It is most suitable for those who regularly exercise and want to improve further as it gives the count of distance coved and calories burnt during the work out. It comes with a chest strap which helps to monitor the individual’s heartbeat rate. It can be worn as normal watch as well, as it displays, date and time as well.
Some of its salient features like the technology behind it, how it was first discovered, how accurate they are and what is their usage and who can use it, are discussed below.
Discovery and Technology of Pedometer:
The pedometer is a portable device which can be carried away anywhere one may like to. It is an electromechanical device. The device detects the peculiar hip movement and counts the number of steps taken by an individual as the width of each step taken by every person is different and it determines what the speed of the person was.
Till date there is no such pedometer made, which is completely based on electronics or software which can determine the variations in steps. Thomas Jefferson was the first man who introduced this device to Americans as a mechanical device but later with the development in the technology it was designed within a watch mechanism with a digital display for more accurate readings and is hence, known as a pedometer watch.
The device includes software to monitor and record the number of steps and a mechanical sensor to detect the hip movements. Unlike early pedometers which had a mechanical switching system which detected the motion and counted them using a counter; today advanced sophisticated software is combined with MEMS sensors which have improved its accuracy and reliability to a great extent. The pedometer watch has all the features of a sports watch like an interval timer, backlight and a normal watch like alarm, date and time as well.
Accuracy, usage and pedometer application in other devices:
It can be disappointing for many that the accuracy of pedometers depends and varies largely from device to device. But there is a sigh of relief for users that if the device is correctly and appropriately used then it can produce reasonably accurate and exact results. It is advisable to use the device, while users walk and count the steps on flat surfaces where the device should be in the vertical position to the belt clip or where it has been attached.
Though with the recent advancements, which have made it more robust and tried to increase its accuracy but it still varies and does not give accurate results at different inclinations, angles and locations. While driving and other habitual movements the device is unable to detect exactly and produces false results. Even the best pedometers come with a nominal error of ± 5%.
The health department has proposed the step count of 10,000 steps per day so as to burn the extra calories and stay fit. But this target is very high for old people who have joint problems and extremely low for children. These days many mobile phones, i-pods and Mp3 players comes with the pedometer watch application to monitor the time elapsed and calories burnt.
