Virtual reality technology has introduced the aspect of comfort into gaming, and the Vive N Chill from gaming peripheral company RedRotor is a device designed specifically to address that new issue. The Vive N Chill consists of two fans that attach to the top of an HTC Vive and blow towards the wearer, keeping them cool as stress and action mount during a vigorous VR session.
With games in the past, real-world experience was essentially irrelevant. Game-designers (both hardware and software) were almost exclusively concerned with how users engaged with the virtual world of the game; the assumption was that these gamers would create their own comfortable experience in their living rooms or gaming spaces. Since VR requires a relatively bulky headset, user comfort is a completely new problem that the Vive N Chill helps with.
