For reading analysis, you need to define an Interest Area (IA) for each word. Data Viewer offers several ways to accomplish this.
Method 1: Automatic Creation with Experiment Builder
If you used Experiment Builder for stimulus presentation, the software can automatically generate precise, word-level Interest Areas for you. This is the most reliable and efficient method.
Method 2: Auto-Segmentation in Data Viewer
If you used other presentation software, you can use Data Viewer's built-in auto-segmentation tool.
Method 3: Manual Adjustments (Splitting & Merging)
If an automatic method produces errors (e.g., an IA containing multiple words), you can manually correct them.

- To use it: Click the Auto Segment Image into Interest Areas button on the toolbar.
- Function: This feature analyzes the stimulus image and creates IAs based on visual cues, such as the whitespace between words.
Method 3: Manual Adjustments (Splitting & Merging)
If an automatic method produces errors (e.g., an IA containing multiple words), you can manually correct them.
- To Merge: Select multiple Interest Areas, right-click, and choose Merge.
- To Split: Select a single Interest Area, right-click, and choose Split.
