USAB 2008, November 21 Beat Signer, [email protected] Setup ▪ Hardware ▪ laptop (n=8) and tablet PC (n=1) ▪ pointing device: laser pointer (n=7) or stick (n=1) ▪ remote control (n=6) ▪ Software ▪ PowerPoint 2007 (n=4), PowerPoint 2004 (n=1) and PowerPoint 2003 (n=4) ▪ All participants use PowerPoint since more than 7 years Results 

USAB 2008, November 21 Beat Signer, [email protected] Content and Organisation ▪ all participants sort the slides in the order they intend to present them ▪ most participants (n=8) access the slides in a linear order MIN_SLID MAX_SLID MEAN_SLID Trial 0 10 20 30 40 50 60 70 80 90 100 Measure min max mean number of slides Results 

USAB 2008, November 21 Beat Signer, [email protected] Content and Organisation … ▪ most participants (n=8) use extra slides ▪ filed at the end (n=6) ▪ filed as hidden slide (n=2) ▪ stored in separate file (n=2) TEXT FORM GRAPH Trial 0 10 20 30 40 50 60 70 80 90 100 Measure % text formulas graphics type of content Results 

USAB 2008, November 21 Beat Signer, [email protected] Presenting Information ▪ All participants like to move around during a presentation ▪ Most participants use additional types of media ▪ black-/whiteboard (n=9) ▪ overhead slides (n=7) ▪ videos (n=6) ▪ software/application demos (n=2) ▪ flipcharts (n=1) Results 

USAB 2008, November 21 Beat Signer, [email protected] Implications Description Highlight and annotate slide content Use blank "sheets" Use video controls Use system mobile Orientate efficiently within slide collection See content of current and nearby slides Feature F01 F02 F03 F04 F05 F06
