Rather than just present stimuli and collect responses, Eye Lines can record mouse movements and allows subjects to manipulate images in real time. This provides easy access to designs and procedures not available with any other software.
|
Visual perception: Use method of adjustment to measure perceived size, position, angle of orientation, or shape distortion. Eye Lines will measure the magnitude of any conceivable variation on the classic geometric illusions (Müller-Lyer, Zöllner, Ponzo, Delboeuf, etc.). NEW for version 3.0 is the ability to use other psychophysical methods (method of limits, method of constant stimuli, and adaptive staircase.) |
 |
|
Sensory-motor testing: Flexible versions of mirror drawing and pursuit tracking that allow the user to design any path, and specify a variety of hand-eye distortions (reverse and/or stretch the vertical and/or horizontal dimensions). |
 |
|
Drawing / handwriting: Record performances for playback, timing, or other analysis.The entire drawing (or selected portions) can be replayed in real time. Playback can be speeded up or slowed down, or the the researcher can step through it line by line (either forwards or backwards) while simultaneously viewing a spreadsheet containing the x,y coordinates and creation time for each. To determine how long any component took to draw, select its first and last lines, then ask for a time calculation. Drawings can be made with a mouse or graphics tablet pen. |

|
Hidden Target Maze Learning: (analogous to Morris Water Maze) NEW for version 3.0 Experimenters design a maze by specifying the number, size, and position of invisible targets. Subjects move the mouse cursor around the screen until they locate all targets. El draw reports elapsed time and can replay all or part of the performance at normal or altered speed. Experimenter can specify whether the targets must be found in a particular order and whether they become visible as they are found. |

For Teaching - Eye Lines includes experiments and demonstrations of visual illusions, mirror drawing, and rotary pursuit tracking. However, this is not just a set of prepackaged exercizes with limited flexibility. Students can use any of these examples as a starting point to design their own stimuli and experiments, or they can start from scratch.
Highest Rated - In 1992, Psychology Software News gave Eye Lines 1.0 its highest (four star) ratings for both content and usability. The latest version supports more paradigms and is faster, and much easier to use. Read PSN's review (at LTSN Psychology site, U. of York) or Search LTSN database for other psychology software.
Technical Support by e-mail or phone - Recently an Eye Lines user was having difficulty with a complex image adjustment. As EL files are stored in text format, it was easy to append the image to an Internet e-mail message. We were able to edit the file and send it right back. Technical Support
Macintosh or IBM PC or BOTH - Eye Lines is the first Psychology research software to run on both Mac and PC. Further, each version can use the other's files without requiring file translation (Mac version has some added features not supported by PC.) System requirements
