由于大多数计算机化信息是视觉信息，盲人和视力受损者无法直接获取。在讨论图形虚拟环境时，这一挑战尤为巨大。这尤其不幸，因为此类环境对盲人社区在社交互动、在线教育，特别是在自家安全舒适的环境中进行安全移动训练等方面具有巨大潜力。虽然先前的一些尝试提高了这些环境的可访问性，但当前的工具仍远不能使其完全可访问。我们建议使用感官替代设备（SSDs）作为提高此类环境可访问性的又一步骤，通过其他感官为用户提供更多关于场景的原始“视觉”信息。具体而言，我们在此探讨基于EyeCane的一种最简感官替代设备的使用，它使用单个像素的点深度距离信息，用于虚拟形状识别和虚拟导航等任务。我们展示了用户在这些任务中使用这种转换的成功案例以及快速学习的情况，证明了这种方法的潜力，并最后呼吁将其添加到可访问性工具包中。
As most computerized information is visual, it is not directly accessible to the blind and visually impaired. This challenge is especially great when discussing graphical virtual environments. This is especially unfortunate as such environments hold great potential for the blind community for uses such as social interaction, online education and especially for safe mobility training from the safety and comfort of their home. While several previous attempts have increased the accessibility of these environments current tools are still far from making them properly accessible.We suggest the use of Sensory Substitution Devices (SSDs) as another step in increasing the accessibility of such environments by offering the user more raw "visual" information about the scene via other senses. Specifically, we explore here the use of a minimal-SSD based upon the EyeCane, which uses point depth distance information of a single pixel, for tasks such as virtual shape recognition and virtual navigation. We show both success and the fast learned use of this transformation by our users in these tasks, demonstrating the potential for this approach and end with a call for its addition to accessibility toolboxes.
