19、ISO 15007-1, which defines key terms and parameters for the assessment of the visual impact on driver visual behaviour of TICS (Traffic Information Control Systems), and other vehicle tasks or on-board systems.ISO/TS 15007-2 supports ISO 15007-1 by giving guidance on equipment and procedures that ca

20、n be used in a practical TICS evaluation, with recommendations on how to interpret selected metrics (standards of measurement) of visual behaviour.

21、 information and control systems Part 2: Equipment and procedures1 ScopeThis Technical Specification gives guidelines on equipment and procedures for analysing driver visual behaviour, intended to enable assessors of transport information and control systems (TICS) to plan evaluation trials; specify

22、 (and install) data capture equipment, and; validate, analyse, interpret and report visual-behaviour metrics (standards of measurement).It is applicable to both road trials and simulated driving environments.2 Normative referencesThe following documents, in whole or in part, are normatively referenc

23、ed in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 15007-1, Road vehicles Measurement of driver visual behaviour with respect

24、 to transport information and control systems Part 1: Definitions and parameters3 Terms and definitionsFor the purposes of this document, the terms and definitions given in ISO 15007-1 apply.4 Evaluation and trial planning4.1 Subject selectionEvaluation trials of TICS applications should use a repre

25、sentative sample from the target population for the specific TICS. This driver sample should be categorized by age, gender, visual ability (including colour vision deficiencies, as well as whether and what type of corrective lenses are required to drive) and driving experience.4.2 Trial procedures4.

26、2.1 GeneralAssessment of driver visual demand can be carried out in relation to many forms of TICS applications and road environments. Therefore, consideration should be given to the following factors influencing driver visual behaviour.TECHNICAL SPECIFICATION ISO/TS 15007-2:2014(E) ISO 2014 All rig

27、hts reserved 1PD ISO/TS 15007-2:2014ISO/TS 15007-2:2014(E)4.2.2 Roadway/traffic specificationAn appropriate operational environment for the specific TICS application under evaluation should be chosen. The type of roadway and likely traffic conditions to be encountered should be defined within the tr

28、ial (or study). This may entail defining and documenting the roadway geometry, signals, and surroundings as well as describing the driving scenarios that participant will experience (including speeds of travel, manoeuvres, traffic densities, movement of traffic, and so forth).4.2.3 Vehicle specifica

29、tionExperimental apparatus used to represent the driving task should be described as fully as practicable.EXAMPLE Document the make and model of the road vehicle employed or the driving simulator characteristics employed (including key parameters of the vehicle dynamics model, whether the simulator

30、has a fixed- or moving-base, the breadth of its field of view, etc.).4.2.4 TICS specificationThe characteristics of the TICS should be reported.EXAMPLE Type, position and image quality of a visual display (resolution, contrast, colour-rendition, reflectivity/glare).4.2.5 Subject trainingTrial object

31、ives will determine the need for subject training in the use of the TICS. Assuming that some form of training is required, subjects should receive clear and consistent guidance. The tasks and subtasks associated with the TICS should be fully explained to the subject and the limitations of responsibi

32、lity and pacing of these between the driver and experimenter should be specified. Each subjects familiarity with the TICS prior to the trial should be reported. When determining the usability of the TICS device, consideration should be given to the level and assessment of training required.4.2.6 Dat

33、a exclusionControl procedures for individual evaluation trials within an experimental programme should include guidelines for the conditions under which the trial is to be terminated.EXAMPLE Trial aborted for failure to complete a task or subtask: document how this is to be recorded or how the trial

34、 is to be re-scheduled.4.2.7 Experimental conditions, tasks, subtasks, sub-subtasks, and relationship4.2.7.1 Experimental conditionThis is considered to encompass all visual behaviour of the driver during an experimental session.EXAMPLE The distributions of visual scanning to all specified areas of

35、interest of the visual scene (including the TICS), from the specified start of a test route to its specified end.Researchers will need the flexibility to define experimental conditions that are relevant for their research goals. However, when studies involve examining glance patterns for secondary t

36、asks while driving, the following experimental conditions may be useful for planning and for performing the research. The following terms are introduced because they define intervals of time and behaviour that may be of particular interest when evaluating a TICS and, hence, in analysing the glance d

38、tering a destination into a route guidance system.4.2.7.3 SubtaskA sequence of interactions undertaken to achieve a sub goal of the task (often one specific interaction). Glance behaviour may be measured over this (shorter) duration of the subtask.EXAMPLE When entering a destination into the route g

39、uidance system, all visual behaviour associated with entering the “city name” portion of the destination.4.2.7.4 Sub-SubtaskOperations or interactions with lower-level subtask elements (e.g. individual controls or screens).EXAMPLE On the route guidance system, glance behaviour associated with the su

40、b-subtask of “verify the city name appeared” on destination entry screen.4.2.7.5 RelationshipThe relationship between an experimental condition, a task, a subtask and a lower level subtask element is graphically represented in Figure 1.Annotation: Users of this standard may wish to consult reference

42、quipment5.1 GeneralThe following gives practical advice on the use of data recording equipment to monitor driver visual demand.5.2 Eye-Tracking equipmentIn general, there are two different methodologies for recording eye-tracking data: Head-mounted eye-tracking systems. Remote eye-tracking systems.4

43、 ISO 2014 All rights reservedPD ISO/TS 15007-2:2014ISO/TS 15007-2:2014(E)5.2.1 Head-mounted eye-tracking systemsWith head-mounted eye-tracking systems, the subject wears components of the eye-tracking system directly on the head. The components necessary for the eye-tracking are mounted on a helmet,

44、 a cap or on a device similar to glasses. Head-mounted eye-trackers may consist of the following components: Scene camera: this camera records what the subject can see. Eye camera: this camera records at least one eye.NOTE 1 The eye can be recorded directly or via an infrared (IR) reflective mirror.

45、NOTE 2 Calibration of eye camera to scene camera is necessary to transform the x- and y-coordinates from the eye camera coordinate system to the scene camera coordinate system. Thereby the head-mounted eye-tracking system is able to indicate in the scene camera view where the subject is looking. Inf

46、rared LED: the infrared LED typically makes the eye visible in the infrared spectrum. Thereby the system becomes more independent and robust from the surrounding lighting conditions.5.2.2 Remote eye-tracking systemsWith remote eye-tracking systems the glance behaviour is recorded by at least one cam

47、era mounted in some location that can record the drivers eyes, such as the dashboard.Remote eye-trackers (and/or image recording systems) may consist of the following components: Eye camera: at least one camera is directed to the drivers face to capture where the subject is looking Scene camera: the

48、 scene camera records the road scene ahead.NOTE 1 Calibration of eye-camera to scene-camera is necessary to transform the x- and y-coordinates from the eye-camera coordinate system to the scene-camera coordinate system. Thereby the remote eye-tracking system is able to indicate in the scene-camera v

49、iew where the subject is looking. Infrared LED: the infrared LED typically makes the eye visible in the infrared spectrum. As a result, the system becomes more independent and robust from the surrounding lighting conditions.NOTE 2 Remote systems include conventional methods of capturing glance behaviour on video.5.2.3 Additional componentsThe following additional components are typically required: Computer unit for storage and control Eye-tracking software: the eye-tracking software records, processes and s
