Evaluating Eye Tracking with ISO 9241 - Part 9

Abstract

Abstract. The ISO 9241-9 standard for computer pointing devices proposes an evaluation of performance and comfort [4]. This paper is the first eye tracking evaluation conforming to ISO 9241-9. We evaluated three techniques and compared them with a standard mouse. The evaluation used throughput (in bits/s) as a measurement of user performance in a multi-directional point-select task. The "Eye Tracking Long" technique required participants to look at an onscreen target and dwell on it for 750 ms for selection. Results revealed a lower throughput than for the "Eye Tracking Short" technique with a 500 ms dwell time. The "Eye+Spacebar" technique allowed participants to "point" with the eye and "select" by pressing the spacebar upon fixation. This eliminated the need to wait for selection. It was the best among the three eye tracking techniques with a throughput of 3.78 bits/s, which was close to the 4.68 bits/s for the mouse.

Exploring the effects of image persistence in low frame rate virtual environments

“…Figure 3 shows the sequence of targets. This selection task was used because it is a standard that has been utilized in previous studies [43,9]. We decided to test three target widths to reflect 1°, 2°and 3°of visual angle.…”

Assessment of functional parameters and comfort of a new computer mouse as compared with other types of input devices

“…A pointing task defined according to Standard No. ISO-9241-9: 2000 [12] and set by the software [13] was performed by participants for testing each device. Standard No.…”

Evaluation of a Low-cost Eye Tracking System for Computer Input

“…The evaluation of performance for low-cost devices in this research used a multi-direction point-select task of the ISO 9241-9 [20] which the standard for computer pointing devices. The authors developed a test based on visual search and selection to change the ground colour on a circular menu layout.…”

“…Most of them use Fitts' law and ISO 9241-part 9 standard to calculate the index of performance (IP) [20]. The IP is measured in bit per second (bits/s), which includes both the speed and accuracy of users' performance.…”
