Ultrasound Technology Could Bring Real Smell Simulation to Virtual Reality
For decades, the technology industry has pushed toward one goal: creating truly immersive digital experiences that blur the line between the physical and virtual worlds. From high-resolution displays to spatial audio and increasingly sophisticated haptic feedback, the evolution of virtual reality (VR) has been relentless. Yet despite these advances, one critical sense has remained largely untouched—smell. The absence of olfactory input has been one of the most noticeable gaps in immersive systems. While users can see and hear virtual environments with astonishing realism, the inability to smell them creates a subtle but powerful disconnect. This limitation has prevented VR from … Read more
