The discussion focuses on Voxon's interactive volumetric holograms, highlighting that while the term 'interactive' suggests user engagement, the technology currently allows limited interaction via a computer. Users express skepticism about the longevity of spinning displays due to their perceived lack of true interactivity. Comments mention the technical aspects, such as the LED matrix spinning at 15 RPS, leading to occasional jittery animations and visual limitations. There are mixed opinions on the practical applications of these displays, with some users hopeful about their potential in medical imaging and advertising, while others critique the resolution and sustainability of interest in such technology. Overall, the sentiment seems cautiously optimistic about future developments in volumetric display technology.
