Facilities and computer programs for workload research were equipped and two experiments on the workload were completed. Furthermore, a concept about integration of multiple parameters was discussed.Devices for physiological signal measurement, video monitor system and a computer for task presentation were functionally arranged and linked for efficient performance and reliable signal recording in workload experiments. A mental arithmetic task program in which difficulty level varies automatically according to subjects' response (correct or not correct) and a specific mirror tracing task program that induces pattern 2 type response were written. Also, a program set named SIMPLE (Subjective Indexes and Mental task Program for Laboratory Experiments) was composed to execute task programs according to a predetermined scenario and to combine with programs for mood and subjective workload evaluation. An experimental system (software) which makes it possible to unify baseline recording (rest), task presentation, mood evaluation and workload assessment, and to calculate task performances and subjective responses in almost real time was established. Signal analysis programs for each physiological measure were written. Especially, programs for spectral analysis of heart rate variability were composed as the HEART (Heart rate variability Evaluation by Auto Regressive model Technique) SYSTEM and its manual was made.An experiment to evaluate comfort indirectly was performed in which workload research technique was used to investigate comfortable environmental factors such as aromas. The results suggest that knowledge on mental task and psychophysiological responses growing in workload research seems useful for research on comfort. On the other hand, results on task specific physiological responses were similar to findings in earlier studies.

配备了用于工作负荷研究的设备和计算机程序，并完成了两个关于工作负荷的实验。提出了多参数集成的概念，并将生理信号测量装置、视频监控系统和任务呈现计算机功能性地安排和连接在一起，以保证负荷实验的高效性和可靠性。编写了难度水平根据受试者的反应（正确或不正确）自动变化的心算任务程序和诱导模式2类型反应的特定镜像追踪任务程序。此外，一个名为SIMPLE（主观指数和心理任务程序的实验室实验）的程序集组成，执行任务程序，根据预定的情况下，联合收割机与程序的情绪和主观的工作负荷评估。建立了一个实验系统（软件），它可以统一基线记录（休息），任务呈现，情绪评价和工作负荷评估，并计算任务性能和主观反应几乎真实的时间。为每个生理测量编写信号分析程序。特别是编制了心率变异性的频谱分析程序HEART（Heart rate variability Evaluation by Auto Regressive model Technique）SYSTEM及其使用手册，并进行了间接评价舒适性的实验，实验中采用工作负荷研究技术对气味等舒适性环境因素进行了研究。结果表明，在心理任务和心理生理反应的研究工作量增长的知识似乎是有用的舒适性的研究。另一方面，任务特异性生理反应的结果与早期研究的结果相似。
