Adaptive interaction methods in speech user interfaces

This paper explores the basic interaction methods and techniques in intelligent decision support systems (IDSS) based on PMCDSS (project management and control DSS) that is our developed project during last six years. From that we found that a computer system has to possess reasonable high-level interaction methods, styles and techniques so as to increase the system function and availability. In the paper, we introduce the PMCDSS as a case study first, and then focus on the role of interaction in system running and its requirements. Further we give the summary of interaction methods and techniques in system analysis and design, such as object-oriented modelling, direct-manipulation style, combining dialogue with computing and determining of interaction structure and interactive points. The aim of this paper is to emphasise the interactive roles, not only to envisage the interface design but also to devote substantial attention to the deep level of human intelligence and thought interacting with machine. >

Exploring Self-Care Needs Of African American And Hispanic/Latino Heart Failure Patients Outside Clinical Setting

At the time of this paper, the advances in light field technology already offer 3D displays that immerse the users without the need for additional viewing devices. Despite the numerous advantages and attractive capabilities of such glasses-free 3D displays, their user interface methods are quite complicated and they are currently underwhelming when compared to conventional 2D displays, due to the fact that visual feedback can only be rendered sharply on the emission surface of light field displays. The sharp rendering of user interfaces is a necessity, as blur may hinder their fundamental functions. When it comes to 2D displays, many user interaction techniques and interfaces have been devised. Rendering a user interface on a 2D display could be done in various ways, such as rendering overlays on top of the rendered scene, or by using billboards. These are extensively used in modern video games. User interaction methods have proven their importance and added efficiency to virtual environments throughout the years. Due to their overall value and usefulness, interaction techniques develop immediately as new types of displays arise. With the recent advancements in visualization technologies, user interfaces have been redesigned for use in AR, VR and MR visualization. This includes on-screen augmentation, which enables interaction with visual content on the screen. Although light field displays contain immense potentials, only basic user interfaces have been devised thus far, including FOX (Focus Sliding surface), which grants users the option to scale and to rotate 3D objects. In this paper, we visualize the theater model on real light field displays and we test the different interactions by means of a monitor room. The theatre model is analogous to real-life theatres, where viewers may observe the theatrical presentation on the stage from various angles. The motivation to choose the theater model was the fact that light field visualization similarly allows multiple simultaneous viewers within its field of view, in which the content can be observed in an angle- dependent manner. Moreover, from the users’ perspective, the theater model is thus familiar and it provides high-quality visual feedback. Furthermore, theater stages encompass a lot of interactions, including rigging and flying systems, pulleys, rotating stages, lights, curtains etc. In order to test the different interaction methods on light field displays, a theater model depicting the virtual environment was implemented. Methods for rendering the monitor room and the results of the interactions are discussed in the paper, illustrated by images of the actual visualization on light field displays. It is shown that producing plausible results with no noticeable visual artifacts is challenging, yet possible. The scientific contributions of the paper also highlight the various novel user interfaces for future light field systems and services.

IntroductionExtended reality (XR) technologies, particularly gaze‐based interaction methods, have evolved significantly in recent years to improve accessibility and reach broader user communities. While previous research has improved the simplicity and inclusivity of gaze-based choice, the adaptability of such systems ‐ particularly in terms of user comfort and fault tolerance ‐ has not yet been fully explored.MethodsIn this study, four gaze‐based interaction techniques were examined in a visual search game in virtual reality (VR). A total of 52 participants were involved. The techniques tested included selection by dwell time, confirmation by head orientation, nodding and smooth pursuit eye movements. Both subjective and objective performance measures were assessed, using the NASA‐TLX for perceived task load and time to complete the task and score for objective evaluation.ResultsSignificant differences were found between the interaction techniques in terms of NASA‐TLX dimensions, target search time and overall performance. The results indicate different levels of efficiency and intuitiveness of each method. Gender differences in interaction preferences and cognitive load were also found.DiscussionThese findings highlight the importance of personalizing gaze‐based VR interfaces to the individual user to improve accessibility, reduce cognitive load and enhance the user experience. Personalizing gaze interaction strategies can support more inclusive and effective VR systems that benefit both general and accessibility‐focused populations.

