Kurzbeschreibung

Is human touch a magical connection, or can it also be simulated in virtual reality? Loneliness is a growing social problem that affects both mental and physical health. The necessary interpersonal connections are missing in our digitally networked world. Affective/emotional touch, such as gentle stroking, plays a central role in bonding between people. This form of touch activates C-tactile nerve fibers that send signals to the brain to release oxytocin, the “bonding hormone”. This promotes social closeness, lowers stress levels and creates a feeling of security. Until now, there has been a lack of technologies that can authentically simulate affective touch – the solution is Affina, a VR haptic jacket that simulates gentle touch with 128 tactile contact points, vibration motors, heat spirals and skin-like silicone. The technology is sewn between the layers of fabric, enabling flawless use and creating a free exterior design. Affina – a step towards a natural digital future.
