A Sci-Fi Aerial Display: This Touchscreen Floats in Midair
Markus Mierse · IEEE Spectrum · 2024
On a star base far far away, a dashing hero presses a but-ton on a control panel and a schematic appears in midair. Deftly touching her fingers to the ethe-real display, the hero shuts down an energy shield and moves on with her secret mission. If you've watched any science fiction, you're probably familiar with this kind of scenario. But what you may not know is that while star bases and energy shields are still beyond us, floating displays are not.
