At CES, Waiting for a Wrist Revolution The Wrist Revolution section of the International CES in Las Vegas is supposed to be at the forefront of smartwatches and wrist computers. Yet most of the gadgets on display do not seem ready for prime time. The smartwatches with color screens seem too big and bulky for most consumers to want to slap to their wrists. And most of the lighter watches use e-Ink, which, while low-power, displays only black-and-white images and is still very slow at refreshing. One gadget that did catch my eye was the FiLIP smartwatch, which is designed for children and parents. The FiLIP is a fun watch that comes in five colors and can wrap around a little wrist. It then allows parents to keep track of their children through a free downloadable smartphone app. Huw Medcraft, the company's chief operating officer, said the FiLIP allows up to five trusted contacts to communicate with a child using the location tracking, then talk to the child with a built-in two-way radio. "Parents can just pull out their smartphone and check where their child is at any time," he said. They can then use the two-way calling to tell them to come home. FiLIP is expected to be in stores in coming months and will sell for $200. The device uses AT&T for data, and it costs $10 per month to keep the smartwatch active.
