One major feature that Samsung has patented would allow users to interact with 3D images projected by the smart glasses, for example users can project keypads in mid-air to dial phone numbers, punch in messages and perhaps even take a shot at a virtual piano keyboard. A recent patent application by Samsung explains that the smart glasses will use two cameras to project 3D images in mid-air so as to create a virtual input interface, this will allow users to interact with apps and services the way they would on a smartphone.
Samsung engineers have also come up with a way to visualize how users could project augmented reality objects on physical objects and then use them to interact with apps and services. For example if a user wants to make a phone call or send a message they can project the keypad on their hand, held just 10cm away from the glasses, and then use the fingers of the other hand to dial in the number and make the phone call. The same technique can be used for sending messages and even playing keys on a virtual piano keyboard. This technology only exists in patents right now and it's not known for sure if and when Samsung intends to come out with its own smart glasses, but when it does and if they have this feature, they're going to be so much more appealing than Google Glass.
