Abstract
Provided are techniques for automatically correcting touchscreen errors. A first location input is received from a user touching a global touchscreen of a global device, where the first location input is a location relative to a display surface of the global touchscreen. It is determined that movement of the global device is different from movement of a local device. Motion information of the local device is retrieved. The first location input is corrected to a second location input based on the motion information. In response to the second location input, an operation is performed.
Claims18
A computer-implemented method, comprising operations for:
- discovering a plurality of local devices;
- receiving a user mark from each local device of the plurality of local devices;
- storing the user mark for each local device of the plurality of local devices;
- receiving a first location input from a user touching a global touchscreen of a global device of a moving vehicle, wherein the first location input is a location relative to a display surface of the global touchscreen and indicates a stored user mark;
- identifying a local device of the plurality of local devices that is associated with the stored user mark;
- determining movement of the global device of the moving vehicle that is different from movement of the local device, wherein the local device has a motion sensor, and wherein the local device is associated with the user;
- retrieving motion information from the motion sensor of the local device, wherein the motion information comprises acceleration and indicates movement of the user associated with the local device;
- correcting the first location input to a second location input at the global touchscreen of the global device of the moving vehicle based on the motion information from the motion sensor of the local device;
- and
- based on the second location input, performing an operation at the global device of the moving vehicle.
A computer program product, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code executable by at least one processor of a global device of a moving vehicle to perform operations for:
- discovering a plurality of local devices;
- receiving a user mark from each local device of the plurality of local devices;
- storing the user mark for each local device of the plurality of local devices;
- receiving a first location input from a user touching a global touchscreen of the global device of the moving vehicle, wherein the first location input is a location relative to a display surface of the global touchscreen and indicates a stored user mark;
- identifying a local device of the plurality of local devices that is associated with the stored user mark;
- determining movement of the global device of the moving vehicle that is different from movement of the local device, wherein the local device has a motion sensor, and wherein the local device is associated with the user;
- retrieving motion information from the motion sensor of the local device, wherein the motion information comprises acceleration and indicates movement of the user associated with the local device;
- correcting the first location input to a second location input at the global touchscreen of the global device of the moving vehicle based on the motion information from the motion sensor of the local device;
- and
- based on the second location input, performing an operation at the global device of the moving vehicle.
A computer system of a global device of a moving vehicle, comprising:
- one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices;
- and
- program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, to:
- discover a plurality of local devices;
- receive a user mark from each local device of the plurality of local devices;
- store the user mark for each local device of the plurality of local devices on the one or more computer-readable, tangible storage devices;
- receive a first location input from a user touching a global touchscreen of the global device of the moving vehicle, wherein the first location input is a location relative to a display surface of the global touchscreen and indicates a stored user mark;
- identify a local device of the plurality of local devices that is associated with the stored user mark;
- determine movement of the global device of the moving vehicle that is different from movement of the local device, wherein the local device has a motion sensor, and wherein the local device is associated with the user;
- retrieve motion information from the motion sensor of the local device, wherein the motion information comprises acceleration and indicates movement of the user associated with the local device;
- correct the first location input to a second location input at the global touchscreen of the global device of the moving vehicle based on the motion information from the motion sensor of the local device;
- and
- based on the second location input, perform an operation at the global device of the moving vehicle.
