The occlusion Technique Keystroke Level Model (KLM) The KLM is predictive method which is a simplified GOMS derivative (Card et al, 1983). KLM makes several simplifying assumptions of CMS-GOMS that make it a restricted version of GOMS. It eliminates the goals, methods and selection rules leaving only primitive operators. The operators of the KLM include pressing a key (K operator), pointing with a peripheral device (P operator), movement of a hand between input devices (H operator), mental preparation (M operator), pointer drag movements (D operator), and response time (R operator). The placement of the keystrokes and pointer operations are straight forward, but the placement of the mental operations is not. Mental operations are usually placed by some heuristic method. The time for each operator has been empirically determined. Task time predictions are made by determining the operators required to complete a task and summing their time values.
Extended KLM In order to simulate occlusion trial, it is assumed that the sequence is assessed considering the vision/no-vision intervals of 1.5 seconds (vision) and 2 seconds (no-vision) as experienced by drivers during occlusion condition. Also, a series of local assumptions were suggested as part of feasibility. Decisions are based on the three following assumptions suggested by Petit (2007). (1) During 1.5 seconds periods of vision, the operator sequence can progress without interruption. (2) Operators that begin in vision periods can continue into an occluded period unless specifically associated with vision. (3) Operators can only begin in an occluded period when vision is not required at any point in its duration.
The occlusion technique is designed for simulating the situation of interacting with an IVIS while glancing to and from the road scene while driving. Occlusion is defined as ‘‘the physical obscuration of vision for a fixed period of time’’ (ISO/TC22/ SC13 WG8, N322 cited in pettit 2006). There are two common methods for occluding the vision. One of them is for the participant to wear goggles with LCDs that rapidly switch on (transparent) or off (opaque) controlled by a compute. Another method is to mount a shutter on top of the task display (usually an LCD) or to blank the display using software. Participants of a test are assessed during performing tasks on IVIS while participants’ view is interrupted at set intervals by occlusion goggle. The occlusion technique is considered to be low-cost and easy implementation compared to other method for assessing driving distraction.
