Their very small displays sometimes make smartphones difficult to operate.
In the future, a projector will help: if the cell phone is standing on a table, for instance, it can project a large-format display onto the table surface. The user will have the option of operating the smartphone via the projection function or from the display screen itself.
It‘s convenient to be able to show people vacation snapshots on a smartphone. But picture details are often hard to make out – the display is simply too small. A new LED projector could help: You position the smartphone in a small cradle on a coffee table,for instance, and it projects the image onto the table top: crisp, bright and DIN A4 size. If a user wants to zoom in on a portion of the picture, they can swipe the projection with their finger the same way they would swipe a display screen – the projected image can be controlled using the same principle as the display itself.
