“…Although these bu ons may be easy to accurately press in an ideal environment, e.g. when seated, such small and non-tactile targets can be signi cantly more di cult to interact with in other situations [4]. While the ability to perform such tasks "on the go" can be of real bene t, hazards and other changes in the surroundings do necessitate the user's brain switching a ention between the ambient environment and the device [11].…”

Smart phones and tablets are rapidly becoming our main method of accessing information and are frequently used to perform on-thego search tasks. Mobile devices are commonly used in situations where a ention must be divided, such as when walking down a street. Research suggests that this increases cognitive load and, therefore, may have an impact on performance. In this work we conducted a laboratory experiment with both device types in which we simulated everyday, common mobile situations that may cause fragmented a ention, impact search performance and a ect user perception.Our results showed that the fragmented a ention induced by the simulated conditions signi cantly a ected both participants' objective and perceived search performance, as well as how hurried they felt and how engaged they were in the tasks. Furthermore, the type of device used also impacted how users felt about the search tasks, how well they performed and the mount of time they spent engaged in the tasks.ese novel insights provide useful information to inform the design of future interfaces for mobile search and give us a greater understanding of how context and device size a ect search behaviour and user experience.

“…To find the ways to control commands, which have an affinity for the combined use with rear-touchbased cursor navigation system, is an important future work. Touch-gesture-based approach [20], [21], [22] with regarding touch-pressure [23], [24] has potential for solutions. The influence of the size of display and the weight of device on performance is also of significant interest.…”

Abstract-To improve single-handed operation of mobile devices, the use of rear touch panel has potential for user interactions. In this paper, a basic study of operational control simply achieved through drag and tap of the index finger on a rear touch panel is conducted. Since a user has to hold the handheld device firmly with the thumb and fingers, a movable range of the tip of an index finger is limited. This restriction requires a user to perform several times of dragging actions to reach a cursor to the long distance target. Considering such kinematic restriction, a technique optimized for rear operation is proposed, wherein not only the position but also the velocity of fingertip movement is regarded. Movement time, the number of dragging operation, and the throughputs of the proposed technique have been evaluated in comparison with the generic technique using Fitts's law. Experiments have been conducted to perform the target selection in the form of reciprocal 1D pointing tasks with ten participants. The combinations of two ways of holding the device (landscape and portrait) and two directions of dragging (horizontal and vertical) are considered. As a result, the proposed technique achieved the improvements of from 5 to 13% shorter movement time, from 20 to 40% higher throughputs and no deterioration of the number of dragging even for the longer distance targets. In addition, the further analysis addressed that there exists the advantageous combinations of the way of holding and the direction of dragging, which would be beneficial for better design of single-handed user interactions using rear touch.

Abstract. The touch screen of mobile devices, such as smart phones and tablets, is their primary input mechanism. While designed to be used in conjunction with its output capabilities, eyes-free interaction is also possible and useful on touch screens. One of the several possible techniques for eyes-free interaction is the virtual button method, where the screen is divided into a regular grid of buttons that can be pressed even without looking at the screen. This paper contains an exploratory study about influence factors on this interaction method. Results indicate, that not only the size of the buttons matter, but also the device orientation and user dependent factors, such as the age or general experience with touch screens. By involving small children in the evaluation we can see the validity of this approach even for the youngest users.
