“…In this study, we learned about the essential target tasks and the most commonly used freehand gestures (i.e., the top gestures) for those tasks in a gestural VR shopping application. Different from standard gesture elicitation study procedure [31][32][33][34][35][36], we asked two groups of 30 participants to design gestures for the ten system tasks in two independent elicitation studies. The experimental results verified our hypothesis that the user-defined gesture set produced solely from a single elicitation procedure may be trapped in the local minima and fail to uncover gestures that may be better suited for given target tasks.…”

“…However, for other tasks, such as Task 6-Enlarge an object and Task 7-Shrink an object, one may obtain different top gestures in spite of the relatively high agreement scores in two independent gesture elicitation studies. In this case, the popular "frequency ratio" method and the "winnertake-all" strategy adopted by most standard elicitation studies [28,[31][32][33][34][35][36] may not be effective due to conflicts.…”

“…However, most standard gesture elicitation studies adopted a "1-to-1" experimental protocol, which means participants were required to design only a single gesture for each task [11,[31][32][33][34][35][36]. In practice, such approach inevitably encounters the legacy bias problem [37] because when end-users are involved in gesture design their gesture choices are often biased by their experience with prior interfaces (e.g., graphical user interfaces) and technologies (e.g., multitouch-based techniques) that have recently been standard on traditional personal computers (PCs) or mobile phones.…”

Compared to brick-and-mortar retail stores, online shopping has many advantages, such as unrestricted shopping hours as well as a greater focus on functionality and more efficient information retrieval. However, the current online shopping systems only present products using text and images, and they cannot provide end-users with an immersive shopping experience [1-4]. For end-users, the product representations in the form of images and text in scrollable lists are difficult to understand, i.e., end-users cannot obtain a clear sense of the size, weight, and shape of the product. In addition, the unnatural interaction techniques, such as scrolling a list or navigating through product

“…Input vocabularies are classified according to their underlying mental models and clustered into three classes ( imitative , instrumented and intelligent ). In terms of intuitiveness of input vocabularies, single metaphor based gestures and gestures based on multiple metaphors for UAV are presented [ 95 ]. The proposed gestures are evaluated (using a Kinect sensor) in a user study.…”

Modern hardware and software development has led to an evolution of user interfaces from command-line to natural user interfaces for virtual immersive environments. Gestures imitating real-world interaction tasks increasingly replace classical two-dimensional interfaces based on Windows/Icons/Menus/Pointers (WIMP) or touch metaphors. Thus, the purpose of this paper is to survey the state-of-the-art Human-Computer Interaction (HCI) techniques with a focus on the special field of three-dimensional interaction. This includes an overview of currently available interaction devices, their applications of usage and underlying methods for gesture design and recognition. Focus is on interfaces based on the Leap Motion Controller (LMC) and corresponding methods of gesture design and recognition. Further, a review of evaluation methods for the proposed natural user interfaces is given.

“…However, most of these works propose limited solutions to this problem, mainly using out of the shelf products with default settings as in refs. [21][22][23][24][25], which reduce the flexibility of the proposal. Furthermore, safety measures for limiting hazardous gestures are not considered, compromising the safety of operators, specially for novice users.…”

SUMMARY This paper introduces an intuitive and safe command approach for a quadrotor, where inertial and muscular gestures are used for semi-autonomous flight. A bracelet composed of gyroscopes, accelerometers, and electromyographic sensors is used to detect user gestures, then an algorithm is proposed to interpret the signals as flight commands. The main goal is to provide a wearable, easy-to-handle human–machine interface for users a to safely command this kind of vehicles, even for inexpert operators. Safety measures are incorporated in the scheme to further enhance the user’s experience. Experimental tests are performed to validate the proposal.
