Information processing apparatus, control method, and recording medium

A non-transitory computer-readable recording medium storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• controlling a moving body detector to detect an approach of a moving body within a range of a first detection distance;
• restoring, upon detection of the approach of the moving body, an information processing apparatus to a first electric energy mode;
• detecting an operation of a user;
• storing history information indicating the approach of the moving body and history information indicating the operation of the user;
• computing a mean time based on the stored history information, the mean time being an average of a plurality of approach times, each approach time being a time between a time at which an approach of the moving body is detected and a time at which an operation of the user is detected;
• re-computing the first detection distance based on,
• the computed mean time,
• a restoration time required for restoring the information processing apparatus to the first electric energy mode, and
• the stored history information;
• and
• setting the re-computed first detection distance in the moving body detector,
• wherein the re-computing of the first detection distance includes,
• when a first proportion is greater than or equal to a threshold value, and the mean time is determined to be longer than the restoration time,
• reducing the first detection distance in the moving body detector, and
• when the first proportion is less than the threshold value, and the mean time is determined to be longer than the restoration time,
• increasing the first detection distance in the moving body detector,
• the first proportion being a proportion of records, with respect to a plurality of records included in the history information, that are first records,
• each first record being a record that indicates an absence of person detected and is preceded by a record that indicates a presence of a person detected.

A method for controlling an electric energy mode of a computer, the method comprising:

• detecting, by a moving body detector, an approach of a moving body within a range of a first detection distance;
• storing the detected approach of the moving body;
• restoring, upon detection of the approach of the moving body, the computer to a first electric energy mode;
• detecting an operation of a user;
• storing history information including the detected operation of the user;
• computing a mean time based on the stored history information, the mean time being an average of a plurality of approach times, each approach time being a time between a time at which an approach of the moving body is detected and a time at which an operation of the user is detected;
• re-computing the first detection distance based on,
• the computed mean time,
• a restoration time required for restoring the computer to the first electric energy mode, and
• the stored history information;
• and
• setting the re-computed first detection distance,
• wherein the re-computing of the first detection distance includes,
• when a first proportion is greater than or equal to a threshold value, and the mean time is determined to be longer than the restoration time,
• reducing the first detection distance in the moving body detector, and
• when the first proportion is less than the threshold value, and the mean time is determined to be longer than the restoration time,
• increasing the first detection distance in the moving body detector,
• the first proportion being a proportion of records, with respect to a plurality of records included in the history information, that are first records,
• each first record being a record that indicates an absence of person detected and is preceded by a record that indicates a presence of a person detected.
