Fanctionality and Cognition of Agent Icons in Virtual Space

考察了主体图标在三维虚拟空间中的功能与认知之间的关系。四个设计元素是具体性、功能性、维度和复杂性。在这些设计元素的设计概念下绘制了代理图标，并检查了这些图标的可理解性。此外，还进行了新的图标图像间心理距离的评价实验。这些实验的结果显示了与每个设计元素相对应的设计指南。此外，还设计了四个元素之间有联系的图标，并对它们的可理解性做了进一步的实验。在此基础上，重新提出了高认知图标的设计准则。其次，对三维智能体图标的操作进行了实验。受试者被要求戴上液晶快门红色眼镜。屏幕上显示的球状图标。受试者进行了三维…检查鼠标多用L的6个自由度来指向目标图标。结果表明，光标到图标的距离与操作时间呈正相关，图标的大小对操作时间有影响。这些发现也表现在二维空间中的点运算特征上。在图标靶标周围经常可见微小的点改变。然而，菲茨定律是关于3D鼠标的总操作得出的。再次，研究了虚拟空间中图标位置的估计方法。A是从光标位置到目标图标的距离，A被定义为从光标位置到目标位置的矢量的角度。根据这些参数定义了评价函数。改变了这些参数的系数，并进行了实验。该方法在操作时间和正确命中率方面均优于序数法。然而，它不能说明角度和距离中的哪个参数对估计有很大的贡献。下一步的工作是研究以学科运作模型为中心的估算方法。较少

Relation between function and cognition of agent icons in three-dimensional virtual space was examined. Four design elements were concreatness, functionality, dimensionality and complicatedness. Agent icons were drawn under the design concepts about these design elements, and comprehensibility of these icons were examined. Moreover the evaluation experiment by the new measure of the mental distance between the icon pictures was carried out. Results from these experients a design guideline corresponding to each design element were shown. Furthermore, the icon that have relations among the four elements was designed, and an experiment was further done about their comprehensibility. Then, the design guideline of the high cognitive icons was proposed newly. Secondly, the experiment about the operation of the three-dimensional agent icons was done. Subjects were made to attach liquid crystal shutter red glasses. The globular icon presented on the screen. Subjects operated a three-dimensiona … More l mouse with a degree of 6 freedom to point target icons. Results showed that the distance from cursor to the icon and operating time had positive relationship, and the size of icons effected to the operating time. These findings were also shown in a point operation character in the two-dimensional space. Minute point modification was seen frequently around the icon targets. However, the Fitts' law was concluded on the total operation of the 3D mouse. Thirdly, The estimation method of an icon position in the virtual space was examined. A distanced was from the cursor position to the target icons, and an agle a was defined as angle of the vector from a cursor position to a target position. An evaluation function by these parameter was defined. The coefficient of those parameters was changed, and an experiment was carried out. Proposed estimation method was superior to the ordinal method in operating time and correct hitting rate. However, it couldn't show which parameter of the angle and the distance contributed to the estimation strongly. Future work is to examine the estimation method centered in the operation model of the subject. Less
