Morton Heilig wrote in the 1950s of an "Experience Theatre" that could encompass all the senses in an effective manner, thus drawing the viewer into the onscreen activity. He built a prototype of his vision dubbed the Sensorama in 1962, along with five short films to be displayed in it while engaging multiple senses (sight, sound, smell, and touch). Predating digital computing, the Sensorama was a mechanical device. Heilig also developed what he referred to as the "Telesphere Mask" (patented in 1960). The patent application described the device as "a telescopic television apparatus for individual use...The spectator is given a complete sensation of reality, i.e. moving three dimensional images which may be in colour, with 100% peripheral vision, binaural sound, scents and air breezes." https://www.youtube.com/watch?v=wczdECcwRw0&t=1s

Many other companies are developing Virtual Reality headsets and other peripherals. Upcoming hardware includes the GenBasic Quad HD, StarVR StarOne, Vrgineers XTAL and Pansonite VR Headset. As more and better hardware hits the market, it will continue to power a growing ecosystem of hardware manufacturers, software developers, and content providers.
Leap Motion has been around for a while but now it's got a new lease of life as a VR peripheral compatible with both the Rift and HTC Vive. It attaches with an add-on mounted to the front of the headset and adds hand gesture controls to your virtual reality gaming. It's super precise, tracking each finger – the question is, how precise are your dumb human hands? https://www.youtube.com/watch?v=nEi6u2lAYHg&t=1s

The Fove setup is an 5.7-inch, 1440p display; a 100+ degree field of view; 70fps frame rate; and eye-tracking measured at 120fps. With the redesigned developer kit, gone are the big side panels and quite a lot of the heft of the last prototype design. The company promises the new model offers "dramatically reduced weight, size and overall wearability, as well as better production efficiency." You might have to wait a bit though – Fove hasn't confirmed plans for the consumer version just yet. https://www.youtube.com/watch?v=sPyAQQklc1s&t=1s
