Walking, jogging or running are the most common and easiest form of physical exercises to implement. Usually, users like to wear pedometer devices when exercising to detect the specific number of steps and thereby assess the amount of exercise. Common pedometers include fitness bands, fitness watches, or mobile phone apps. However, these devices require users to swing their arms regularly during exercise, otherwise the step counting data will be inaccurate. To address this issue, this paper proposes a new solution, namely the principle of detecting staggered legs using infrared intrusion sensors. Unlike previous solutions, this appoach only requires wearing the device on one side of the leg. The experimental results indicate that the proposed design scheme exhibits high accuracy in step counting and remains unaffected by arm swinging.
