Testbed evaluation

From EuroVR Knowledge Base


Description

Testbed evaluation has been carried out with VEs (e.g. Bowman, Johnson and Hodges, 2001; Bowman, Gabbard and Hix, 2002). This approach involves examining the effect of a primary independent variable (e.g. a particular interaction device or technique) as well as varying as many other potential factors which could have an impact on the experimental results (e.g. system (e.g. frame rate), task (e.g. size of object to be manipulated), environment characteristics (e.g. number of obstacles, level of motion in the VE), user characteristics (e.g. spatial ability, hand span)). Evaluation of interaction is often conducted outside the context of specific applications and usually involves large numbers of participants (see Bowman and Hodges, 1999). Testbed evaluation is conducted when quantitative, statistical results are desired.
