“…They found that feedback of any type decreases the final positioning time (between entering the target an selecting it) but has no significant effect on overall completion time. Regarding cursor shape, Po et al [17] compared a circle cursor and four arrow cursors (upper-left, upperright, lower-left and lower-right) and showed that (i) an arrow cursor is more efficient when it is oriented in the direction of movement and that (ii) a circle cursor is the most efficient on average and its performance is independent of the movement angle.…”

Pointing on screen edges is a frequent task in our everyday use of computers. Screen edges can help stop cursor movements, requiring less precise movements from the user. Thus, pointing at elements located on the edges should be faster than pointing in the central screen area. This article presents two experiments to better understand the foundations of "edge pointing". The first study assesses several factors both on completion time and on users' mouse movements. The results highlight some weaknesses in the current design of desktop environments (such as the cursor shape) and reveal that movement direction plays an important role in users' performance. The second study quantifies the gain of edge pointing by comparing it with other models such as regular pointing and crossing. The results not only show that the gain can be up to 44%, but also reveal that movement angle has an effect on performance for all tested models. This leads to a generalization of the 2D Index of Difficulty of Accot and Zhai that takes movement direction into account to predict pointing time using Fitts' law.

“…For example, the cursor might turn into a pointing hand if it is over an hyper-link or into a typewriter cursor if it is inside an editable text area. However, although there are several studies on 2D cursor shapes [20,21], they are only focused on 2D content.…”

The selection and manipulation of 3D content in desktop virtual environments is commonly achieved with 2D mouse cursor-based interaction. However, by interacting with image-based techniques we introduce a conflict between the 2D space in which the 2D cursor lays and the 3D content. For example, the 2D mouse cursor does not provide any information about the depth of the selected objects. In this situation, the user has to rely on the depth cues provided by the virtual environment, such as perspective deformation, shading and shadows.In this paper, we explore new metaphors to improve the depth perception when interacting with 3D content. Our approach focus on the usage of 3D cursors controlled with 2D input devices (the Hand Avatar and the Torch) and a pseudo-motion parallax effect. The additional depth cues provided by the visual feedback of the 3D cursors and the motion parallax are expected to increase the users' depth perception of the environment. The evaluation of proposed techniques showed that users' depth perception was significantly increased. Users were able to better judge the depth ordering of virtual environment. Although 3D cursors showed a decrease of selection performance, it is compensated by the increased depth perception.

“…Po, Fisher, and Booth (2005) remark that modern GUIs are still using more or less the same original cursors that came about in the mid 1970's. These cursors were partially crafted based on the hardware constraints of the time.…”

Collaboration often relies on all group members having a shared view of a single-user application. A common situation is a single active presenter sharing a live view of her workstation screen with a passive audience, using simple hardware-based video signal projection onto a large screen or simple bitmap-based sharing protocols. This offers simplicity and some advantages over more sophisticated software-based replication solutions, but everyone has the exact same view of the application. This conflicts with the presenter's need to keep some information and interaction details private. It also fails to recognize the needs of the passive audience, who may struggle to follow the presentation because of the amount of interaction details, display clutter or insufficient familiarity with the application.Views that cater to the different roles of the presenter and the audience can be provided by custom solutions, but these tend to be bound to a particular application. This thesis describes a general technique and implementation details of a prototype system that allows standardized role-specific views of existing single-user applications and permits additional customization that is application-specific with no change to the application source code. Role-based policies control manipulation and display of shared windows and image buffers produced by the application, providing semi-automated privacy protection, relaxed verbosity and added visual cues to meet both presenter and audience needs.The system's prototype was evaluated in a formal user study, in a task training scenario using a shared view. The study showed that adding visual cues improves accuracy, while privacy filters do not result in performance penalties but can even assist viewers. ContentsAbstract .
