However, a team from the University of Chicago has developed an entirely different type of touch-sensitive display <a href=\"https:\/\/www.axlab.cs.uchicago.edu\/projects\/bloombeacon\" target=\"_blank\" rel=\"nofollow noopener\">that uses persistence-of-vision techniques.<\/a><\/p>\n<p>The project is called BloomBeacon. It consists of a pair of spinning arms to create a stable round display in mid-air. One arm is covered in LEDs, while the other is covered with capacitive pads for touch sensing purposes.\u00a0 The trick behind this device is evident in the name\u2014the device uses soft, flexible arms which are hinged and \u201cbloom\u201d upwards as the device spins up to speed. This makes it safe to physically interact with the spinning blades while they\u2019re in motion to create a touch-interactive display. The device can thus display user interface elements like buttons that the viewer can interact with by reaching out and touching them directly.<\/p>\n<p>Normally we\u2019d advise\u00a0not sticking your fingers in a rotating piece of machinery, but in this case, BloomBeacon was designed specifically to make this safe. Even sticking your fingers or hand right through the spinning arms won\u2019t cause injury.<\/p>\n<p>We\u2019ve featured some other cool POV projects over the years, <a href=\"https:\/\/hackaday.com\/2025\/11\/01\/volumetric-display-takes-a-straight-forward-and-backward-approach\/\" rel=\"nofollow noopener\" target=\"_blank\">like this neat volumetric display<\/a>.
