While LG is slated to soon launch the LG 3G smartwatch, Apple Watch and Qualcomm Toq Smartwatch are already in the market. Sony is also working on the 2nd variant of its smartwatch after the initial success of its wearable tech device. It might sound enthusiastic in the first instance but wearable tech devices do have their limitations. Let’s get an overview of the technology behind these devices to understand things in a better perspective. Battery life of the smartwatch Limited battery life is one of the biggest concerns in wearable technology devices. The Galaxy Gear smartwatch from Samsung will last a day with regular use. If used frequently, the same might run out soon enough. Google Glass battery can run down in 1.5-2 hours if video shooting is done. Removing a wearable device frequently for charging can be irritating lot and can take away the charm soon enough. Size matters Size is another concern which wearable tech devise manufacturers have to address. A normal sized device will be difficult to operate as numerous applications exist on the same. Increasing the size can make the average user turn away as it gives a bulkier appearance. A thin line between aesthetic designing and technological compatibility needs to be drawn to address this issue effectively. Value addition a far cry Smaller screen, poor resolution and frequent recharging are only some of the evident drawbacks present in wearable tech devices. Price is another constrain as a smartphone with bigger screen size and enhanced resolution can be bought for the cost of a wearable tech device. Undoubtedly, the future belongs to technology and with innovative products as wearable tech devices becoming a reality, the prospects are improving. However, it is still a mixed bag and tech device manufacturers will have to work overtime to get rid of the shortcomings.
