Occlusion Method

As a method for HMI assessment of IVIS the occlusion technique is applicable for both assessing the visual demands of driving and simulating the interruption caused by doing some other task while driving (...). The occlusion technique is defined as a “measurement method involving periodic/intermittent physical obscuration of the participant’s vision or the obscuration of visual information under investigation” (ISO/ TC22/ SC13/ N763R). The occlusion technique is based on the systematic control of the permitted time intervals for a subject to glance at an object or perform a task. (Johansson et al., 2005)
