Event technology is expanding at a rapid pace, and while attendees are looking for worthwhile, in-person experiences, organizers are looking to host more memorable and unique events. This has opened the market for experiential audiovisual technology, where the conference, event, or tradeshow immerses the audience outside of the traditional format of booth posters and lecture halls. Some of the methods of doing this are through augmented reality (AR) or extended reality (xR). AR typically uses peripherals such as smart goggles to engage the viewer in a fully encapsulating 3D space, whereas xR uses unique and innovative technology to fill the visual and/or auditory field with an experience.
HyperVSN is a company offering an xR display product that simulates a 3D holographic image or video, producing stunning results. This technology has matured rapidly and has captured the imaginations of several conference and tradeshow attendees across the world. HyperVSN uses a biological phenomenon known as Persistence of Vision (PoV) that causes the brain to fill in what it is not seeing. Taking advantage of this, HyperVSN features a rapidly rotating fan (or for larger displays, an array of fans), with each fan blade having a line of LEDs. The software controlling the fans is able to determine where each LED will be at any given time, as well as its position in relation to the other LEDs, and is able to have it shine with a specific colour.
As these fans spin very rapidly, this appears as a solid canvas to the human eye, and the subsequent LED flashing makes it appear like a regular pixel for a digital image or video, making it appear that there is a holographic image floating in mid-air.
The rapid spinning of the fans and the subsequent flashing of the LED appear as a solid canvas to the human eye, imitating a regular pixel from a digital image or video. This gives the optical illusion of a holographic image floating in mid-air.
Depending on the background used behind the fans, the image can appear as a floating vignette, or as a high-definition holographic projection. As it does take advantage of some brain trickery, the darker the background, the clearer the image will appear, but the lighter the background is, the more the 3D holographic effect is pronounced. The technology is also easy to set up, as the fans and their supporting stands are lightweight, with minimal cabling, making this a very efficient, space-saving and power-effective display technology.
Due to the setup and ease-of-use of this technology, the HyperVSN technology can be used in a variety of cases, as outlined below:
Tradeshows
The product can be set up in tradeshow booths or areas of varying sizes. The displays can be expanded by adding as many fans as needed to create the canvas size you require and can be used to show off advertising, sponsorship, product showcases, or even interactive elements when paired with a camera and green screen. A common use is to set a single fan high above the crowd to display holographic logos to attract tradeshow floor attendees.
Plenary & Keynote Sessions
The display can be set up on the stage of a lecture theatre to project unique holographic backdrops, as well as to project a pre-recorded or remote speaker from a studio anywhere in the world. The 3D effect can present a sense of depth and realism, making the talk more engaging.
Product Showcase Room
When used in a light-controlled space or against a dark background, the hologram is very well-defined and can be used to showcase product demos in 3D, presenting an opportunity for a very immersive and memorable experience for attendees who stop by the space.
In Conclusion
PoV technology has evolved from being a gimmicky trick into a mature technology that is able to display highly-defined graphics. Paired with an imaginative content creation team, the use of the HyperVSN holographic display can truly elevate your tradeshow, conference or overall event.
