JAMA Guideline for In-Vehicle Display Systems

The paper describes the main topics of the new guideline, which we call “3.0 version”. We executed the road tests to analyze driver's workload of various operations to the navigation system. As a result, the guideline regulated the upper limit of the Total Glance Time (TGT) 8 seconds. And we proposed a bench test which is called the Occlusion method using a LCD shutter goggle instead of road tests. In the occlusion method, 7.5 seconds of the Total Shutter Open Time (TSOT) corresponds to 8 seconds of the TGT. This is the first step of JAMA in achieving numerical criteria for in-Vehicle Display Systems. JAMA will continue to work towards the optimal guideline.
