What is important is to support different entry techniques - including users who know what option is available and can enter free text, users who need to select from a simple list or sequence, and users who are searfching for something but need spelling suppor. An example of the first is looking for a category in a directory of businesses sorted by business type - I know that what I want is "plant hire" while another person might want to enter "machines" becaseu they aren't familiar with that part of the directory. Another person might enter "mashine", and need a spellchecker. (Google has some spellchecking suggestions, and lots of systems provide for free text entry and selection from a list). Anopther example area to look at is VOiceXML, which caters very well for different styles of input. For people who are used to interacting with systems on the telephone, think of systems where it is possible to skip through quickly, or to get information on available options (although all the systems I have heard in the US claim that the system changed againrecently so it is important to listne carefully).

(User should have choice). 3- Should not have a checkpoint that says "handle input errors". Too open. Too many types of errors and they are not even listed. Also it is not possible to recover from or correct many types. (most errors?). What does "Handle" mean? CONCLUSION A - current guideline is unworkable as worded. B - good advice but not a checkpoint. C- not worded right even for advice right now. RECOMMENDATION: 1- It be changed to advice 2 - Reword as three pieces of advice as follows: "Where possible Provide suggestions when input is invalid due to spelling or other causes " "Where possible allow user to chose between selecting from a list and providing direct input" "Where possible User errors should be reversable or the user should be given a warning."
