“…The user again clicked the starting target, and after a random amount of time the end target would appear somewhere along a circle centered on the starting target with a radius equal to the D. The unpredictable stimulus position around the circle avoided the potential premovement of participants before the end target appeared and excluded the effect of the approaching angle (Oehl et al, 2007). After the participant visually acquired the end target, the user again clicked within the starting target and moved to click the end target, as quickly and accurately as possible.…”

“…Procedure and design. In Experiment 2, we used the serial pointing task, which is similar to the method from Oehl et al (2007) and Fernandez and Bootsma (2004). In the task, the starting target was still in the center of the screen.…”

“…The bandwidths were disproportionally lower in the smallest display size condition across all ID values. Oehl, Sutter, and Ziefle (2007) conducted a study to determine the relevance of display size on MT and ER. They found that with identical ID values, determined by six pairs of proportionally scaled W and D and across the three display sizes (6 × 8, 12 × 16, and 18 × 24 cm), that the smallest display size yielded significantly longer MT and a higher ER.…”

Updating Fitts' Law to Account for Restricted Display Field of View Conditions

The field of view (FOV) restricted displays are becoming more prevalent in daily use, such as touch-screen-based smart phones; ultramobile PCs; and, to some extent, head-mounted displays. All of these displays occupy significantly smaller portions of a user's FOV compared to standard desktop and laptop displays. Prior research has shown that there is an effect of display size, which is related with display FOV, on movement time (MT) when performing pointing tasks. However, there has yet to be a detailed, quantitative study of how display FOV affects MT across a wide range of FOV values. In the present study two user experiments are conducted, and it is found that Fitts' law is no longer adequate for modeling MT if the display FOV is restricted below a certain value, which we call the critical size. A new Fitts'-FOV model isproposed to extend Fitts' law beyond this critical size to restricted display FOV conditions. The results showed that the new model works as both a descriptive and a predictive model for restricted display FOV conditions.

Abstract. Touch-screen smart phones have gradually occupied the market of traditional Qwerty Phones and become the mainstream products of mobile phone industry. However, few ergonomics research has been conducted on the touch screens of smart phones, while it has led to tendosynovitis among users owing to the overuse of thumbs. Sizes of smart phones in market range from 3.0 to 7.0 inches. What's more, 4.0 inches and above are the common size of current touch screens. Also, considering the users' habits, one-hand operation is preferred when the other hand is occupied. This paper has collected hand parameters of 80 subjects and has adopted an experiment which includes the performance testing and surveys of subjective evaluation by means of usability evaluation. After analysing correlation between touch-screen sizes and operation performances, the result indicates that under one-hand operation, the size of touch screen affects the operation performance significantly. However, it's hard to implement one-hand operation if the touch-screen size is over 5.7 inches. Additionally, the thickness of smart phones affects the degree of comfort remarkably.

“…However, these guidelines are very general and do not have concrete examples of UI components to be used based on specific models of handheld devices. Oehl et al [2] looked into the correlation between the size of a screen's display to the difficulty of the pointing task influenced by the size of the target for touch screen displays using a stylus pen. This differs from our research since instead of evaluating the sizes of target components on the screen, we focus on the actual UI components that should be used in order to easily input information.…”

Abstract. With the advent of touch screen phones, good UI design and simplified input methods for applications running on such devices are important factors that contribute to its popularity and success. The goal of this research is to evaluate different user interface designs and input methods for mobile phones with touch screen capability. In order to do this, two prototypes of a simple social networking application were implemented using a G1 phone that runs the Android platform. A user study has been conducted to compare different input techniques and UI designs and evaluate their usability.
