Samsung patents projector that turns projected images into touch screens

Patent drawing
Patent drawing from the official filing.

Samsung describes a system where a projector connects to a computer or tablet to display its screen. The projector detects when a user touches the projected image and sends that touch data back to the connected device, allowing the user to interact with the large image as if it were a standard touchscreen.

Why it mattersThis could make large projected displays easier to use for presentations or interactive media by removing the need for separate touch sensors on the screen.

In the filing’s own words

A projector may: determine whether the projector is communicatively connected to a display device; and, if the projector is communicatively connected to the display device, receive, from the display device, a third output screen including at least one user interface object, project an image of the third output screen, obtain a touch input with respect to the third output screen, and transmit third control data corresponding to user touch input to the display device.

What exactly they claim (claim 1)

1. A display device comprising: a display; a communication interface comprising communication circuitry configured to perform data communication with a projector; memory storing at least one instruction; and at least one processor, comprising processing circuitry, electrically connected to the memory and individually and/or collectively, configured to execute the at least one instruction, to cause the display device to: determine whether a communication connection to the projector is established using the communication interface; and based on the communication connection to the projector being established: determine whether at least one user interface object is included in a first output screen; based on the at least one user interface object being included in the first output screen, generate a second output screen except for the at least one user interface object from the first output screen; and display the second output screen.
