Abstract
Abstract The present study investigated the effects of different joint-based interactive methods and control-display gains on performance and usability for distant pointing by using ISO 9241–9 test procedures. Ten healthy participants performed multi-directional tapping tests with three joint-based interactive methods (wrist-, elbow-, and shoulder-based interactive methods) and three CD gains (0.6, 1.0, and 1.7) by using an air mouse as the input device. The experimental results indicated that the wrist-based interactive method is a better interactive method for tasks where pointing speed is the highest priority and the 1.7 CD gain, which was found to cause significantly higher MT and ER and lower TP and subjective usability rating scores than wrist- and elbow-based pointing, should be avoided in distal pointing tasks. Furthermore, the best suggested CD gains for the wrist-based interactive method are 1.0 and 1.7. The recommended CD gain setting of the elbow-based interactive method is 0.6, and 1.0 CD gain is feasible for the shoulder-based interactive method.

Abstract Human eyes exhibit different characteristic patterns during different virtual interaction tasks such as moving a window, scrolling a piece of text, or maximizing an image. Human-computer studies literature contains examples of intelligent systems that can predict user’s task-related intentions and goals based on eye gaze behavior. However, these systems are generally evaluated in terms of prediction accuracy, and on previously collected offline interaction data. Little attention has bee...

Learning through modules on a tablet helps students participate effectively in learning activities in classrooms and provides flexibility in the learning process. This study presents the design and evaluation of an application that is based on handwriting recognition technologies and e-content for the developed learning modules. The application aims to support the handwriting learning process in first grade and provides an efficient interface to the learning modules through the natural form of h...

Abstract User interfaces based on touchless hand gestures have advantages over conventional user interfaces in a variety of scenarios. However, they still have challenging problems to be researched, such as the design and evaluation of them in order to obtain satisfactory results. The classical approach of involving users to choose gestures or analyze interface designs needs to be complemented with predictive evaluations for cases in which those user-based methods are inapplicable or expensive t...

Pointing is one of the more meaningful gestures in human expression. In this article, deictic and head pose pointing methods are evaluated as interaction means, with the objective of comparing their efficiency and delivered comfort, usability, and user experience to apply them to the deployment of services in smart spaces. Standard tools and questionnaires are applied in a user study with 20 individuals who have tried a Kinect V2-enabled pointing system to a) complete a multidirectional Internat...

Pointing at displays from a distance is becoming common in both work and domestic environments. Ray-casting interaction is easy for novices to learn and understand, but this technique can cause physiological fatigue. To address this issue, the present study aims to investigate the issue of fatigue caused by joint-based pointing methods and Control-Display gains (CD gains) via Fitts' task. Ten healthy subjects participated in the experiment and performed multi-directional tapping tests with three...

This study aims to evaluate three commercial virtual reality VR display devices on the market via a 3D Fitts's task. In addition, a symptom questionnaire was used to assess the severity of cybersickness symptoms induced by these displays. Ten participants performed repetitive pointing tasks over different conditions of varying display devices, movement directions, and indices of difficulty. On the basis of the results, the projection display obtained the best task performance with the lowest mov...

Abstract Many object pointing and selecting techniques for large screens have been proposed in the literature. There is a lack of quantitative evidence suggesting proper pointing postures for interacting with stereoscopic targets in immersive virtual environments. The objective of this study was to explore users' performances and experiences of using different postures while interacting with 3D targets remotely in an immersive stereoscopic environment. Two postures, hand-directed and gaze-direct...

Pointing at displays from a distance is becoming a common method of interacting with computer applications and entertainment systems, using devices such as the Wii Remote, the PlayStation Move controller, or the Microsoft Kinect. These systems often implement relative forms of ray-cast pointing, in which the user simply points a hand-held input device towards targets on the screen. Ray-casting interaction is easy for novices to learn and understand, but this technique often suffers from accuracy...

Abstract Remote Gesture Pointing (RGP) has been developed as a means for controllers to perform pointing operations when the controller of a device is required to move about during the task and is not normally stationed at a fixed location. Some devices in RGP environments have been developed for such purposes, but to date little research has been reported. To contribute to addressing this issue, our study examines the muscle fatigue problems in RGP environments and proposes an orthopedic applia...

The increasing use of remote pointing devices in various application domains is fostering the adoption of pointing enhancement techniques which are aimed at counterbalancing the shortcomings of desk-free interaction. This paper describes the strengths and weaknesses of existing methods for ray pointing facilitation, and presents a refinement of Smoothed Pointing, an auto-calibrating velocity-oriented precision enhancing technique. Furthermore, the paper discusses the results of a user study aime...
