Ease of use and low power consumption, two major difficulties that smart watches must overcome

Myriam Joire, the chief project evangelist of the smart watch brand Pebble, said that there are only two relatively large platforms in the field of smart watches, and there is room for improvement.

“In addition to Pebble and Moto 360, I don’t think there is any smart watch that looks good;” Joire said in a speech at the Wearable Tech Expo in the United States: “The wearable device is more than ever. Emphasizing personalization, you will want this type of device to reflect your own personal style, so a customized, eye-catching design is very important, considering the material, appearance and size."

While Pebble and Moto 360 with Android Wear platform are the best products in this market, these two smart watches still face the challenges of charging, display and practicality. Battery life is a big problem, such as Pebble's original The 130 mAm battery can only be used for one day and charging for 50 minutes, which makes the company less satisfied and is actively extending its battery life and accelerating charging time.

"Battery endurance is the key to a range of technologies. If you're building a wearable device, your hardware and software need to be very power efficient -- which means choosing the right display, processor, and wireless communication technology;" Joire pointed out. "In addition, it means that your operating system needs to be lightweight. Android and TIzen are not. They are Linux-based heavyweight operating systems. What you need is a real-time operating system that can be executed on the Cortex M3 or M4 core. ”

Joire said that another barrier to the popularity of wearable devices is charging; she believes that wireless charging will be a near-term alternative to Micro USB connectors that take up valuable space, and she also calls for wireless charging device suppliers. One of AT&T promotes the growth of the wearable device industry by supporting a single standard.

“What we are trying to do now is to call other vendors to support a standardized, waterproof and low-complexity connector;” Joire said: “But it’s difficult to make a watch that is waterproof and equipped with wireless charging, mainly because of the coil. size of."

Smart watches -- and most mobile terminals -- have the battery life, the biggest consumer is the display; Joire pointed out that the display technology in the smart watch market can be said to let manufacturers "choose a way to die", see the user is Choose a monochrome display that is readable in daylight, or a high-resolution color display that consumes more power.

"There is no cure in this area, you have to choose one;" she said: "The wearable device will still be plagued by this problem for the next two years. Before it is resolved, there is only a compromise solution. We certainly want to A color, higher resolution display, but the display in daylight is difficult to beat the smartphone display."

Joire also predicts that future successful smart watch products will use communication technology beyond Bluetooth LE and traditional wireless routers, such as a smart personal area network system that can link various devices, equipped with wireless chips, size Only credit card size, and only charge once a month.

“Building a safe world around your body is a predictable future for wearable device connectivity;” she added, adding that users also need to trust wearable device manufacturers: “You must trust the tech world and put your profile Give it to us, this is the only way for us to predict what you want to do; background information is the key."

The establishment of background data and actual daily user stories is the key to making smart watches accepted by the public; Joire cited that Samsung's Galaxy Gear is very specialized in making early adopters become technology players: You need to make things simple, and most of the techniques I use today are not simple enough."

“If you want to be able to win customers outside of the early adopters, remember that those who buy smart watches need what they need most out of the box and bring value to their daily lives.” She concluded that the future Smart watches should focus on as few complex features as possible, adhering to ease of use and practicality out of the box.
