Gesture-Based Remote Control

Soon you'll be able to simply point at your television and control it with hand gestures.


Soon you'll be able to simply point at your television and control it with hand gestures.We love our mice, really we do. Sometimes, however, such as when we're sitting on the couch watching a DVD on a laptop, or when we're working across the rooman MP3-playing PC, it just isn't convenient to drag a hockey puck and click on what we want. Attempts to replace the venerable mousewhether with voice recognition or brain-wave scannershave invariably failed. But an alternative is emerging.

What is it? Compared with the intricacies of voice recognition, gesture recognition is a fairly simple idea that is only now making its way into consumer electronics. The idea is to employ a camera (such as a laptop's Webcam) to watch the user and react to the person's hand signals. Holding your palm out flat would indicate "stop," for example, if you're playing a movie or a song. And waving a fist around in the air could double as a pointing system: You would just move your fist to the right to move the pointer right, and so on.
When is it coming? Gesture recognition systems are creeping onto the market now. Toshiba, a pioneer in this market, has at least one product out that supports an early version of the technology: the Qosmio G55 laptop, which can recognize gestures to control multimedia playback. The company is also experimenting with a TV version of the technology, which would watch for hand signals via a small camera atop the set. Based on my tests, though, the accuracy of these systems still needs a lot of work.
Gesture recognition is a neat way to pause the DVD on your laptop, but it probably remains a way offbeing sophisticated enough for broad adoption.the same, its successful development would excite tons of interestthe "can't find the remote" crowd. Expect to see gesture recognition technology make some great strides over the next few years, with inroads into mainstream markets by 2012.

Apple stores may get iPhone-connecting transmitters in Share Apple is likely to equip its retail stores with transmitters that connect to visitors' iPhones and provide messages based on the products of their interest.     The iBeacon transmitter system has been designed to enhance the shopping experience of people who visit the store. According to Cnet, the transmitters would connect to a user's iPhone and send messages as the user takes a look around products in the store, offering more product information or invitation to workshops. The report said that stores such as Nordstrom experimented with such a system before bringing in the wrath of customers who discovered they were being tracked as they wandered through the store.

1. Irrelevant Elements By far, the biggest issue I come across with new site launches is this: They use too many elements that bring no real value to the audience. In fact, these often just downgrade user experience considerably. There are too many crowded designs and too much text on one page. There are too many icons and photos. Does your site really need a search bar? Do you really need to show the tag cloud in your blog sidebar? Think hard. What are the 20% of elements that bring 80% of the results you're after? Start there. Always have a sound reason for adding new features, bells and whistles. Never add more stuff just because it seems "cool and hip." - Juha Liikala , Stripped Bare Media 2. Flash Intros Flash intros are annoying for the customer, take too long to load, don't work on Apple mobile devices and are not recognized by Google. It is best to avoid them entirely. - Josh Weiss , Bluegala 3. Photo Carousel A lot of sites stil

How noise-cancelling technology works for headphones    Bose pioneered the concept of noise-cancelling headphones way back in 1989 after more than 10 years of research. ET explains how this fascinating technology works. Noise cancellation in the car You may have experienced that some cars are quieter than others - this is because of the special attention paid to insulating materials (special laminated glass for example). However, there's only so much that passive noise isolation can accomplish inside the complicated acoustics of the car. That's why luxury carmakers have been implementing active noise cancellation for a quieter cabin. The same active noise cancelling technologies used in headphones can be easily implemented in a car. See image for details. How it works Simply put, active noise cancellation works by 'listening' to unwanted ambient sounds, and then producing a s
