We constructed a system which enables a student to attend classes using an alter ego robot which provides scenery of the class to the student through a monitor in front of the student. It is important to restrict the amount of information on the class lesson given to the student to avoid decrease in concentration. As a method to restrict the amount of the information, we propose a service in which notable description on the blackboard pointed by the teacher is magnified and shown to the student through the monitor. The parameters which can affect human psychology such as magnification rate, tracking characteristics to the change of the pointed position, the timing to return from magnification to the normal display when the pointing motion ends, are evaluated by the Semantic Differential method. It is clarified from the factor analysis that the emotion to the service can be expressed by the factors of legibility, emotionality and stability. In addition, the desirable magnification rate, breakpoint frequency of the first order delay characteristics to the change of pointed position, and dead time before returning to the normal display are clarified.

In comparison with the conventional methods based on either confocal microscopy or optical coherent tomography, the proposed method can achieve both surface profile measurement and wider measurement area of car body panels. In this method, the reconstructed amplitude and the phase distribution of the object wave reflected from each paint layer can be obtained and used for investigating both the surface profile of the coating film and the distribution of bright materials in the desired paint layer. It is shown that the thickness of the clear paint layer on two pieces of gray car-body-panels having the different appearance is different and the depth distribution of the bright materials shows a local variation in both body-panels. In addition, by comparing the results with optical microscope observation, it is suggested that the paint appearance depends on the thickness of the clear coat layer in the car-body-panel.","PeriodicalId":145372,"journal":{"name":"産業応用工学会論文誌","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127256809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By pushing with same one finger, a pushing force is acted to the developed drawing compasses in only one direction, and the circle is drawn. In this paper, a structure, a mechanism and form changes about the developed drawing compasses were shown. An analytical model was generated for analyzing the pushing force and the writing pressure.
