Augmented reality user interface for an atomic force microscope-based nanorobotic system

A real-time augmented reality (AR) user interface for nanoscale interaction and manipulation applications using an atomic force microscope (AFM) is presented. Nanoscale three-dimensional (3-D) topography and force information sensed by an AFM probe are fed back to a user through a simulated AR system. The sample surface is modeled with a B-spline-based geometry model, upon which a collision detection algorithm determines whether and how the spherical AFM tip penetrates the surface. Based on these results, the induced surface deformations are simulated using continuum micro/nanoforce and Maugis-Dugdale elastic contact mechanics models, and 3-D decoupled force feedback information is obtained in real time. The simulated information is then blended in real time with the force measurements of the AFM in an AR human machine interface, comprising a computer graphics environment and a haptic interface. Accuracy, usability, and reliability of the proposed AR user interface is tested by experiments for three tasks: positioning the AFM probe tip close to a surface, just in contact with a surface, or below a surface by elastically indenting. Results of these tests showed the performance of the proposed user interface. This user interface would be critical for many nanorobotic applications in biotechnology, nanodevice prototyping, and nanotechnology education.     

AB-HCI: an interface multi-agent system to support human-centred computing

Currently, new types of information are available to applications. This incoming stream of data can be processed to improve user experience. User experience can be enhanced to present contents to users in a better manner, or to provide software artefacts to improve their interaction with the environment. The wide range of interaction design capabilities offered by this data requires methods and run-time architectures able to cope with the integration of the incoming data from the interaction environment into the applications. Human-centred computing takes into account what the state of user interaction is and how this data can be used to actually make it useful. A multi-agent system architecture is described. This architecture is able to tackle the arrival of context data by means of a set of sensors and interface agents that filter and process the context-of-use data to produce new presentations. The context of use provides information about the user, the platform, the physical environment and the current task the user is performing. These new presentations produced are adapted according to the context-of-use information gathered by applying a mixed-initiative approach to overcome some of the usual flaws found in full-adaptive applications.

Supporting conceptual design with multiple VR based interfaces

Conventional computer aided design (CAD) systems have not provided enough support for conceptual design partly due to the lack of natural and intuitive human-computer interaction. Currently emerging virtual reality (VR) based techniques offer new ways to overcome these obstacles. In this paper, new CAD user interfaces including two-handed operation, haptic interaction, stereoscopic display and auditory feedback are investigated. The contribution of this work is to develop a new direct, natural and intuitive interaction paradigm required to support conceptual design. This paradigm enables designers to take fuller advantage of their visual, auditory and tactile sensorial channels to create, view, touch, hold, manipulate and listen to computer-generated virtual models. This is done more easily and freely in a more realistic three-dimensional (3D) environment through convenient interface device operation. A new conceptual design system called the LUCID system that fully integrates and implements these VR-based innovative interfaces into one design application is presented. As an approach to the next generation of human-computer interfaces for use in the design activity, the LUCID system has shown particular human computer interface benefits to designers during conceptual design based on the outcome from the user evaluation test.

An Object-Oriented Modeling Approach in Materials Processing: Case Study of the Acheson and Carburizing Processes

Numerical results can be conveyed effectively to any one using an object-oriented framework. Therefore, it becomes essential to couple the object-oriented approach with numerical analysis. A simple object-oriented methodology for creating a graphical user interface (GUI) as a framework is presented. This work tries to fill a gap between scientific computer code written in a noninteractive way and interactive programming in materials processing. The GUI interface framework has been created in such a way that at any point of time one need not create a new GUI framework. The user only needs to create the process object and attach it to the framework. Two examples have been presented involving interactive finite volume-based gas carburizing and interactive finite difference-based Acheson process (used for the production of silicon carbide).     

Personalized News Recommendation Based on the Text and Image Integration

The personalized news recommendation has been very popular in the news recommendation field. In most research, the picture information in the news is ignored, but the information conveyed to the users through pictures is more intuitive and more likely to affect the users’ reading interests than the one in the textual form. Therefore, in this paper, a model that combines images and texts in the news is proposed. In this model, the new tags are extracted from the images and texts in the news, and based on these new tags, an adaptive tag (AT) algorithm is proposed. The AT algorithm selects the tags the user is interested in based on the user feedback. In particular, the AT algorithm can predict tags that a user may be interested in with the help of the tag correlation graph without any user feedback. The proposed AT algorithm is verified by experiments. The experimental results verified the AT algorithm regarding three evaluation indexes F1-score (F1), area under curve (AUC) and mean reciprocal rank (MRR). The recommended effect of the proposed algorithm is found to be better than those of the various baseline algorithms on real-world datasets.

BERT for Conversational Question Answering Systems Using Semantic Similarity Estimation

Most of the questions from users lack the context needed to thoroughly understand the problem at hand, thus making the questions impossible to answer. Semantic Similarity Estimation is based on relating user’s questions to the context from previous Conversational Search Systems (CSS) to provide answers without requesting the user's context. It imposes constraints on the time needed to produce an answer for the user. The proposed model enables the use of contextual data associated with previous Conversational Searches (CS). While receiving a question in a new conversational search, the model determines the question that refers to more past CS. The model then infers past contextual data related to the given question and predicts an answer based on the context inferred without engaging in multi-turn interactions or requesting additional data from the user for context. This model shows the ability to use the limited information in user queries for best context inferences based on Closed-Domain-based CS and Bidirectional Encoder Representations from Transformers for textual representations.

BOLJAT: a tool for designing composite bolted joints using three-dimensional finite element analysis

This paper discusses the development of a software tool for design of composite bolted joints, using three-dimensional finite element analysis. The tool allows the user to create the joint geometry through a menu-driven interface and then generate a customised mesh according to the user's needs. Contact parameters are defined automatically, which shields the user from the most difficult part of the process. Boundary conditions, bolt pre-loads, and material properties can also be set. Only a few manual steps are necessary to complete the finite element code generation process. By automating the time-consuming model creation process, the tool facilitates the increased use of three-dimensional finite element analysis in the design of composite bolted joints. A case study is shown to demonstrate the usefulness of the tool.
