Company officials said the Rift headset will come with a stand-alone sensor that will sit on users' desks. That sensor will track users' head movements as they are wearing the device and their hands when they use the Touch sensors.

But the company held off on announcing many of the details that will be crucial to its success. Oculus has not yet said precisely how much the Rift will cost, which retailers will carry it, when exactly it will be hit store shelves, or how many games will be available when it launches.
Oculus officials said they plan to release more information about the device at the company's Connect conference in September.

The number and diversity of games available for the Rift could be a big potential trouble spot. Oculus only demonstrated three games at the event Thursday, none of which represents a blockbuster title like "Halo" or "Call of Duty." Although one of the games shown is being produced by Insomniac Games, the makers of the "Resistance" series of games, Oculus did not show off any games from any of the major game companies, like Electronic Arts or Activision.

?The success of new game systems is frequently determined by the number and range of games available for them. Fledgling systems can often suffer from a chicken-and-egg type scenario: consumers won't buy them until more games are available, while developers won't create games for them until a significant number of units are in consumers' hands.

There is a wide range of potential applications for virtual reality devices from entertainment to exercise and shopping. This is an emerging technology which has been evolving for a long time but is only now reaching commercial scale. 

Three years ago Bloomingdales installed Facecake’s virtual dressing room and Swivel technology which has not yet gained widespread traction.   The virtual reality retail application pioneered by Context Solutions still has a long way to go if it is to represent an interactive product.  This article by Heather Somerville also from the San Jose Mercury News site dated 2012 is useful for context. 

With regard to the gaming potential for virtual reality, the joint venture between Valve’s Steam app and HTC is worthy of mention. Valve is a privately held company so it may not feature on the radar for many investors. However its online portal for purchasing and accessing games had 75 million users by 2014. HTC bounced today from its deep oversold level to indicate at least a near-term low.

Accenture is also mentioned in the above articles as a developer of apps and technology relating to commercialising virtual reality. The share remains in a reasonably consistent uptrend and a sustained move below the 200-day MA would be required to question medium-term potential for additional upside.
