[chisigmail] FW: auto-suggest

[Tania]

Hi Ben
I don't know of any articles but I can pass on general results of usability
testing we have conducted with general public demographic when testing forms
with auto-suggest e.g. for address or suburb.

My only note would be to be sure you accommodate what we call "hunt and
peck" typists. We notice quite a number of people look down at the keyboard
whilst typing and only look up after they have finished. When activation
occurs after the first 3 characters happens, these users often don't notice
this.  That is not to say you shouldn't include these types of accelerators
for more advanced users but just be aware of it.

I imagine that it will depend a lot on the specific system you are building
and the likely technical savviness of your users.

Cheers

Subject: [chisigmail] auto-suggest

Hi all,

I am currently working on a proposed implementation of an auto-suggest
feature on a web form (in particular, a search).

I'm wondering if there are any articles out there that have analysed various
implementation of such a feature and ranked them based on their 
effectiveness - particularly with regard to what are the dos and don'ts for
using this sort of feature.

As an example, using a limited set of high level suggestions, versus a more
complete set ranked by popularity; activation on focus to the field vs 
activation after the first 3 characters have been keyed, etc.

Any recommendations would be appreciated.

Regards

Ben
