Abstract
A method is provided. In some examples, the method includes receiving a first user input at processing circuitry. The method also includes determining, by the processing circuitry based on a signal from a radar sensor, movement of a user in a room after receiving the first user input. In addition, the method includes determining, by the processing circuitry, a first estimated location of a first wall in the room based on a first portion of the movement of the user. The method further includes determining, by the processing circuitry, a second estimated location of a second wall in the room based on a second portion of the movement of the user.
Claims20
A method comprising:
- receiving, by processing circuitry, a first user input;
- determining, by the processing circuitry based on a signal from a radar sensor, movement of a user in a room after receiving the first user input;
- determining, by the processing circuitry, a first estimated location of a first wall in the room based on a first portion of the movement of the user;
- determining, by the processing circuitry, a second estimated location of a second wall in the room based on a second portion of the movement of the user;
- generating a static point cloud of non-moving objects in the room;
- modifying at least one of the first estimated location and the second estimated location using the static point cloud;
- and
- modifying the static point cloud based on the movement of the user.
A device comprising:
- a radar sensor configured to sense movement of a user in a room;
- and
- processing circuitry configured to:
- receive a first user input;
- determine, based on a signal from the radar sensor, the movement of the user in the room after receiving the first user input;
- determine a first estimated location of a first wall in the room based on a first portion of the movement of the user;
- determine a second estimated location of a second wall in the room based on a second portion of the movement of the user;
- generate a static point cloud of non-moving objects in the room;
- modify at least one of the first estimated location and the second estimated location based on the static point cloud;
- and
- modify the static point cloud based on the movement of the user.
A non-transitory computer-readable medium having executable instructions stored thereon, configured to be executable by processing circuitry for causing the processing circuitry to:
- receive a first user input;
- determine, based on a signal from a radar sensor, movement of a user in a room after receiving the first user input;
- determine a first estimated location of a first wall in the room based on a first portion of the movement of the user;
- determine a second estimated location of a second wall in the room based on a second portion of the movement of the user;
- generate a static point cloud of non-moving objects in the room;
- modify at least one of the first estimated location and the second estimated location based on the static point cloud;
- and
- modify the static point cloud based on the movement of the user.
