Samsung patents wearable projector device that turns your hand into a display

Patents Patents Patents, just the other day Sony did a Patent on contact lens camera that shoots photos in a blink and now Samsung a South Korean multinational conglomerate company headquartered in Samsung Town, Seoul has filed a patent on wearable Smartwatch with a projector device that turns your hand into a display. 
 We all know how much Smartwatches are actively gaining popularity among common gadget users and the only limitation that we come across while using the wearable is its small screen. The limited screen size hinders the use of the device to its fullest because a user's finger can be larger than a selection area on the screen, causing the user to accidentally select an incorrect icon or other displayed item, but it can’t really be made bigger or there won’t be any point of its existence. Will this feature overcome the screen size issue as it is explained in the patent?

This patent filed by Samsung with the US Patent and Trademark Office (USPTO) details a wearable device with an embedded projector capable of casting an interactive virtual display onto the wearer's hand, or any other surface. 

Further more the document describes the wearable device featuring not only a projector but also a camera and processor capable of mapping out the surface area of the wearer's hand and then projecting a UI within those boundaries. The device would also be capable of projecting an image up to the user's fingers, or alternatively down their arm. Users could then control the device from the projected UI. 

 As we can see in the prototype images, the concept would use wearer’s hand as a projection base. The additional space of the palm would be covered by extra app features such as dial pad and menu options. Even knuckles will be used as the projection base for extra app elements. 

The patent also extends to headsets, suggesting Samsung could also be eyeing up a use for the technology within virtual reality/augmented reality scenarios. It's an intuitive way of tackling the current foibles of wearable devices, which currently find themselves of limited use beyond being a fitness tracker or a secondary display for your smartphone. If Samsung follows through with its research, the company may help wearable tech find the wider audience it so sorely craves. Note that this patent was filed in the year 2014, but has been discovered recently.