Current personal single-user devices, such as smartphones, tablets, or laptops, struggle to provide the contextual awareness and coordination capabilities required for the effective collaborative analysis of large datasets. Instead, large interactive displays offer unique opportunities for co-located collaboration in meeting room environments. However, supporting collaborative interaction across multiple large displays presents distinctive challenges for interaction designers. This paper explores and compares novel interaction techniques and visualisations for large displays, with a focus on two distinct approaches for collaborative browsing and filtering of multivariate datasets: (i) shared zoomable grid view, and (ii) multiple individual network views. In order to evaluate the effectiveness of our proposed interfaces for multi-user exploratory analysis, we applied the designs to a specific use case, namely the problem of displaying research metadata from bibliographic databases to extract and collate narratives and overarching themes for research grant proposals. Following an agile design methodology, we created two prototypes incorporating our designs. We weigh the benefits and limitations of each approach by comparing them along two key dimensions: (i) methods of interaction, and (ii) visual representation. Subsequently, we compare the two design approaches and discuss the circumstances and situations that would be beneficial for use. This research and its implications are intended to inform future research exploring the design of collaborative interfaces for large-scale interaction environments.

We present a set of interaction techniques that make novel use of a small pressure-sensitive pad to allow one-handed direct control of a large number of parameters. The surface of the pressure-sensitive pad is logically divided into four linear strips which simulate traditional interaction metaphors and the functions of which may be modified dynamically under software control. No homing of the hand or fingers in needed once the fingers are placed above their corresponding strips. We show how the number of strips on the pad can be virtually extended from four to fourteen by detecting contact pressure differences and dual-finger motions. Due to the compact size of the device and the method of interaction, which does not rely on on-screen widgets or the 2D navigation of a cursor, the versatile input system may be used in applications, where it is advantageous to minimize the amount of visual feedback required for interaction.

Kalman filter with both adaptivity and robustness

Important problems in Computational Medicine exist that can benefit from the implementation of adaptive mesh refinement techniques. Biological systems are so inherently complex that only efficient models running on state of the art hardware can begin to simulate reality. To tackle the complex geometries associated with medical applications we present a general purpose mesh generation scheme based upon the Delaunay tessellation algorithm and an iterative point generator. In addition, automatic, two- and three-dimensional adaptive mesh refinement methods are presented that are derived from local and global estimates of the finite element error. Mesh generation and adaptive refinement techniques are utilized to obtain accurate approximations of bioelectric fields within anatomically correct models of the heart and human thorax. Specifically, we explore the simulation of cardiac defibrillation and the general forward and inverse problems in electrocardiography (ECG). Comparisons between uniform and adaptive refinement techniques are made to highlight the computational efficiency and accuracy of adaptive methods in the solution of field problems in computational medicine.

The current article analyses the activity of raftsmen in the capture expedition in the urban beach of Ponta Negra, Natal-RN-Brazil emphasizing the prevalence of pain/discomfort.2 MATERIALS AND METHODWork Ergonomic Analysis-WEA was used as a reference methodology (Guèrin et al, 2001; Vidal, 2003). In order to perform the modelling, observational and interactional methods were used and also specific protocols. The observational methods include systematic open observational techniques and simulations and also the use of auxiliary resources to record and further analysis, such as photographic and video cameras. The methods and interactional techniques used were the following; social and economical questionnaire, conversational actions, spontaneous and provoked verbalizations, self-confrontations and workshops (collective analysis). The diagram of painful areas was applied (Corllet et al, 1980) and the Nordic Questionnaire for the analysis of musculoskeletal symptoms (Kourinka, 1986) in search of report of pain from the raftsmen. Twenty-one raftsmen participated in the research (50% of the population). For the statistic analysis of data it was used Microsoft Office Excel 2007 and the software R(version 2.11.1).

