This paper presents a new multi-criteria decision-making (MCDM) method, namely the ratio product model (RPM). We first overview two popular aggregating models: weighted sum (WSM) and (WPM). Then, we argue that models suffer from some fundamental issues mainly due to ignoring nature of alternatives' scores with respect criteria importance weights criteria. Building on notion compositional data a...

Text entry has been a bottleneck of nontraditional computing devices. One of the promising methods is the virtual keyboard for touch screens. Correcting previous estimates on virtual keyboard efficiency in the literature, we estimated the potential performance of the existing QWERTY, FITALY, and OPTI designs of virtual keyboards to be in the neighborhood of 28, 36, and 38 words per minute (wpm)...

PURPOSE To develop 27 short sentence optotypes for the Portuguese version of the Radner Reading Charts. METHODS Thirty-four Portuguese sentences were constructed following the concept of the Radner Reading Charts to obtain highly comparable sentences in terms of lexical difficulty, syntactical complexity, word length, number of syllables, and position of words. A long text (106 words) at the ...

Previous research in English has suggested that reading rate predictions can be improved considerably by taking average word length into account. In this study, we investigated whether the same regularity holds for Dutch. The Dutch language is very similar to English, but words are on half a letter longer: 5.1 letters per (in non-fiction) instead of 4.6. We collected rates 62 participants 12 te...
