Talk:OLPC Human Interface Guidelines/The Sugar Interface/Text and Fonts

Has anybody done any usability testing on screen/keyboard readability and layout?

If you're going to do this, you'll need a wide cross-section of potential users:

- Children of all ages and incomes
- Folks with vision/dexterity issues
- Older folks
- Color-blind
- Computer-literate
- Computer-illiterate
- Language illiterate

Also, there are going to be some cultural/language issues here. Having different keyboards available for different "country kits" is good.

Fonts

The choice of DejaVu LGS Sans as the default font is poor and shows that there has been no input from someone involved in teaching those learning to read and write. In particular the two storey letter a is one of the biggest problems facing those learning to read and write. On the plus side DejaVu LGS Sans does not compound this with a two storey g. The number 4 also fails, it should be like an upper case L with a line through it. I suggest looking at the SIL Andika font. If you take design review B, and change 7,a,g,t with those from design review A you have a suitable font for children learning to read with a Latin alphabet. --Jabuzzard 18:11, 19 June 2007 (EDT)
