研究了用听觉代替视觉的模式识别方法。在15个1小时的疗程中，9名蒙眼视力受试者接受了试错法识别2D图案的训练。除了全球评估外，还对每种模式的模式元素性质(垂直条、水平条……)、元素大小和元素空间排列的识别进行了独立评估。研究了实验参数(模式的复杂程度、模式的探索次数)对识别的影响。随着时间的推移，表现有所提高。通常情况下，模式元素的性质不如元素大小和空间排列被很好地识别。实验参数影响模式识别性能。结果被讨论与听觉和视觉知觉，以及在实施为未来的假体使用者的学习协议的观点。版权所有(C)2006 John Wiley&Sons，Ltd.
Pattern recognition with a prosthesis substituting vision by audition was investigated. During 15 1-hour sessions, nine blindfolded sighted subjects were trained to recognise 2D patterns by trial and error. In addition to a global assessment, recognition of pattern element nature (vertical bars, horizontal bars...), element size and element spatial arrangement were independently assessed for each pattern. Influence of experimental parameters (complexity level of patterns, exploration number of a pattern) on recognition was studied. Performances improved over sessions. As a rule, patterns element nature was less well recognised than element size and spatial arrangement. Experimental parameters influenced pattern recognition performance. Results are discussed in relation with auditory and visual perception as well as in the perspective to implement a learning protocol for future users of prosthesis.
