Samsung might be working on a smartwatch that uses your hand as a projection surface

You will agree with me that one of the biggest setbacks you face when using smartwatches comes during usage, trying to make use of its app or interacting with its user interface becomes tiring because the screen is small, such that most users just use them for a quick glace of information.

It seems Samsung has a solution to this, a recent patent filing (PDF) by the South Korean company reveals a new wearable that  features a small projector that projects/displays an extended screen on the back of a wearer’s hand.

According to the patent filing, the projector will feature a camera and other sensor that would detect where a user taps and interacts with the UI being displayed at the back of the wearers hand, additionally the device would be able to identify the shape and geometry of the wearer’s hand, this will enable it to adapt the projected interface to display properly on an uneven surface.

Here’s the information as seen in the abstract; “A wearable device that is configured to be worn on a body of a user hand and a control method thereof are provided. The wearable device includes an image projector configured to project a virtual user interface (UI) screen, a camera configured to capture an image, and a processor configured to detect a target area from the image captured  by the camera, control the image projector to project the virtual UI screen, which corresponds to at least one of a shape and a size of the target area, onto the target area, and perform a function corresponding to a user interaction that is input through the virtual UI screen.”

Although Samsung might not even develop such a device (as with most patents), but this concept could make smartwatches more interactive and serve more than just as an extension for a smartphone.


Samsung, founded by Lee Byung-chul in 1938, is a South Korean multinational conglomerate company headquartered in Samsung Town, Seoul. Samsung diversified into areas including food processing, textiles, insurance, securities and retail. Samsung entered the electronics industry in the late 1960s and the construction and shipbuilding industries in the mid-1970s.
