understand that "find restaurant" does not mean "blind astronaut"). And now Leap Motion's gesture controller takes us one step closer to feeling like Tom Cruise in Minority Report, controlling technology through intuitive hand movements.
Glass still involves the presence of a physical object to access the web – ie, the glasses. This technology is pointing toward a cool future, but I don't think it's the final destination. My hunch is that future will be "touchless" – the web will surround us and require no physical objects or interaction – and will be accessed through a combination of voice and hand gestures. Of course, that is until we have a chip embedded at birth.
