Abstract
This walking index calculation device comprises: a waveform generation unit that uses sensor data related to foot movement acquired by a sensor installed in footwear to generate a walking waveform in order to calculate the toe clearance while walking in daily life; a detection unit that detects, from the walking waveform, the timing at which the toe clearance is minimized; and a calculation unit that uses walking parameters at the timing when the toe clearance is minimized to calculate the minimum value of the toe clearance.
Claims10
A walking index calculation device comprising:
- at least one memory storing instructions;
- and
- at least one processor connected to the at least one memory and configured to execute the instructions to:
- generate a walking waveform by using sensor data regarding motion of a foot acquired by a sensor installed in footwear;
- detect a timing at which a clearance of a toe is minimized from the walking waveform;
- and
- calculate a minimum value of the clearance of the toe by using a walking parameter at the timing at which the clearance of the toe is minimized.
A walking index calculation method comprising for causing a computer to execute:
- generating a walking waveform by using sensor data regarding motion of a foot acquired by a sensor installed in footwear;
- detecting a timing at which a clearance of a toe is minimized from the walking waveform;
- and
- calculating a minimum value of the clearance of the toe by using a walking parameter at the timing at which the clearance of the toe is minimized.
A program recording medium recording a program causing a computer to execute:
