| 中文摘要 | Touch is an important sense of human beings. Line drawings are extremely useful to blind people, but identifying them by touch is far from easy. Past research demonstrates that many factors influence the tactile drawings recognition. However, line drawings of three-dimensional objects design for blind people based on knowledge about visual (rather than haptic) perception, the monocular cues of line drawings (such as perspective, superposition, hollow-out and texture) may interfere with the tactile recognition. Perspective, one of the picture features, is the most common visual monocular cue. Drawing a 3D object involves perspective and perspective features related to the object viewpoint. Visual system through perceptual learning can quickly and effectively process perspective, formed an object imagery system (involving the size, shape and texture of objects) and spatial imagery system (involving the space relation, perspective and viewpoint of objects)，and accurately identify 3D information expressed by the two-dimensional(2D) images. However, there are a few works attempting to detect whether the haptic system can recognize two-dimensional images as efficiently as the visual system and related factors, whether the tactile system is affected by object imagery system and spatial imagery system. What role does monocular cue play in haptic recognition of 2D images? In this research, two studies were conducted to investigate the factors underlying tactile recognition of 2D images and their cognitive mechanisms. Study 1 use the drawings of common objects , to investigate the factors that influence 2D images of tactile recognition. The perceptual factors included line complexity, four visual monocular cues (perspective, hollow-out, superposition and texture). Semantic factors included shape diagnosticity, image agreement and semantic categories. Individual difference factors included manipulation experience and visual experience. The results showed that perspective was negatively correlated with blindfolded people's overall haptic recognition performance in the four visual monocular cues. However, perspective could improve the haptic recognition performance of blindfolded people in the 2D animal images. Different from the sighted people, the blind people's recognition performance was significantly negatively correlated with perspective, texture and hollow-out, and regression analysis showed that perspective would impede the blind people's recognition. Shape diagnosticity and image agreement have significant predictive effects on the visual haptic recognition of 2D images. Due to the lack of visual experience, it is difficult for the blind to rate the image consistency. Based on Study 1, Study 2 attempted to use geometric objects unrelated to the individual's life experience and knowledge and tightly controlled haptic recognition experiments to investigate the 4 visual monocular cues(perspective, hollow-out, superposition and texture) and the role of object imagery ability and spatial imagery ability between 2D images and 3D objects in haptic recognition. The results show that p perspective, hollow-out, superposition and texture can hamper the haptic recognition of 2D images, but such negative effects are only found in 2D images matching 2D images, indicating that visual factors can affect the haptic recognition of 2D images, and object imagery ability and spatial imagery ability do not affect the haptic recognition of 2D images. Based on previous studies, this study attempts to propose a "dual image processing model" to explain the cognitive mechanism of 2D to 3D spatial information conversion when touching 2D images. The model suggests that haptic recognition of 2D images depends on the integration of two imagery systems, object imagery system and spatial imagery system. Finally, the information of the two imagery systems is integrated, and the mapping between 2D images and 3D space is established on the basis of the successful matching of object imagery and space imagery, and the 3D object representation in the long-term memory is accessible. The present study aims to reveal the cognitive mechanism of haptic recognition of two-dimensional images by examining the influencing factors of haptic recognition of images and whether the haptic system can effectively recognize 2D images through perceptual learning. This study can not only help to understand the mechanism of haptic perception, but also provide theoretical guidance for the blind people to human-computer interaction and terminal in the application field. |
| 英文摘要 | 触觉是人类重要的感觉通道之一。触觉识别二维图像对于盲人获取平面图像信息尤其重要，但是触觉识别二维图像却非常困难。目前，在将三维物体转换为平面二维可触摸的图像时，所基于转换原则仍然是基于视觉呈现的原理，二维图像所表现出的视觉单眼线索（如透视、遮挡、镂空和细节纹理）可能会干扰对这种二维图像的触觉识别。其中，透视是二维图像中最常见的视觉单眼线索特征，若是将同一物体旋转不同角度，在平面上画出两幅角度不同的二维图像，势必会涉及透视信息的变化。经过大量的知觉学习，我们的视觉系统可以快速、高效地加工透视等视觉单眼线索，形成物体表象系统(涉及物体的大小、形状和纹理)与空间表象系统(涉及物体的空间关系、透视和视角)，准确地识别二维图像所表达的三维立体信息，但是触知觉系统是否可以准确地加工二维图像所表达的三维立体信息，触觉系统在识别二维图像时是否会受到物体表象系统和空间表象系统的影响，以及视觉单眼线索在触觉识别二维图像中发挥什么样的作用，目前仍未有系统的研究。本研究围绕上述问题，采用两个研究考察视觉单眼线索以及物体表象和空间表象在触觉识别二维图像中的作用及其认知机制。 研究一拟采用日常物体的线条图，全面系统地考察影响触觉识别二维图像的因素，其中知觉因素包括四个视觉单眼线索特征（透视、镂空、遮挡和细节纹理）和线条复杂度，语义因素包括形状诊断性、形象一致性和语义类别，个体差异因素包括操作经验、视觉经验。结果发现，对于蒙眼明眼人，四个视觉单眼线索中，只有透视与总体的触觉识别绩效呈显著负相关，但是在动物类别的二维图像中，透视可以促进蒙眼明眼人的触觉识别绩效；与明眼人不同，盲人的识别绩效与透视、纹理、遮挡都呈显著负相关，回归分析显示透视会阻碍盲人的识别。形状诊断性和形象一致性对明眼人触觉识别二维图像有显著的预测作用，盲人由于缺乏视觉经验，较难对图像的形象一致性进行评估。研究二在研究一的基础上，试图通过采用与个体生活经验和知识无关的几何物体，以及严格控制的触觉识别行为实验，进一步考察 4 个视觉单眼线索（透视、遮挡、镂空和细节纹理）以及物体表象能力和空间表象能力在触觉识别二维图像中的作用。研究结果发现二维图像的透视、细节纹理和遮挡会阻碍二维图像的触觉识别，但是这类负面影响仅在二维图像-二维图像中发现，表明视觉因素会影响触觉识别二维图像，物体表象能力和空间表象能力并不会影响触觉识别二维图像。 结合已有研究, 本研究试图提出“双表象加工模型”来解释触摸二维图像时二维到三维空间信息转换的认知机制。该模型认为触觉识别二维图像依赖于物体表象和空间表象两个表象系统的整合。两种表象系统的信息最终进行整合,在物体表象和空间表象成功匹配的基础上建立二维图像与三维空间之间的映射,通达长时记忆中的三维物体表征。 本研究通过考察视觉单眼线索在触觉识别二维图像中的作用及其认知机制，试图揭示触觉识别二维图像的认知机制，加深对触知觉机制的进一步认识，也有助于在应用领域为盲人触觉图像交互界面和终端的二维图像设计提供理论指导。 |
