Chapter 15: Block vs Point Technique
When using row-column scanning, how should groups be highlighted?
Block technique trades speed for clarity; point technique reduces visual clutter but requires more visual precision. Try both with real users.
Block technique
- Entire row lights up
- Easy to see
- Best for beginners and low vision
Point technique
- Only row indicator highlights
- Less visual clutter
- Best for dense grids and experienced users
Best practice: start with block technique for beginners, then experiment with point technique.
