1. A method comprising:
- detecting, while a mobile computing device (MCD) is in an identity-protected locked (IPL) state, an activation event triggered by a writing tool operated by a user; and
responsive to detecting the activation event, exiting at least one of a sleep mode or inactive state and enabling handwritten input via movement of the writing tool on a display while the MCD remains in the IPL state,wherein the exiting and enabling the handwritten input includes respectively;
switching the MCD from the at least one of the sleep mode or the inactive state to a lower-power state, and accepting the handwritten input while the MCD is in the lower-power state; and
displaying simultaneously, while in the lower-power state, both a first user interface for entering handwritten data in response to the handwritten input of the user with a second user interface for unlocking the mobile device in response to the user entering a pin code for verifying the identity of the user; and
switching the MCD from the IPL state to an unlocked state in response to the user entering the input pin code for verifying the identity of the user,wherein the switching to the unlocked state includes switching from the lower-power state to a fully-powered and functional active state.

Abstract
Embodiments of the present invention disclose a method and system for enabling instant handwriting input on a mobile computing device. According to one embodiment, while the mobile device is in an inactive state and identity-protected, an activation event associated with a writing tool operated by a user is detected. In response to the activation event, the mobile computing device is switched from the inactive state to a low power state in which the mobile computing device is configured to accept and store handwritten input while remaining identity-protected.

8. A mobile computing device (MCD) comprising:
-
a touch-enabled display; a sensor for detecting an activation event triggered by a writing tool; a processing unit configured to; receive the activation event from the sensor while the MCD is in an identity-protected locked (IPL) state, causing the MCD to, in response to the detection of the activation event, perform exiting at least one of a sleep mode or inactive state and enable handwritten input on the display while remaining in the IPL state, switch the MCD from the at least one of a sleep mode or the inactive state to a lower-power state, wherein the MCD accepts the handwritten input while the MCD is in the lower-power state; display simultaneously, while in the lower-power state, both a first user interface for entering the handwritten input of the user with a second user interface for unlocking the MCD in response to entering an input pincode verifying the identity of the user; and switch the MCD from the IPL state to an unlocked state in response to the user entering the input pin code for verifying the identity of the user, wherein the switch to the unlocked state includes switching from the lower-power state to a fully-powered and functional active state. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for providing instant handwritten input on a mobile computing device (MCD) having a touch-enabled display, the method comprising:
-
detecting an activation event by a pen-based stylus operated by a user while the MCD is in an identity-protected locked (IPL) state and password-protected; switching the MCD, in response to detecting the activation event, from at least one of a sleep mode or an inactive mode to a low power mode, wherein the low power mode powers the display and enable handwritten input while the MCD remains in the IPL state; displaying simultaneously, while in the low power mode, both a first user interface for entering the handwritten input of the user with a second user interface for unlocking the mobile device in response to the user entering an input pin code for verifying the identity of the user; accepting input while the MCD remains in the IPL state in the low power mode; and switching the MCD from the IPL state to an unlocked state in response to the user entering the input pin code for verifying the identity of the user, wherein the switch to the unlocked state includes switching from the low power mode to a fully-powered and functional active state. - View Dependent Claims (16)
