Abstract
Methods and systems for improving signal reception and call quality by detecting a user's handedness of holding a mobile device during a call are described. Motion data of the mobile device can be collected by one or more motion sensor. A screen tilt angle can be determined and compared with a threshold tilt angle. A screen swivel angle can be determined and compared with a threshold swivel angle. A call handedness can be determined based on the screen swivel angle. One or more parameters of an antenna can be adjusted based on the call handedness.
Claims19
A method for improving signal reception and call quality of a mobile device while a user is holding the mobile device during a call, the method comprising:
- collecting, by one or more motion sensors of the mobile device, motion data of the mobile device;
- determining, by a processor circuit of the mobile device, one or more constraints are met based on the motion data;
- determining, by the processor circuit , a screen swivel angle of the mobile device based on the motion data;
- determining, by the processor circuit, a handedness of the user while holding the mobile device based on the determined screen swivel angle;
- and
- adjusting, by the processor circuit, one or more parameters of an antenna of the mobile device based on the determined handedness of the user, wherein the one or more parameters comprise frequency, wherein the adjustment improves the signal reception and call quality of the mobile device.
A system for improving signal reception and call quality of a mobile device while a user is holding the mobile device during a call, the system comprising:
- an antenna;
- one or more motion sensors configured to collect motion data of the mobile device;
- and
- a processor circuit coupled to the antenna and the one or more motion sensors, and configured to execute instructions causing the processor circuit to:
- determine one or more constraints are met based on the motion data;
- determine a screen swivel angle of the mobile device based on the motion data;
- determine a handedness of the user while holding the mobile device based on the determined screen swivel angle;
- and
- adjust one or more parameters of the antenna based on the determined handedness of the user, wherein the one or more parameters comprise frequency, wherein the adjustment improves the signal reception and call quality of the mobile device.
A non-transitory computer-readable medium storing program instructions that are executable to:
- collect, by one or more motion sensors of a mobile device, motion data of the mobile device;
- determine, by a processor circuit of the mobile device, one or more constraints are met based on the motion data;
- determine, by the processor circuit, a screen swivel angle of the mobile device based on the motion data;
- determine, by the processor circuit, a handedness of the user while holding the mobile device based on the determined screen swivel angle;
- and
- adjust, by the processor circuit, one or more parameters of an antenna of the mobile device based on the determined handedness of the user, wherein the one or more parameters comprise frequency, wherein the adjustment improves the signal reception and call quality of the mobile device.
