| Summary: | 碩士 === 國立成功大學 === 工業設計學系碩博士班 === 94 === In order to prevent losing of efficiency and accidents caused by misemploying the hand controls, this study investigates responses from 20 experimenters with 35 different sizes of hand controls and focused on the relationship between size cognition and behavior. Gibaon suggested that a kind of ratio between object and human will act on our behaviors to the hand controls. Also, the previous research of Warren and Anii tell us that there should be a variate of ratio associated with the percentage of human behavior. Accordingly, this study supposed a variate and tried to prove it by regression analysis. The conclusions of this study are described below.
1.A variate of ratio (Vr) associated with the percentage of human behavior is:10**4(D/H)/LW
2.The percentage of behavior of “Turn” can be estimated by formula:
Yt=0.503＋0.102Xvr－0.112Xvr**2＋0.015Xvr**3
with (Vr) . (R Square = 0.970 , p <0.05)
3.The percentage of behavior of “Press” can be estimated by formula:
Yp=0.409Xvr－0.051Xvr**2＋0.001Xvr**30-0.117
with (Vr) . (R Square = 0.992 , p <0.05)
4.The Vr point 1.65 and 6.65 mean the percentage of behavior of “Turn” is equal to the percentage of behavior of “Press”.
5.The Vr point 0.6 and between 4~5 mean the percentage of behavior of “Turn” and “Press” reaches the maximum.
