User Behavior Adaptive AR Guidance for Wayfinding and Tasks Completion

Augmented reality (AR) is widely used to guide users when performing complex tasks, for example, in education or industry. Sometimes, these tasks are a succession of subtasks, possibly distant from each other. This can happen, for instance, in inspection operations, where AR devices can give instructions about subtasks to perform in several rooms. In this case, AR guidance is both needed to indicate where to head to perform the subtasks and to instruct the user about how to perform these subtasks. In this paper, we propose an approach based on user activity detection. An AR device displays the guidance for wayfinding when current user activity suggests it is needed. We designed the first prototype on a head-mounted display using a neural network for user activity detection and compared it with two other guidance temporality strategies, in terms of efficiency and user preferences. Our results show that the most efficient guidance temporality depends on user familiarity with the AR display. While our proposed guidance has not proven to be more efficient than the other two, our experiment hints toward several improvements of our prototype, which is a first step in the direction of efficient guidance for both wayfinding and complex task completion.

Introduction to Intelligent User Interfaces (IUIs)

This chapter is intended to provide an overview of the Intelligent User Interfaces subject. The outline includes the basic concepts and terminology, a review of current technologies and recent developments in the field, common architectures used for the design of IUI systems, and finally the IUI applications. Intelligent user interfaces (IUIs) are attempting to address human-computer connection issues by offering innovative communication approaches and by listening to the user. Virtual reality is also an emerging IUI area that can be the popular interface of the future by integrating the technology into the environment so that at the same time it can be more real and invisible. The ultimate computer interface is more like interacting with the computer in a dialog, an interactive environment of virtual reality in which you can communicate. This chapter also explores a methodology for the design of situation-aware frameworks for the user interface that utilizes user and context inputs to provide details customized to the activities of the user in particular circumstances. In order to comply to the new situation, the user interface will reconfigure itself automatically. Adjusting the user interface to the actual situation and providing a reusable list of tasks in a given situation decreases operator memory loads. The challenge of pulling together the details needed by situation-aware decision support systems in a way that minimizes cognitive workload is not addressed by current user interface design.

Charter Authenticated Anti-Theft Secure Motor System

The prominent mode of transportation being used by the public is roadways. Increased usage of roadways may lead to many accidents and thefts. The major reason is violation of rules drafted for driving and causing accidents mainly by the youngsters who does not have a proper knowledge and license. So this proposed system has some restrictions to follow the rules drafted for driving and for higher safe and security, the License is scanned by means of NFC tag. When it is read by the NFC reader, Node MCU provides two-way authentication facility by sending an SMS to both the owner for authorization and the authorized current user would be able to control our vehicle by means of switching on and off the engine. The owner authorizes the user for a particular time period by using real time clock module. Without authorizing the license, the engine cannot have turned on. So, in this case license become mandatory to drive the vehicle. The features of the application to control the vehicle through the attached device. This will help a person to control the vehicle from anywhere. If a robber tries to snip the vehicle, immediately the Micro-Electromechanical System sends a signal to the controller and will be notified by a text message. Any violation to unlock the vehicle, emergency alert will send to owner as well as the current user and alarm blows out to seek the attention. This device can setup both in two-wheeler and four-wheeler.

The Association between Depressive Mood and Conventional and Electronic Cigarette Dual Use in Adult Male: Using Korea National Health and Nutrition Examination Survey

Background: Depression is well known to be associated with nicotine dependence. Recent studies reported higher depressive score is associated with use of e-cigarettes, however, little study showed the association between depression and both cigarette dual use. The purpose of this study is to evaluate the association between depressive mood and conventional and electronic cigarette dual use among male adults.Methods: Data of 7,459 male adults from sixth and seventh Korea National Health and Nutrition Examination Survey (2014, 2016, and 2018) were analyzed. Patient Health Questionnaire-9 (PHQ-9), current smoking status, and electronic cigarette use status were evaluated among them. The association between depressive mood and electronic cigarette use were assessed after adjusting age, education, income, alcohol, and perceived stress level using multivariate logistic regression analysis. The risk of depressive mood for dual users were also assessed. STATA 11.0 (Stata Corp., College Station, TX, USA) were used.Results: The both group of e-cigarette current user or ex-user reported higher depressive scores (PHQ-9) than never-user group (never-user group 1.94±0.05, ex-user group 2.57±0.13, current user group 2.69±0.22, P<0.001). In the multivariate logistic analysis, 1 point increase of depressive mood score was associated with risk of e-cigarette current use (odds ratio [OR], 1.062; 95% confidence interval [CI], 1.021-1.105) among total male adult group or conventional & electronic tobacco dual use (OR, 1.054; 95% CI, 1.012-1.098) among current smokers.Conclusions: Depressive scores were positively associated with e-cigarette use or both conventional or e-cigarette use. It is necessary to evaluate and treat smoker’s depressive mood for tobacco control.

37 Sibs: an R toolkit for computation of relatedness measures using large pedigrees

Without appropriate relationships present in a given population, identifying dominance effects in the expression of desirable traits is challenging. Including non-additive effects is desirable to increase accuracy of breeding values. There is no current user-friendly tool package to investigate genetic relatedness in large pedigrees. The objective was to develop and implement efficient algorithms in R to calculate and visualize measures of relatedness (e.g., sibling and family structure, numerator relationship matrices) for large pedigrees. Comparisons to current R packages (Table 1) are also made. Functions to assign animals to families, summary of sibling counts, calculation of numerator relationship matrix (NRM), and NRM summary by groups were created, providing a comprehensive toolkit (Sibs package) not found in other packages. Pedigrees of various sizes (n = 20, 4,035, 120,000 and 132,833) were used to test functionality and compare to current packages. All runs were conducted on a Windows-based computer with an 8 GB RAM, 2.5 GHz Intel Core i7 processor. Other packages had no significant difference in runtime when constructing the NRM for small pedigrees (n = 20) compared to Sibs (0 to 0.05 s difference). However, packages such as ggroups, AGHmatrix, and pedigree were 10 to 15 min slower than Sibs for a 4,035-individual pedigree. Packages nadiv and pedigreemm competed with Sibs (0.30 to 60 s slower than Sibs), but no package besides Sibs was able to complete the 132,833-individual pedigree due to memory allocation issues in R. The nadiv package was closest with a pedigree of 120,000 individuals, but took 37 min to complete (13 min slower than Sibs). This package also provides easier input of pedigrees and is more encompassing of such relatedness measures than other packages (Table 1). Furthermore, it can provide an option to utilize other packages such as GCA for connectedness calculations when using large pedigrees.

Applying Importance-Performance Analysis (IPA) to Interpret the Results of the User Experience Questionnaire (UEQ)

In recent years, user experience questionnaires have established themselves to measure various aspects of User Experience (UX). In addition to these questionnaires, an evaluation tool is usually offered so that the results of a study can be evaluated in the light of the questionnaire. As a rule, the evaluation consists of preparing the data and comparing it with a benchmark. Often this interpretation of the data is not sufficient as it only evaluates the current User Experience. However, it is desirable to determine exactly where there is a need for action. The User Experience Questionnaire (UEQ) is a common and valid questionnaire with an evaluation tool to measure and analyse the User Experience for a product or service. In our article we present an approach that evaluates the results from the User Experience Questionnaire using the importance-performance analysis (IPA). The aim is to create another possibility to interpret the results of the UEQ and to derive recommendations for action from them. In a study with 467 participants, we validated the approach presented with YouTube, WhatsApp, and Facebook. The results show that the IPA provides additional insights from which further recommendations for action can be derived.
