在这项研究中，我们研究了GUESS系统在盲人和视障人士的听觉模式感知探索中的应用。我们比较了通过非语音声音呈现图形场景的三种不同技术：一种基于物理平板电脑，一种基于虚拟声音网格，还有一种基于声音定位技术。在每种技术中，我们都使用2D声音平面来表示不同的几何形状。作为输入设备，我们使用图形平板来探索呈现的图像。我们进行了一项试点研究，分为三组，每组四人。我们的研究结果表明，使用第二种和第三种技术，盲人能够在相对较短的时间内，精确地识别简单几何形状的相互关系。他们还表明，在第二种技术中，将非语音分配到位于平板电脑中心的区域，在重新定位特定形状时减少了导航时间。至于第一种技术，它在重新定位物体时获得的时间评级最低。我们的研究结果表明，在听觉界面设计中，呈现相互关系的方法确实在帮助用户理解所传达的图表方面发挥了重要作用。
In this research we investigated the use of the GUESS system in the exploration of auditory pattern perception by blind and visually impaired people. We have compared three different techniques for presenting graphical scenes via non-speech sounds: one based on the physical tablet, one on the virtual-sonic grid, and one on sound localization techniques. In each technique we utilized a 2D sound plane to represent different geometric shapes. As an input device, we used a graphical tablet in order to explore the images rendered. We have conducted a pilot study with three groups of four participants each. Our results have shown that with the second and third techniques, blind people were able, within a relatively short space of time, to precisely identify the interrelation of simple geometric shapes. They have also shown that, in the second technique, assigning a non-speech sound to a region located in the center of the tablet reduced the navigation time when relocating specific shapes. As to the first technique, it received the lowest time rating for relocating objects. Our findings indicate that the method of presenting interrelation in auditory interface designs does indeed play an important role in assisting users comprehend the diagrams communicated.
