视觉、词汇和眼动信息的整合是阅读的关键部分。奇普斯是一个理想的观察者模式，他将这些信息源完美地结合在一起，以最少的扫视次数阅读简单的文本。在该模型中，视觉跨度(一次注视中可以识别的字母数量)的概念起到了关键的统一作用。该模型的行为为重新审视有关人类阅读眼跳的文献提供了一个计算框架。该模型的新特性，如倒退的眼跳和最佳观看位置，暗示了对人类行为的新解释。由于奇普的“视网膜”可以有任何(一维)的高分辨率区域和暗点排列，该模型可以模拟常见的视觉障碍。令人惊讶的眼跳策略与暗点模式有关。例如，奇普斯有时会计划一次扫视，把一个决定性的字母放在一个盲点中。本文首次提出了暗点对阅读影响的定量模型。
The integration of visual, lexical, and oculomotor information is a critical part of reading. Mr. Chips is an ideal-observer model that combines these sources of information optimally to read simple texts in the minimum number of saccades. In the model, the concept of the visual span (the number of letters that can be identified in a single fixation) plays a key, unifying role. The behavior of the model provides a computational framework for reexamining the literature on human reading saccades. Emergent properties of the model, such as regressive saccades and an optimal-viewing position, suggest new interpretations of human behavior. Because Mr. Chip's ''retina'' can have any (one-dimensional) arrangement of high-resolution regions and scotomas, the model can simulate common visual disorders. Surprising saccade strategies are linked to the pattern of scotomas. For example, Mr. Chips sometimes plans a saccade that places a decisive letter in a scotoma. This article provides the first quantitative model of the effects of scotomas on reading.
