Applied Motion Study
A Collection Method to industrial Preparedness

88 APPLIED MOTION STUDY such as the folding of cloth, it was desirable to take chronocyclegraphs from several points si- multaneously, in some cases placing the camera in front of the operator, at the right side, at the left side, and also above. A study of these rec- ords led to the realisation that it would be a great advantage, if it were possible to study the motion from all angles. An advantage to the mo- tion study man in eliminating all useless, ineffi- cient and ill-directed motions and in his general education in motion study. An advantage, also, to the worker, who could thus see his motions as he never could while doing the work. A special advantage to the learner desiring to acquire the skill in the shortest amount of time, and with the least amount of effort possible. This need was even greater in the case of surgery, where it was found impossible, because of the necessity for operating conditions, to take the photographs required in the usual manner. While the telephoto lens was a great help in mak- ing it possible to take necessary records from the amphitheatre of the operating room, thus neither disturbing the operating conditions nor adding a new variable, through the presence of an observer,
