28. Does meeting through standard video conferencing affect trust formation when compared to face-to-face? Can we improve trust formation patterns by using a spatially faithful video conferencing system such as MultiView?

29. Experimental Conditions Face to Face MultiView Standard Video Conferencing

31. Results: Overview

32. Results: Overall Trust Face-to-Face vs. non-Directional Video Conferencing, p<0.05 Directional Video Conferencing vs. Non-Directional Video Conferencing, p<0.05 Face-to-Face vs. Directional Video Conferencing, p>0.05 2600.09 2627.64 1928.28

33. Results: Overall Trust Face-to-Face vs. non-Directional Video Conferencing, p<0.05 Directional Video Conferencing vs. Non-Directional Video Conferencing, p<0.05 Face-to-Face vs. Directional Video Conferencing, p>0.05 4.424 4.388 3.562

34. Results: Overview

35. Results: Fragile Trust Face-to-Face vs. non-Directional Video Conferencing, p<0.05 Directional Video Conferencing vs. Non-Directional Video Conferencing, p<0.05 Face-to-Face vs. Directional Video Conferencing, p>0.05 -1.968 -2.348 -4.520

36. Ability to Build Trust… … not always good!

37. Conclusions Does meeting through standard video conferencing affect trust formation when compared to face-to-face? YES! Can we improve trust formation patterns by using a spatially faithful video conferencing system such as MultiView? YES!
