We have been using Movalzyer for over two years and have found it invaluable for our research needs. It is an easy to use program and the data can be exported for use with may other analysis or statistical programs. Any time we have a question or problem we have found the technical support has been very punctual and helpful. Thus far, we have been very pleased with the overall functioning of the program. We look forward to further developments to the software -- Avni Pepe, La Trobe University, Melbourne, Australia http://forums.graphonomics.org/showthread.php?t=133 & Jodi Sita, PhD, La Trobe University, Melbourne, Australia http://www.latrobe.edu.au/health/abo...le?uname=JSita

EYE MOVEMENTS DURING WORD WRITING

There is little evidence concerning the relationship between the eye and pen
movements for the production of a word. The present study examined gaze behavior
made during the writing production of single words for two writing tasks. For both
tasks the words all contained the element “log”, which contains examples of loops,
ascenders and descenders. The first task examined the effect of word size, in which 20
subjects wrote a set of 4 different words, each in three sizes (small, normal and large),
three times. The second task investigated the effect of the position of the element „log‟
placed at the beginning, middle and at end of a word. A Tobii x120 infrared eye
tracker running at 120 Hz was used with Tobii Studio 2.2.4 software to collect eye
movement data and a Wacom Intuos 3 digitizing pad with specialized inking pen was
used to capture pen movements. Writing dynamics were captured and analyzed using
Movalyser software version 5.4. We collected the number, duration and location of
each fixation, the writing velocity, the number of turning points made and the total line
length. We found that increased writing size resulted in more fixations but no
difference in the mean duration of these fixations. For letter placement within a word,
the number and location of fixations made on the element „log‟ tended to remain stable
regardless of its within word position, however fixations made on the element „log‟ in
the start position were significantly longer in duration than fixations made on „log‟ in
other positions. Finally, we observed that for many subjects, their gaze appeared to
move in a line parallel with the written trace, and did not appear to be drawn to any
salient ascending or descending features.