The study was conducted to identify relevant interactive methods of teaching English. For this purpose, a survey of the level of motivation to language learning was conducted, which included a pedagogical experiment with 46 students of 7 grades of the public school “Taalim”. The results of questionnaire survey of students and observation revealed a qualitative positive growth of linguistic creativity and motivation to learn English, due to the use of role-playing games and theatrical performances in lessons. To investigate the use of interactive techniques in English language teaching and to share experiences with colleagues, a conversation was held with 23 teachers, including undergraduates using these methods. The paper examines the concepts of motivation, play, dramatization, describes the main types and methods of using interactive techniques in teaching. It was determined that games and dramatization play an important role in learning. The use of role-playing games promotes language learning, helps to increase cognitive interest in the subject, while making the learning process less difficult, develops memory and thinking, focuses attention on a particular subject, and motivates students to learn English. Dramatization technologies develop imagination, contribute to the automatic understanding of rhymed language phrases, and the development of the student’s sensory and emotional sphere. The conducted research highlighted the main features of the use of game techniques in the process of teaching English and argued that it is important to introduce games and dramatization into the learning process. Interactive methods imply the interest of students in mastering a foreign language, the desire to perceive a foreign language and learn to speak a foreign language. Linguistic creativity and motivation are enhanced through role-playing and dramatization, enabling children to overcome the language barrier and increase their own self-esteem.

This research paper details the assessment of four distinct interaction techniques for immersive training within the construction industry. The primary focus of this study was to evaluate the extent to which these methods were capable of replicating physical environment interactions within virtual environments. A common challenge associated with immersive training within construction is the need for external tools to facilitate interactions, which can negatively impact user experience. To mitigate this issue, we introduce four immersive training use cases that rely on natural interfaces for interaction. Additionally, we conducted a Quality of Experience (QoE) experiment to validate the efficacy of these use cases and interaction techniques, assessing acceptability, presence, and visual quality. Moreover, this paper presents a classification system for four distinct natural interaction methods, which we evaluated for differences in visual quality.

Objectives: The primary objective of this paper is to evaluate the correctness of the algorithm Gesture Recognition that is one of the parts of our novel method ‘Braille coded gesture pattern interaction method”; and to study the performance of Eyedroid system using the statistical methodologies. Methods/Statistical Analysis: The algorithm for gesture recognition was developed and implemented in C program to check the correctness of each step of algorithm. The gesture input parameters Swipe-Minimum-Distance, Swipe-Threshold-Velocity are defined with range of values. Varying gesture input range of values within domain and out of domain results the expected solution space. Our gesture recognition algorithm is developed for 2D touch surface. The Real time experiments were conducted for 12 blind fold subjects to observe the different versions Eyedroid-A(E-A), Eyedroid-B(E-B) of gesture recognition algorithm perceptions, being implemented in smart phones. The mean WPM for 10 trials was recorded for 12 subjects with E-A and E-B. The two tailed paired t test is performed for the mean dependent sample data of wpm. Findings: The existing 3D gesture recognition algorithm Derivative Dynamic Time Warping (DDTW) analyzed by Katarzyna Barczewska, Aleksandra Drozd, 2013 was proven to be efficient method for air fly environment. Our gesture recognition algorithm is developed for 2D touch surface found to be effective by the results of algorithm test. Gesture Recognition algorithm finds the mal gestures and the results proved that there is a significant difference in respect of blind subjects for two different Eyedroid versions. The observed data reveals E-B (mean WPM=14.95) is easy to use than E-A (mean WPM=12) as the number of words entered per minute by E-B is higher than E-A. Our Eyedroid with WPM is 14.95 is obtained to be better interactive system than the existing “Adaptive interaction Technique” system developed by Georgios Y fantidis Grigori Evreinov, 2005 confirms WPM is 12. Applications/Improvements: The implication is our Braille coded gesture pattern that enables visually challenged ones to enter more number of words than by the existing system. Our interaction method is deployable at all kinds of touchable devices.Keywords: Eyedroid-Braille Coded Gesture Pattern, Gesture Recognition Algorithm, t Test for Mobile Interaction

This paper is devoted to the description of recent and prospective decorrelation techniques used in image processing. Two classes are taken into consideration : the universal or generic methods and the adaptive methods. The first class performs signal processing independently of its specificity. These methods only rely on statistical properties of the signal. They are principally based on orthogonal transforms and subband coding. In opposition, the adaptive techniques take the a posteriori contents of the images into account. Some of them adapt universal techniques to the signal content (i.e. adaptive subband coding or hybrid methods). Others are based on feature extraction processes which include more physical entities like edges and regions. For example, object approaches attempt to describe images as collections of regions characterized by their shape and their aspect.
