Supporting novice waiters by indicating next action based on partial task integration algorithm

Staffs are classified to veterans and novices. When executing a certain amount of tasks, novices need time more than veterans because novices cannot decide which task should be done next and take long time to execute each task. In this paper, we focus on the problem that novices who are requested many tasks cannot judge which task should be executed now, and propose a system which constructs the appropriate order of tasks and present the proper action to novices to solve the problem. In the system, we introduce “Partial Task Integration” algorithm that can shorten the time for executing tasks by integrating some actions in different tasks to one action. To evaluate this system, we have implemented two types of the prototype, and experimentally compared task execution time and mental burden on prototypeusing case and no-system case. As the result, prototype-using case took longer time than no-system case because the time for looking at the display to confirm the next action are needed.
