Dear Dr jadav it is nice to see your interest in one of the neglected section of industrial population, It is worth to take up. you will have to carry out through antheropometric measurement of user. then take operational measurement of controls. find out 5th & 95th percentile value of your antheropometric data of user&control, find out the most acceptable one . based on this make prototype go for trials, best trial values will be you dimensions of user&control. Improve over a period of time for perfection. I hope I am clear to you. do it go ahead. PCG,CLI
