Abstract

Handwriting is widely used by Chinese older adults for text input on touch screens, but their handwriting performance is relatively low in comparison to younger adults. Therefore, this study investigated how the size of the input box (15%, 30%, and 45% of the display), input method (fingers and stylus), display size (4.7 inches and 7.9 inches), and age (younger adults and older adults) influence Chinese handwriting performance and user experience. An experiment was conducted among 72 participants. A system was developed to automatically record the time of handwriting, the accuracy of handwriting, the number of protruding strokes, the number of rewritings. Besides, participants' satisfaction, preferences, and mental workload were measured through questionnaires. The results revealed significant effects of the size of the input box, age, input method, and display size on the performance indexes and subjective ratings. Accordingly, 12 design implications for improving the Chinese handwriting system were identified. [ABSTRACT FROM AUTHOR]

Abstract

In the pinyin-based Chinese input method engine (IME), its performance depends mainly on the Pinyin-to-Chinese (P2C) conversion module. Traditional methods for P2C follow a pipeline procedure, which typically suffers from error propagation. Also, the ability to input the whole sentence of pinyin-based Chinese IME for domain-specific application needs to be improved. In this paper, we propose a neural self-attention model for Pinyin Sequence to Chinese Sequence (PS2CS) conversion method, which directly infers the entire Chinese sequence by feeding the unsegmented pinyin character sequence into. Our experimental results show that the proposed method outperforms baselines and the commercial IME on specific medical domain dataset, and also achieves comparable performance on the domain-general dataset.

Abstract

The seismic wave input method based on artificial boundary substructure is clear in theory, but a large number of time history data on nodes need to be read and write, so there may exist some problems for researchers to use it directly in finite element software. The related theoretical methods are briefly introduced, the detailed ideas and implementation steps of the seismic wave input method based on artificial boundary substructures and the setting of viscoelastic artificial boundary elements in ABAQUS are presented. For viscoelastic artificial boundary elements, a method for uniform operation of equivalent physical parameters and boundary element sizes in the view interface is introduced, which is convenient and efficient. For the seismic wave input method of the artificial boundary substructure, a method of rewriting the INP files with self-written Python programs, and automatically reading and writing a large number of time history data on nodes is also introduced. Method in this paper is easy to operate and rare to make mistakes. It can quickly read the field displacement data, which is loaded on the nodes of artificial boundary substructure, also quickly read the reaction force data, which is loaded on the soil-structure dynamic interaction model as the equivalent seismic load input. The method in this paper greatly improves the pre-processing efficiency of seismic wave input, it can be widely used in the actual calculation process. [ABSTRACT FROM AUTHOR]

Abstract

Smartphones have become a common tool of daily communication, and a number of text input methods are extensively used. Qwerty and T9 are two universally used smartphone input methods that differ in user experience (UX) when entering phrases with different complexity. Phrase complexity is an indication of the number and type of characters used in a phrase. This study evaluated the impact of both experience and phrase complexity on the UX of Qwerty and T9. Thirty-two participants with different experience levels (high and low) used both Qwerty or T9 to input 40 phrases (both simple and complex phrases). Input time, speed, error rate, galvanic skin response, heart rate, and perceived usability were analyzed as dependent variables. The results indicated that Qwerty was more effective than T9 for entering complex phrases, while no obvious difference was found for simple phrases. Experience had a positive impact on the input method, and Qwerty was more helpful for participants with low experience level. Performance, physiological reaction, and perceived usability data showed similar results. These findings aid the optimal design of text input systems for smartphones. [ABSTRACT FROM AUTHOR]

Abstract

It is critical to design an adaptable and stable train timetable for long-term use in rail transit network that not only meets the dynamicity of passenger demand in different hours within one day, but also meets the uncertainty of passenger demand in different days. In this study, a scenario-based train timetabling framework is constructed to classify the possibilities of passenger demand in multiple days into a set of scenarios based on profile and volume of passenger demand. On this basis, multi-scenario demand input method (MM) is introduced to deal with the uncertainty of passenger demand, which is different from one-scenario method (OM) and average-scenario method (AM). A MM-based mixed-integer linear programming model is formulated for the bi-objective train timetabling problem under uncertain and dynamic demand at acyclic network level, in which multi-scenario small-granularity passenger demand follows actual distribution processed from historical data. The two objectives are to minimize train service cost and penalized passenger waiting time from perspectives of enterprises and passengers. Advanced and Adaptive NSGA II (AANSGA-II) is proposed to cope with the high-complexity bi-objective problem, which applies advanced population sorting based on neighborhood distance, adaptive genetic operation based on scoring mechanism and improved population initialization based on boundary individuals. The model and algorithm are testified by a small-scale numerical experiment on a virtual line and a large-scale real-world instance in Shenyang Metro network. As a result, MM-based train timetables are generally better than AM-based and OM-based train timetables in reducing generalized cost and raising robustness. Besides, AANSGA-II is more applicable than NSGA-II and CPLEX in shortening computation time at the same time of improving computation result.

