What do you mean lack of interaction? I agree the experience is uncomfortable after some time. This was using the HTC Vive. I have used the smaller Rift device before though and that was miles better although the visual aspect was much lower in quality. I think once they make the hardware smaller, lighter and cheaper the novelty could have a larger commonplace in day-to-day.
