Providing remote interactions with host device using a wireless device

Abstract

A wearable device that communicates with a host device can be used to initiate a communication functionality of the host device (e.g., telephone calls, text messages). The wearable device can obtain user input indicating a recipient of the communication and in some instances content for the communication and can provide an instruction to the host device. The host device can use the indicated recipient and content to initiate communication and where applicable to send the content. Recipients and/or content can be selected from predefined lists available on the wearable device.

What is claimed is: 
     
         1 . A wearable device, comprising:
 a memory configured to store computer-executable instructions;   a touch-screen display; and   a processor configured to access the memory and execute the computer-executable instructions to at least:
 detect that the wearable device is being worn by a user; 
 while the wearable device is in a first position with respect to the user:
 maintain a backlight of the touch-screen display in an off-state; and 
 determine, based at least in part on sensor data from one or more sensors of the wearable device, that the wearable device has moved from the first position with respect to the user to a second position with respect to the user; and 
 in accordance with a determination that the wearable device has moved from the first position to the second position, transition the backlight of the touch-screen display of the wearable device to an on-state. 
 
   
     
     
         2 . The wearable device of  claim 1 , wherein detecting that the wearable device is being worn by the user comprises receiving information, from at least a second sensor, indicative that the wearable device is being worn. 
     
     
         3 . The wearable device of  claim 1 , wherein the second position comprises a location wherein the touch-screen display is viewable by the user. 
     
     
         4 . The wearable device of  claim 1 , wherein the second position comprises a location wherein the touch-screen display is oriented towards the user. 
     
     
         5 . The wearable device of  claim 1 , wherein the first position comprises a location wherein the touch-screen display is not viewable by the user. 
     
     
         6 . The wearable device of  claim 1 , wherein the first position comprises a location wherein the touch-screen display is oriented away from the user. 
     
     
         7 . The wearable device of  claim 1 , wherein the one or more sensors comprises at least an accelerometer sensor. 
     
     
         8 . The wearable device of  claim 1 , wherein the one or more sensors comprises at least a gyroscope sensor. 
     
     
         9 . A method of operating a wearable device, comprising:
 at a device with one or more sensors and a touch-screen display:
 while the touch-screen display is in an inactive state:
 detecting, with the one or more sensors, a motion characteristic of a user moving the wearable device into a viewing position; and 
 in response to detecting the motion, activating the touch-screen display. 
 
   
     
     
         10 . The method of  claim 9 , further comprising detecting, the one or more sensors of the wearable device, that the wearable device is being worn by the user, the motion being detected only if the wearable device is being worn. 
     
     
         11 . The method of  claim 9 , wherein the one or more sensors comprises at least an accelerometer sensor. 
     
     
         12 . The method of  claim 9 , wherein the one or more sensors comprises at least a gyroscope sensor. 
     
     
         13 . The method of  claim 9 , wherein the active position comprises a location wherein the touch-screen display is oriented towards the user. 
     
     
         14 . The method of  claim 9 , wherein the wearable device is adapted to be worn on a user's wrist and wherein the motion characteristic of the user moving the wearable device into the viewing position corresponds to a wrist of the user being moved into a line of sight. 
     
     
         15 . A wearable device, comprising:
 a memory configured to store computer-executable instructions;   a touch-screen display; and   a processor configured to access the memory and execute the computer-executable instructions to at least:
 detect that a user is wearing the wearable device; 
 while the wearable device is in a first position with respect to the user:
 maintain a backlight of the touch-screen display in an off-state; and 
 detect an event that indicates that the user has moved the wearable device from a first position with respect to the user to a second position with respect to the user; and 
 transition a backlight of the touch-screen display of the wearable device to an on-state in accordance with the event. 
 
   
     
     
         16 . The wearable device of  claim 15 , wherein the event comprises the wearable device being rotated, on an arm of the user, from the first position to the second position. 
     
     
         17 . The wearable device of  claim 15 , wherein the first position comprises a location wherein the touch-screen display is not viewable by the user. 
     
     
         18 . The wearable device of  claim 15 , wherein the processor if further configured to execute the computer-executable instructions to at least determine that the wearable device is being worn by the user. 
     
     
         19 . The wearable device of  claim 18 , wherein the processor if further configured to execute the computer-executable instructions to only transition the backlight of the touchscreen to the on-state when the wearable device is being worn by the user. 
     
     
         20 . The wearable device of  claim 15 , wherein the second position comprises a location wherein the touch-screen display is not viewable by the user.
