21、014Road vehicles Measurement of driver visual behaviour with respect to transport information and control systems Part 2: Equipment and procedures 1 Scope This Technical Specification gives guidelines on equipment and procedures for analysing driver visual behaviour, intended to enable assessors of
22、transport information and control systems (TICS) to plan evaluation trials; specify (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 Norma

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments)
24、applies. ISO 15007-1, Road vehicles Measurement of driver visual behaviour with respect to transport information and control systems Part 1: Definitions and parameters 3 T erms a nd definiti ons For the purposes of this document, the terms and definitions given in ISO 15007-1 apply. 4 Evaluation and
25、 trial planning 4.1 Subject selection Evaluation trials of TICS applications should use a representative 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
26、 type of corrective lenses are required to drive) and driving experience. 4.2 Trial procedures 4.2.1 General Assessment 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 i
27、nfluencing driver visual behaviour. TECHNICAL SPECIFICATION ISO/TS 15007-2:2014(E) ISO 2014 All rights reserved 1PD ISO/TS 15007-2:2014ISO/TS 15007-2:2014(E) 4.2.2 R oad w a y/tr affic sp ecification An appropriate operational environment for the specific TICS application under evaluation should be
28、chosen. The type of roadway and likely traffic conditions to be encountered should be defined within the trial (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
29、speeds of travel, manoeuvres, traffic densities, movement of traffic, and so forth). 4.2.3 V ehicle specificatio n Experimental 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 si
30、mulator characteristics employed (including key parameters of the vehicle dynamics model, whether the simulator has a fixed- or moving- base, the breadth of its field of view, etc.). 4.2.4 TIC S specification The characteristics of the TICS should be reported. EXAMPLE Type, position and image qualit
31、y of a visual display (resolution, contrast, colour-rendition, reflectivity/glare). 4.2.5 Subject training Trial objectives 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
32、 tasks and subtasks associated with the TICS should be fully explained to the subject and the limitations of responsibility 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
33、 usability of the TICS device, consideration should be given to the level and assessment of training required. 4.2.6 Data exclusion Control procedures for individual evaluation trials within an experimental programme should include guidelines for the conditions under which the trial is to be termina
34、ted. EXAMPLE Trial aborted for failure to complete a task or subtask: document how this is to be recorded or how the trial is to be re-scheduled. 4.2.7 Experimental conditions, tasks, subtasks, sub-subtasks, and relationship 4.2.7.1 Experimental condition This is considered to encompass all visual b
35、ehaviour of the driver during an experimental session. EXAMPLE The distributions of visual scanning to all specified areas of 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
36、 conditions that are relevant for their research goals. However, when studies involve examining glance patterns for secondary tasks while driving, the following experimental conditions may be useful for planning and for performing the research. The following terms are introduced because they define
37、intervals of time and behaviour that may be of particular interest when evaluating a TICS and, hence, in analysing the glance data associated with a TICS.2 ISO 2014 All rights reservedPD ISO/TS 15007-2:2014ISO/TS 15007-2:2014(E) 4.2.7.2 Task refers to a sequence of interactions undertaken to achieve
38、 a goal glance behaviour may be measured over the duration of a task. EXAMPLE All visual behaviour occurring during the task of entering a destination into a route guidance system. 4.2.7.3 Subtask A sequence of interactions undertaken to achieve a sub goal of the task (often one specific interaction
39、). Glance behaviour may be measured over this (shorter) duration of the subtask. EXAMPLE When entering a destination into the route guidance system, all visual behaviour associated with entering the “city name” portion of the destination. 4.2.7.4 Sub-Subtask Operations or interactions with lower-lev
40、el subtask elements (e.g. individual controls or screens). EXAMPLE On the route guidance system, glance behaviour associated with the sub-subtask of “verify the city name appeared” on destination entry screen. 4.2.7.5 Relationship The relationship between an experimental condition, a task, a subtask
41、 and a lower level subtask element is graphically represented in Figure 1. Annotation: Users of this standard may wish to consult references on hierarchical task analysis for guidance on how to decompose a task (e.g. see Reference 4).

43、nt In general, there are two different methodologies for recording eye-tracking data: Head-mounted eye-tracking systems. Remote eye-tracking systems.4 ISO 2014 All rights reservedPD ISO/TS 15007-2:2014ISO/TS 15007-2:2014(E) 5.2.1 Head-mounted eye-tracking systems With head-mounted eye-tracking syste
44、ms, 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, 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
45、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. 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 s
46、cene camera coordinate system. Thereby the head-mounted eye-tracking system is able to indicate in the scene camera view where the subject is looking. Infrared LED: the infrared LED typically makes the eye visible in the infrared spectrum. Thereby the system becomes more independent and robust from
47、the surrounding lighting conditions. 5.2.2 Remote eye-tracking systems With remote eye-tracking systems the glance behaviour is recorded by at least one camera mounted in some location that can record the drivers eyes, such as the dashboard. Remote eye-trackers (and/or image recording systems) may c
48、onsist 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 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
49、 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 view 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 com
