Vision-based dynamic hand gesture recognition techniques and applications: A review
Hand gesture recognition is an area in computer science that focuses on utilizing mathematical algorithms to analyze human gestures. The aim of this study is to perform a review evaluating related input devices, techniques, limitations and problems of dynamic hand gesture recognition using vision-based methods. More precisely, the hand gesture recognition process is divided into four stages: (a) input image, (b) segmentation, (c) feature extraction and (d) classification/recognition. Gesture control is the ability to acknowledge and interpret human body movements using a variety of gestures or motions made in the air by interacting and controlling devices without having the need to physically touch them. The Single Camera, Leap Motion Controller (LMC) and Microsoft Kinect are the three vision-based hand gestures devices that are compared in this review paper. We found out that the Single Camera is able to perform and achieve an accuracy rate of more than 95%. Besides, this paper not only is able to differentiate and compare the accuracy rate between the input devices, but also between the techniques applied which consists of (a) Hidden Markov Model, (b) Dynamic Time warping and (c) Neural Network including their advantages as well as the disadvantages. The applications that are used in vision-based dynamic hand gesture recognition are presented
The intelligence between the influence of AR technical ideological and political courses on the different characteristics of college students
In the contemporary educational ecosystem, Augmented Reality (AR) technology is marking its prominence across diverse disciplines globally, and China has been an active adopter. By integrating AR, educators, especially those handling ideological and political courses, can elevate their teaching methodologies, rendering them more interactive and engaging. For instance, traditionally static textbook content can be transformed into interactive elements, allowing students a tactile experience, while intricate theoretical constructs can be elucidated through dynamic video demonstrations. Such immersive approaches not only enhance comprehension but also significantly boost students’ enthusiasm and classroom involvement. Beyond mere content delivery, AR opens up avenues for innovative classroom exercises and evaluations. Within the framework of ideological and political courses, students, by leveraging AR, can simulate real-world scenarios, ensuring that knowledge transcends theory and is solidified through practical application. The essence of our research underscores the pivotal role of AR in rejuvenating pedagogical strategies, fostering improved learning outcomes, and ensuring a holistic understanding of intricate ideological and political concepts. Keywords: five major personalities; AR learning system; ideological and political learning analysis
A comparative study of interactive segmentation with different number of strokes on complex images
Interactive image segmentation is the way to extract an object of interest with the guidance of the user. The guidance from the user is an iterative process until the required object of interest had been segmented. Therefore, the input from the user as well as the understanding of the algorithms based on the user input has an essential role in the success of interactive segmentation. The most common user input type in interactive segmentation is using strokes. The different number of strokes are utilized in each different interactive segmentation algorithms. There was no evaluation of the effects on the number of strokes on this interactive segmentation. Therefore, this paper intends to fill this shortcoming. In this study, the input strokes had been categorized into single, double, and multiple strokes. The use of the same number of strokes on the object of interest and background on three interactive segmentation algorithms: i) Nonparametric Higher-order Learning (NHL), ii) Maximal Similarity-based Region Merging (MSRM) and iii) Graph-Based Manifold Ranking (GBMR) are evaluated, focusing on the complex images from Berkeley image dataset. This dataset contains a total of 12,000 test color images and ground truth images. Two types of complex images had been selected for the experiment: image with a background color like the object of interest, and image with the object of interest overlapped with other similar objects. This can be concluded that, generally, more strokes used as input could improve image segmentation accuracy

System Usability Scale Formula as Alternative for Calculating Composite Score of Likert-type Items
Since its conception, Likert Scales have been used
extensively in various fields. There are many ways to describe data
obtained with Likert scales. In Human Factors research, System
Usability Scale (SUS) is a widely adapted Likert Scale instrument
to assess the usability of various products and systems.
Researchers often have the tendency to modify SUS to fit their
context of use, leading to various versions of SUS. Calculation of
the composite score for SUS instrument does not involve
computation of arithmetic mean/sum and re-coding of statements.
SUS formula obtains the score for each Likert-type items and
convert them into a single scale range from 0 to 100. Although SUS
is a popular instrument, there is no formula introduced to
facilitate the calculation of scale. This article aims to introduce a
formula to facilitate the calculation of various versions of SUS with
different number of items, number of positive and negative
statements, as well as scale size. Although primarily meant for SUS
practitioners, the formula presented can be used for any
instrument adapting Likert-type items should the researchers
decide to transform responses into 0-100 scale instead of
computation of mean or sum for various statistical analyses. The controversial computation of mean for Likert Scales has been subjected to decades of debate. This article demonstrates an alternate method to calculate composite score of Likert-type items based on calculation of SUS. Results show the formula yield the same results and perfect relationship with mean and sum for various tests, indicating it can be used as an alternative to mean
and sum as a composite score of Likert-types items
