The product we use inside of our framework will probably come out with a LIVE GRID implementation. Here is a demo that someone has put together http://www.siteartwork.de/livegrid_demo/ His Blog may give your dev team some ideas on his implementation (although the technology may be different from yours) http://www.siteartwork.de/2007/11/10/livegrid-component-with-extjs/ I have not come across any formal design guidelines for live grid. However, I do think that the scrollbar jumping back is a major issue. As far as informing the user about what the range is they are viewing, I am wondering if it is necessary in all cases. If you display a "Total records: #####" at the bottom on initial display of the grid, do you need to constantly tell the user what specific range they are looking at? I remember reading that it is expensive to calculate with every scrollbar movement. In many cases, those numbers (range) may not mean much to user other than just providing a mere comfort feeling. -aras -----Original Message----- From: ACM SIGCHI WWW Human Factors (Open Discussion) [mailto:[email protected]] On Behalf Of Cindy Lu Sent: Wednesday, February 27, 2008 10:30 PM To: [email protected] Subject: Live Scroll - Usability Testing Feedback and Design Guidelines Hi! We have incorporated live scrolling function (or infinite scroll) into a beta product. We observed some issues from users such as the scroll bar jumps back when scrolling down, how to inform the user the range of visible records, etc. Have you used the live scroll feature in your product? Do you have any lessons learned that you can share? Do you know if there are any design guidelines for this function?
