SAN FRANCISCO, Calif. – Standards for making consumer gear more accessible, measuring wireless power and sending stereo 3-D information over Bluetooth will be among the many issues discussed with the Consumer Electronics Association convenes its annual Industry Forum here next week.
The CEA has started a working group to discuss standards for product accessibility. Staying ahead of draft legislation in Congress is a major driver of the effort.
Legislation already exists about how to handle accessibility for telephone and broadcast TV services. But the rise of voice over Internet Protocol and Web video is forcing lawmakers to revisit the meaning of accessibility to basic services.
"A lot of it is about a shift to services on the Net," said Brian Markwalter, vice president of standards and technology at the CEA. "New FCC rules may be needed," he said.
Meanwhile, a separate working group hopes to complete in November a standard for infrared signaling for stereo 3-D glasses. The group is now discussing whether it will try to set a standard for RF signaling, and Broadcom has proposed using Bluetooth.
Another new working group will define a standard for measuring the efficiency of wireless charging products. Several wireless charging products are shipping that use a variety of approaches, but consumers lack a way to gauge their effectiveness, Markwalter said.
The group may also try to set standards for wireless charging methods that do not require close alignment of the device and a charging pad.
The six-day CEA event will include a wide variety of standards group meetings and panel discussions. Topics range from digital TV interfaces to home networking, in-car electronics and the smart grid.

Wireless charging? what effective and convenient is it?

Hopefully they can settle some of the issues in advance so that we don't see another "VHS vs Beta" or "Blu-Ray vs HD DVD" debacle. Of course, some of these are probably already well on their way so it may be too little, too late.

Wireless charging (aka inductive charging) provides convenience to the users. It as well keeps users away from electric shock. I wonder what the efficiency is like. Has the efficiency been improved?

I saw some wireless charging products whereby users need to put the phone onto a holder. Maybe it is more useful when users can carry & use while charging at the same time?

I will hang out during some of the CEA sessions this week. If anyone has specific questions you'd like me to explore, let me know.

Eric Giler demos wireless electricity. MIT and WiTricity have been developing a commercial product that charges your cell phone wirelessly. Nokia is currently integrating this technology into some of their mobile phone models. You can watch the video on the technology and see a demonstration of it:

They had better hurry up on defining some standards for 3-D before the question becomes moot. I think that the bloom is wearing off that rose pretty quickly. The only way to salvage the technology might be to drive the cost down very quickly. Between this and the adoption curve for Blu-Ray one would think that consumers are finally getting smarter about waiting a bit instead of sheepishly plunking down big bucks for the latest shiny thing.

I'd love to know if power efficiency testing is going to standardized and published for wireless charging. I've seen numbers from 50% to 90% efficiency and nothing definitive. I can't see using a wireless charger if it's only 50% efficient.
