Mr Shane, my idea was just a wild thought. However, if we can put in few sensors may be in our chairs to check if the user is sitting in a right posture. This sensor can be of ultrasonic sensor that measures the distance of the body. Collecting these information through an application we can identify the posture. Once the posture is identified an alert is to given to the user. As nobody wants their health to be affected, the users will make themselves comfortable and continue the works. I need supports from engineers and professionals to make these ideas implementable. I am just an idea generator.
