Abstract
Abstract A real time, instant replay time-motion analysis system of work measurement that utilizes computer assisted video techniques to simultaneously record and display an operator at work and the elapsed time for the performance of each elemental step in his work task. An observer provides an input signal each time a step is completed and a subsequent step initiated, thereby causing the display of elapsed time relating to the first step to freeze and a display indicating running time for the second step to be generated. Input relating to interruptions occurring during the work process are manually and audibly provided to the system by the observer. The time related data generated during the study is calculated in a microprocessor, and presented as graphical illustrations on the video monitor during replay of the recorded information.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
93 words
A method for communicating information relating to a study of the work method of an operator performing a task composed of one or more elemental steps, comprising the steps of: making a video recording of the operator performing the task; measuring the elapsed time for performing each elemental step; simultaneously making a video recording of the measured elapsed times; and instantly replaying the video recording on a video monitor with a plurality of displays of elapsed time relating to the individual elemental steps of the work task upon completion of the work task.
Claim 2
Independent Claim
93 words
A method for communicating information relating to a study of the work method of an operator performing a task composed of one or more elemental steps, comprising the steps of: making a video recording of the operator performing the task; measuring the elapsed time for performing each elemental step; simultaneously making a video recording of the measured elapsed times; and instantly replaying the video recording on a video monitor with a plurality of displays of elapsed time relating to the individual elemental steps of the work task upon completion of the work task.
Claim 3
Dependent Claim
26 words
The method of claim 1 further including the step of displaying the video recording and elapsed time on the video monitor during the video recording step.
Claim 4
Dependent Claim
32 words
The method of claim 1 further including the steps of evaluating the working pace of the operator during the recording step, recording the evaluations, and displaying the evaluated working pace during playback.
Claim 5
Dependent Claim
31 words
The method of claim 1 further including the steps of calculating predetermined data from the elapsed time measurements taken during recording, and providing graphical illustrations of the calculated data during playback.
Claim 6
Dependent Claim
31 words
The method of claim 1 further including the step of providing cueing signals at predetermined locations on the recording medium to enable the video recording to be selectively addressed during playback.
Claim 7
Independent Claim
151 words
A method for measuring the work habits of an operator performing a work task including sequentially performed elemental steps and subsequently communicating the results of the measurements to the operator, comprising the steps of: providing a video recording of the operator performing the task; simultaneously displaying the video information being recorded; providing a running time indication relating to the elemental step being recorded on the display; generating a signal indicative of the completion of one elemental work step and the initiation of a subsequent work step; stopping the running time indication on the display upon the generation of said signal to thereby indicate elapsed time for the performance of the recorded work step and generating a second running time indication on the display relating to the initiated subsequent work step; recording the running time displays simultaneously with the video recording; and replaying the recorded information upon completion of the work task.
Claim 8
Independent Claim
151 words
A method for measuring the work habits of an operator performing a work task including sequentially performed elemental steps and subsequently communicating the results of the measurements to the operator, comprising the steps of: providing a video recording of the operator performing the task; simultaneously displaying the video information being recorded; providing a running time indication relating to the elemental step being recorded on the display; generating a signal indicative of the completion of one elemental work step and the initiation of a subsequent work step; stopping the running time indication on the display upon the generation of said signal to thereby indicate elapsed time for the performance of the recorded work step and generating a second running time indication on the display relating to the initiated subsequent work step; recording the running time displays simultaneously with the video recording; and replaying the recorded information upon completion of the work task.
Claim 9
Dependent Claim
82 words
The method of claim 6 further including the steps of generating a signal upon the occurrence of an interruption; temporarily halting the running time indication relating to the elemental work step and generating a running time indication relating to the interruption; generating a second signal upon termination of the interruption; and stopping the running time indication relating to the interruption and resuming the running time indication relating to the performance of the elemental work step upon the generation of said second signal.
