Abstract
A wearable device includes: a touch screen; an acceleration sensor configured to generate an acceleration signal; an optical sensor using a light source and configured to generate a touch interrupt signal; and a control unit configured to detect a wearing state of the wearable device, the wearing state of the wearable device including a not-wearing state for the wearable device, a wrist wearing state, and a hand gripping state on the basis of the acceleration signal and the touch interrupt signal, and to execute a function corresponding to the wearing state of the wearable device.
Claims19
A wearable device comprising:
- a touch screen configured to display information;
- an acceleration sensor configured to generate an acceleration signal;
- an optical sensor comprising a light source and configured to generate a touch interrupt signal;
- and
- a control unit configured to:
- determine a wearing state of the wearable device based on the acceleration signal or the touch interrupt signal, the wearing state comprising a not-wearing state, a wrist-wearing state, or a hand-gripping state;
- and
- execute a function corresponding to the determined wearing state;
- display a first screen representing that the touch screen is turned off if the wearable device is in the not-wearing state,
- display a second screen representing a watch screen if the wearable device is in the wrist wearing state, and
- display a third screen including notification information if the wearable device is in the hand gripping state,
- wherein each of the first screen, the second screen and the third screen is a lock screen or a lock release screen,
- the lock screen is a screen for limiting an access of an application in the wearable device, and
- the lock release screen is a screen for allowing the access of the application in the wearable device.
A control method of a wearable device, the method comprising:
- determining a wearing state of the wearable device based on an acceleration signal or a touch interrupt signal, the wearing state comprising a not-wearing state, a wrist-wearing state, or a hand-gripping state;
- and
- executing a function corresponding to the determined wearing state,
- wherein the executing the function comprises
- displaying a first screen representing that the touch screen is turned off if the wearable device is in the not-wearing state,
- displaying a second screen representing a watch screen if the wearable device is in the wrist wearing state, and
- displaying a third screen including notification information if the wearable device is in the hand gripping state,
- wherein each of the first screen, the second screen and the third screen is a lock screen or a lock release screen,
- the lock screen is a screen for limiting an access of an application in the wearable device, and
- the lock release screen is a screen for allowing the access of the application in the wearable device.
