“…Both students started with a more conjoint reading strategy and ended with a more disjoint one. According to Breidegard and his colleagues (2006), this pattern suggests that they started with efficient and profound reading skills. These basic strategies helped them to read and solve the expressions.…”

“…In disjoint reading, the two index fingers explore different parts of the line. According to Breidegard, Jö nsson, Fellenius, and Strömqvist (2006), conjoint reading is most appropriate for efficient and deep reading and disjoint reading for global scanning of text. Perea, Jiménez, Martín-Suesta, and Gó mez (2015) used the term linger when the reading finger is slowing down and lingering on one braille cell.…”

“…The tactile reading strategies of braille readers can be studied through finger-tracking technology (Breidegard, 2007; Breidegard, Jönsson, Fellenius, & Strömqvist, 2006; Breidegard et al, 2008; Hughes, McClelland, & Henare, 2014; Perea, Jiménez, Martín-Suesta, & Gómez, 2015). The tactile perceptual window, approximately equal to one finger pad, is much smaller than the visual perceptual window (Loomis, Klatzky, & Lederman, 1991).…”

Introduction: Braille readers encounter difficulties when reading mathematical expressions. In this exploratory study, we created a setting to investigate these difficulties. Method: Using a motion-capturing system, we analyzed the tactile strategies of three braille readers while they read mathematical expressions. To compare tactile with visual reading strategies, we also analyzed the oculomotor performance in five print readers. Results: The analysis showed that the two experienced braille readers needed about 3.5 times as much time as print readers to read and solve four items involving mathematical expressions. The braille readers used personal reading strategies for all items with little use of the structure of the expression. In contrast, the reading strategies of print readers showed item-dependent and structure-related characteristics. Discussion: The braille readers had difficulties, within the constraints of tactile reading, to align their reading strategies with the solution procedures required by the mathematical structure of the items. Implications for practitioners: Teachers need to become aware of the kind of problems that braille readers confront when they try to comprehend and solve mathematical problems.

“…This movement is referred to as lingering on a braille cell (Perea et al, 2015). Conjoint reading is most suitable for efficient and deep reading and disjoint reading for global scanning of text (Breidegard et al, 2006). Our assumption is that braille readers can be supported in comprehending the expression’s mathematical structure and in the calculation or solving process by using specific finger movement strategies.…”

Braille readers read and comprehend mathematical expressions while moving their fingertips over braille characters. The aim of this exploratory study was to investigate the effect of an intervention that teaches braille readers who use a braille display to use finger movements with a focus on the expression’s mathematical structure. The finger movements involved movements where the two index fingers are about one or two braille cells apart and movements where the index fingers explore different parts of the expression. We investigated to what extent the intervention supports an interplay between finger movements and the expression’s mathematical structure to make the process of calculating the value of an expression easier and to make braille readers more aware of the expression’s structure. Three braille readers, respectively in Grades 7, 8, and 11, received the intervention consisting of five individual lessons. During the pre-, post-, and retention test, the braille readers’ finger movements were video recorded, as well as the time needed to read and process the mathematical tasks. Four expressions were selected for further analysis. The results show that during the posttest, each braille reader required at least 29% less time to read and process the expressions. The retention test results were even better. Scanpaths indicated that braille readers picked up features of mathematical structures more easily after the intervention. Based on our findings, we recommend that braille readers receive lessons in tactile reading strategies that support the reading and processing of mathematical expressions and equations.

“…A microphone registered the conversa tions and oral reading during the test sessions. The results of the pilot study (for which the technology described here was developed), along with its interdisciplinary backgrounds and procedures have been published (Breidegard et al, in press;Breidegard, Fellenius, Jönsson, & Strömqvist, 2006). This article deals mainly with the technical aspects.…”