Abstract

As Photovoltaic (PV) energy is impacted by various weather variables such as solar radiation and temperature, one of the key challenges facing solar energy forecasting is choosing the right inputs to achieve the most accurate prediction. Weather datasets, past power data sets, or both sets can be utilized to build different forecasting models. However, operators of grid-connected PV farms do not always have full sets of data available to them especially over an extended period of time as required by key techniques such as multiple regression (MR) or artificial neural network (ANN). Therefore, the research reported here considered these two main approaches of building prediction models and compared their performance when utilizing structural, time-series, and hybrid methods for data input. Three years of PV power generation data (of an actual farm) as well as historical weather data (of the same location) with several key variables were collected and utilized to build and test six prediction models. Models were built and designed to forecast the PV power for a 24-hour ahead horizon with 15 min resolutions. Results of comparative performance analysis show that different models have different prediction accuracy depending on the input method used to build the model: ANN models perform better than the MR regardless of the input method used. The hybrid input method results in better prediction accuracy for both MR and ANN techniques, while using the time-series method results in the least accurate forecasting models. Furthermore, sensitivity analysis shows that poor data quality does impact forecasting accuracy negatively especially for the structural approach.

Abstract

The knowledgeable, human–machine interaction sight system has the benefits of low interference, lower permeability, and no interface attachment. The smart vision system has been critical in human–computer interaction to grow and advance technologies and research. The Human–Computer Interaction based Visual Feedback System (HCIVFS) is very quickly relative to the conventional collaborative mode. Such challenges may also affect the smart machine's view and the general use of sensation communication. The fundamental premise of the computer's sight communication architecture requires practical stability. This article explores the quality of the intellectual computer's enabling communication. The Rule of Fitts has also been included in this paper for three points-to-clicks applications. The proposed algorithm's reliability is analyzed in operations, visualization, and computer vision algorithms. There is a fair recommendation for an immersive configuration of the input method for intellectual sight by computer.

Abstract

Online video games drive a multi-billion dollar industry dedicated to maintaining a competitive and enjoyable experience for players. Traditional cheat detection systems struggle when facing new exploits or sophisticated fraudsters. More advanced solutions based on machine learning are more adaptive but rely heavily on in-game data, which means that each game has to develop its own cheat detection system. In this work, we propose a novel approach to cheat detection that doesn't require in-game data. Firstly, we treat the multimodal interactions between the player and the platform as multivariate time series. We then use convolutional neural networks to classify these time series as corresponding to legitimate or fraudulent gameplay. Our models achieve an average accuracy of respectively 99.2% and 98.9% in triggerbot and aimbot (two widespread cheats), in an experiment to validate the system's ability to detect cheating in players never seen before. Because this approach is based solely on player behavior, it can be applied to any game or input method, and even various tasks related to modeling human activity., (undefined)

Abstract

Leakage of user credentials has been a conventional security threat for mobile users. In this work, we discover a new leakage threat caused by a vulnerability of the input method framework (IMF) on Android. The vulnerability lies in an IMF interface, called InputConnection, which is dynamically built to deliver user inputs from an active input method (e.g., software keyboard) to WebView, which is an essential Android component rendering Web pages. It allows the IMF interface of a WebView component to be hijacked by the app or the third-party library that embeds the WebView. Such hijacking can be exploited to steal user inputs on the Web pages loaded by the WebView. It can also eavesdrop on input fields of all the Web pages loaded by WebView without user awareness; the attack is self-contained and does not require any external dependency. It does not interrupt, delay, or change normal operations. More threateningly, this attack is easy to launch and works for most Android versions (from 4.4 to 11.0). We conduct a field study including more than 1500 tests on our developed IWH attack app. The result shows that the app can successfully steal user inputs in all the tests and identify the input strings with 98.0% accuracy. We further devise two solutions, a Web-based virtual keyboard and an IMF hijacking guardian, for mobile Web services and the Android platform, respectively. We finally prototype them on a Web server and on an Android framework, respectively, to confirm their effectiveness.

Abstract

The development of information accessibility is receiving more and more attention. One challenging task for the blind is to input Braille while by no way could they sense the location information on touch screens. The existing Braille input methods are suffering from problems including inaccurate positioning and lack of interactive prompts. In this paper, touch gestures are recognized by trained RBF network while combined gestures are modeled by Petri net that introduces logic, timing and spatial relationship description. By doing so, the Braille input concerning multi-touch gesture recognition is then implemented. The experimental results show that the method is effective and blind people can friendly Braille Input with almost real-time interaction. The input method makes full use of the inherent logic of Braille, making the blind easy to learn and remember, providing a new method for human-computer interaction between the blind and the touch screen.

Abstract

Summarization: Input methods for interaction in smartphone-based virtual and mixed reality (VR/MR) are currently based on uncomfortable head tracking controlling a pointer on the screen. User fixations are a fast and natural input method for VR/MR interaction. Previously, eye tracking in mobile VR suffered from low accuracy, long processing time, and the need for hardware add-ons such as anti-reflective lens coating and infrared emitters. We present an innovative mobile VR eye tracking methodology utilizing only the eye images from the front-facing (selfie) camera through the headset’s lens, without any modifications. Our system first enhances the low-contrast, poorly lit eye images by applying a pipeline of customised low-level image enhancements suppressing obtrusive lens reflections. We then propose an iris region-of-interest detection algorithm that is run only once. This increases the iris tracking speed by reducing the iris search space in mobile devices. We iteratively fit a customised geometric model to the iris to refine its coordinates. We display a thin bezel of light at the top edge of the screen for constant illumination. A confidence metric calculates the probability of successful iris detection. Calibration and linear gaze mapping between the estimated iris centroid and physical pixels on the screen results in low latency, real-time iris tracking. A formal study confirmed that our system’s accuracy is similar to eye trackers in commercial VR headsets in the central part of the headset’s field-of-view. In a VR game, gaze-driven user completion time was as fast as with head-tracked interaction, without the need for consecutive head motions. In a VR panorama viewer, users could successfully switch between panoramas using gaze. Presented on: ACM Transactions on Applied Perception
