Operation Method of handheld device

The following are all fantasies, unverified.

Nowadays, mobile phones (or other handheld devices) have many functions. In addition to software installed on them, there are often a bunch of icons. Now, they are usually displayed on pages or up or down.

I fantasized about one of the following operations:

Put all the icons on a large screen, and our handheld devices can only see some of them due to screen and resolution restrictions. (You can also zoom out the big screen on your phone, but it is not convenient to select an icon ). Just like viewing a map, you can drag the screen to the desired icon, zoom in or zoom out, and drag in at 360 degrees. Zoom out to view all the icons and locations of the icons you want to find. zoom in to the desired area and click the desired icon.

To view which part of the screen is selected, you do not need to slide the screen with your fingers. Another option is to move your mobile phone directly to view the icon at the corresponding position of the large screen.

What sensors are there in the general handheld devices? You can check the mobile devices. Then, move the handheld devices to the left to see the icon on the left.

This movement method can be imagined as two types: one is flat and the other is spherical. Can there be other shapes? I cannot think of it for the moment.
