I plan to start awarding designs in user assistance that I feel are well-intentioned but wrong. The purpose is not to ridicule (OK, ridicule a little) but to show how best intentions are not enough to make a good user assistance experience. The following screen capture is from an non-disclosed calendar application. Note the tool tip/Alt tag.
The problem is that it describes the icon when it should have explained the icon. I have no idea why this icon is on that entry or what it means. The description that it is an icon of a person waving his hand does not help the sighted reader, nor does it work as an Alt tag for a blind reader. Neither knows what it means.
The writers knew that an icon needs an Alt tag and provided a very accurate one. Bless their hearts.
