For most companies, the Consumer Electronics Show is about showcasing real devices, or devices that are in development but that will be launched at some point in the (near) future. Casio has chosen to take some time out of their schedule at this year’s show in Las Vegas to showcase a brand new conceptualized watch that, unlike many other Bluetooth-enabled watches, focuses more on saving power, while still delivering the features that people would expect from a device of this nature.
The Casio watch is, by and far, still just a concept that Casio is putting a lot of work in. With the Bluetooth Low Energy (BLE) technology inside, the watch is utilizing the new low-power-consumption version of the short-range wireless networking standard. The watch is able to power its normal usage through a single button-cell battery, which makes it possible for the BLE-fused watch to consume the same amount of power as a normal wristwatch, even with the extra features thrown in.
Casio is testing the technology now, knowing that the BLE-technology will be implemented in devices in the near future. And that means not just smartphones. No word on when Casio will be trying to get something like this out to market, but the company will be showing the device off at their booth at CES, so stay tuned.
CASIO DEVELOPS WATCH THAT COMMUNICATES WITH SMARTPHONES VIA BLUETOOTH® LOW ENERGY LINK
Prototype Features the Latest Wireless Technology with Very Low Power Consumption
LAS VEGAS, JANUARY 5, 2011 — Casio Computer Co., Ltd., announced today that it has developed a watch using Bluetooth® Low Energy (BLE) technology, the new low-power-consumption version of the short-range wireless networking standard*. A prototype of the watch, sharing a two-way data link with a smartphone, will be exhibited at Casio’s booth (#11006) at the International Consumer Electronics Show to be held at the Las Vegas Convention Center from January 6-9, 2011.
Casio has been redefining the wristwatch for years by applying the latest technologies. Now, Casio’s application of BLE positions the company to create new possibilities for the way people use their watches. Taking advantage of the low power consumption of BLE, the new watch powers wireless communication functions with a single, ordinary button-cell battery, and without consuming any more battery life than a conventional wristwatch. Users can wear it every day just like they normally do, without the hassle of recharging which is required by typical mobile devices. Battery life is estimated at approximately two years based on the prototype model, assuming that the Bluetooth wireless communication function is used for 12 hours per day.
Casio’s new prototype communicates with BLE-equipped smartphones, which will be available in the near future and will connect to networks of various kinds of devices. As the wireless link between smartphones and watches gains in adoption, and as the universe of smartphone applications continues to grow, Casio expects to see new possibilities for watches in everyday life.
Casio aims to produce its first Bluetooth Low Energy Watch in 2011. Meanwhile, Casio will call for partner companies to develop applications compatible with smartphones and other household devices in such areas as sports, health, home entertainment, security, and communication with family and friends.
Overview of Casio’s Prototype Bluetooth Low Energy Watch
§ Wireless communication is powered by the button-cell battery used in small devices and watches
§ Battery life with the communication functions is the same as previously released watches
§ The watch case measures a comfortable 53.4 (D) x 44.4 (W) x 12.8 (T) millimeters
§ The alert signal notifies the wearer of calls and e-mail messages arriving on the networked smartphone
§ Alarm and vibration functions of a smartphone can be activated using a watch button
§ A smartphone’s ring and vibration alerts can be stopped by tapping the watch
§ Accurate time information can be transmitted from a smartphone to the watch to ensure correct time
Casio’s demonstration of the Bluetooth Low Energy Watch uses a prototype of a Bluetooth Low Energy smartphone. The demonstration will be conducted at Casio’s Booth (#11006) at 2011 International CES, in cooperation with NEC Casio Mobile Communications.
