Glove Mode makes the Sony Xperia sola perfect for cold weather climates
cursor ring shows you where the touch is being registered by the screen and if you decide to take off the gloves, the screen will acknowledge it as a "normal" touch allowing you to continue without disabling the Glove Mode on the device.
For those in cold weather climates, where wearing gloves is common once the cold weather arrives, this could be the difference in doing more but answering a call while out and about. The technology involved is able to differentiate your finger inside the glove from the glove itself. Check out the video to see Glove Mode in action.
