The team at Zikto have developed a fitness tracker called Arki that is able to monitor your walking pattern to prevent poor posture. It measures all aspects of gait such as swing speed, stride length, limb rotation, and angle, and combines it with other data, to improve walking habit. If it detects that the wearer is slouching or doing something that leads to poor posture such as walking while viewing a phone, the device will vibrate.
Another very interesting potential application is biometrics. Walking patterns are as unique to a person as their finger prints or retina. Walking patterns could, therefore be used as a way to confirm a person's identity to enable the device to process payments, for example. It could also be used to replace passwords to access and control smart devices around the home.
The estimated delivery date is April 2015, and a "basic package" is available for $99 (£63). International shipping is available.
