Reverse engineering (RE) is the process of defining and instantiating a model based on the measurements taken from an exemplar object. Traditional RE is costly, requiring extensive time from a domain expert using calipers and/or coordinate measurement machines to create new design drawings/CAD models. Increasingly RE is becoming more automated via the use of mechanized sensing devices and general purpose surface fitting software. This work demonstrates the ability to reverse-engineer parts by combining feature-based techniques with freeform surface fitting to produce more accurate and appropriate CAD models than previously possible.

Purpose The authors aim to examine the effect of location-driven logo placement on attention and memory on the web addressing differences between individuals that read unidirectionally (left-to-right [LTR]) versus bidirectionally (both right-to-left and LTR). Design/methodology/approach Using an eye-tracking approach combined with traditional verbal measures, the authors compared attention and memory measures from a sample composed of bidirectional (Arab/English) readers and unidirectional readers. Findings The findings reveal that unidirectional and bidirectional readers differ in attention patterns. Compared to bidirectional readers, unidirectional readers pay less attention to the logo on the bottom right corner of the webpage based on verbal measures. The eye-tracking data of the two groups further identify differences based on total hits and duration time. Unidirectional LTR readers demonstrate higher fluency in feature-based attention whereas bidirectional readers show higher fluency in spatial attention. Originality/value The authors expand on scarce research on reading direction bias effect on location-driven stimuli placement in online settings. They contribute to the understanding of the differences between unidirectional and bidirectional readers in their cognitive responses (attention and memory) to organization of marketing stimuli.
