Multimodal Interactive Line-Drawing Presentation Used for Visually Alternative Interface

提出了一种针对盲人心理地图创建支持系统的听觉感知辅助系统：在实验中处理城镇地图，并将传递情况的语言信息用作声音的方式。研究结果表明：□测量地图型心像图生成（使用4声道环绕立体声，类似于）显著上级其他方法，□对包含4或5条道路和10个物体的心像图，平均耗时289 s，正确回答率达到73%。该系统的机械部分由一个2自由度四边形并联杆驱动器和一个嵌入在并联杆臂端的转动驱动器组成。二自由度机械臂由两个伺服电机控制臂端位置。臂端致动器控制附接到旋转致动器轴线的旋钮的方向。假设人用他/她的指尖捏旋钮。旋转旋钮以指示正在进行的笔划的方向，旋钮轴的位置按顺序跟踪所呈现的图形的笔划。□在这个过程中嵌入了两个突出的功能：一个是通过“方向指示功能”的准备效果，另一个是通过“牵引功能”的回顾效果。“方向指示和牵引功能起着互补的作用。□作为呈现封闭五边形的心理物理实验的结果，我们证实了指尖引导操纵器上级凸起书写器，即，从使用中的精神压力的观点来看，通常使用的工具，然而对于指尖引导操纵器和凸起书写器，感知所需的消耗时间都是大约30秒。

An auditory sensation-aided system aiming at a mental-map creation support system for blind persons were proposed : town maps are treated in the experiments, and verbal messages that transmit situations were employed as a manner of sound. The results were as follows□The so-called survey map type mental map creation (using 4ch surrounding stereo sound, similar to the) was significantly superior to the others.□For the maps containing 4 or 5 roads and 10 objects, it took the time of289 seconds at average, and it achieved 73 % of correct answer rate.Next, a fingertip leading manipulator to support mental image creation was developed. The mechanical part of the system is composed of a 2-DOF quadrilateral parallel-link actuator and a rotational actuator embedded at arm-end of the parallel-link. A couple of servomotors of the 2-DOF manipulator control the arm-end position. The arm-end actuator controls the direction of a knob attached to the rotational actuator axis. The person is assumed to pinch the knob by his/her fingertips. The knob is rotated to indicate the direction of the on-going stroke, and the position of the knob axis traces the strokes of the presented figures sequentially.□A couple of preeminent functions are embedded in the process : one is a preparation effect by "the direction-indicating function," and the other is the reviewal effect by "the traction function." The direction-indicating and traction functions play complementary role.□As a result of the psychophysical experiments where closed pentagons were presented, we confirmed that the fingertip leading manipulator was superior to the raise writer, i.e., the generally used tool, from the viewpoint of mental stress in use, yet the consumption times needed for perception were approximately 30 seconds for both the fingertip leading manipulator and the raise writer.
