I apologize that this week’s posting was a bit delayed. I became somewhat busy with a new position. Check out http://www.w3.org/2010/03/ceo-pr.html for details.
We have been wandering through the 5-6 key constructs for secure natural communications. One of my key objectives is to enumerate research areas that require more effort to achieve our goal. Comments are invited on current status and research progress.
If the player’s semantic experience is one of higher-level semantics of unlimited breadth, the physical experience deals with a more specific set of modes of physical interaction that a user might have with the infrastructure. For each mode, the challenge is the same. The player has some means of physically expressing themselves. What is most “natural” depends on the player and depends on the application. But in any case, there are only a limited number of methods that are used.
Research problems related to the player’s physical experience
• Sensors. To obtain a greater degree of naturalness there will be many core sensors in the infrastructure. These will range from traffic sensors on highways to cameras to speech sensitive devices. Research is required to improve the cost, shrink the size, and blend into the environment.
• Enabling everything for secure natural communications. Further reductions in costs for RFID’s and GPS will include more items in the intelligent network and have their location trackable.
• Speech sensors. An important set of sensors. Microphones are available as part of the infrastructure so that people’s speech can be the primary input device of their intentions. Improved noise and echo cancellation for the overall system is required.
• Wearables. A key design point for small sensors; particularly speech capture is a wearable sensor. This requires research in nanotechnology to better embed this capability into garments.
• Video, gesture capture. This will enable a richer interpretation of the user’s intent, and a richer understanding of what is going on at target locations.
• Other methods. These would include different forms of keyboard, signing (for speech impaired), etc.
