Description & Goals

Summary

This is a very simple Activity which provides non-interactive screen images of a ruler, cm and mm grids, and a cm checker board.

The checker broard is mainly intended as a photo target, though moving your head in and out shows interesting perception distortions.

Goals

• In TRIAL-2, determine how badly the screen gets dinged up when used as a ruler.
• Provide an accessible tool to measure screen-sized objects.
• Encourage length/area measurement, counting.

Collaboration

None direct. Intended as a supporting tool for exploring the world.

Development

It is not clear how/whether useful these will be, but it seemed worth trying.

I attempted to have a low knowledge barrier to use, while still having some thought provoking subtleties. But as a corollary to "if it wasn't tested, it doesn't work", this hasn't yet been user tested, so... . I would appreciate feedback from folks with xo's. I will try before TRIAL-2 deadline to print some mockups and test those.

There are lots of variations which could be tried. But, available developer time is limited.

Status

TRIAL-2 feature complete. Needs l10n, and testing on real hardware.

History

• 2007-08-08 Renamed activity to Ruler.
• 2007-07-13 Rule-1.xo Considered renaming project to Ruler from Rule. Haven't yet. People don't like the current name. And as this is more of a tool than an "activity", we could stop bending over backwards to follow HIG naming guidelines that a verb be used. This might also simplify translation. Though "rule" is more applicable to the grids than "ruler" is. Blech.
