3. Information Presentation PrinciplesEU Statement of Principles AAM-guideline comment3.1 Visually displayed information shouldbe such that the driver can assimilate itwith sequential glances that are briefenough not to adversely affect driving.3.2 Where available, internationally agreedupon standards relating to legibility,audibility, icons, symbols, words,acronyms or abbreviations, should beused.3.3 Information relevant to the driving taskshould be timely and accurate.2.1 Systems with visual displays should bedesigned such that the driver cancomplete a desired task with sequentialglances that are brief enough not toadversely affect driving.Criteria Alternative A:A visual or visual manual task ... shouldbe designed to the following criteriaA1: single glance duration < 2sA2: total glance time < 20s for taskcompletionCriterion Alternative B:influence on driving performanceshould not exceed influence of a“reference task” under the sameconditions2.2 Where available, internationally agreedupon standards relating to legibility,audibility, icons, symbols, words,acronyms or abbreviations, should beused. Where no standards exist,relevant design guidelines or empiricaldata should be utilized2.3 Available information relevant to thedriving task should be timely andaccurate under routine drivingconditionsadditional criterion: timeliness and accuracyof information are task and subsystemspecificdisagree, since1. scope of principle is extended frominformation presentation to the wholeinteraction with the system2. concept of task is questionable sincedefinition is unclear and dependent ondriver behaviour3. proposed criteria and verificationprocedures address the completeinteraction - not information presentationitself (apart from A1):Criterion A2 refers to the total task,Criterion B describes the overall HMIeffecton driving performanceESoP wording should be kept in order tokeep up the distinction betweeninformation presentation and interactionprinciples and to avoid the introductionof simplistic pass/fail criterianeeds discussionno substantial change, relevant standardsneed to be discussedneeds discussionno substantial change, value added?3.4 The system should not presentinformation which may result inpotentially hazardous behaviour by thedriver or other road users3.5 The system should not produceuncontrollable sound levels liable tomask warnings from within the vehicleor outside.- [not in AAM guideline] disagree,principle should be kept, addressesinformation content2.4 The system should not produceuncontrollable sound levels liable tomask warnings from within the vehicleor outside or to cause distraction orirritationdisagree,ESoP addresses systems whose sound levelis uncontrollable by the driver – AAMinterpretation: sound level must not beuncontrollable, leading to a redundantmeaning to ESoP Interaction principle 4.8Page 320 of 490
