Joystick controllers are used mainly for modern civil drones. However, joystick controllers are non-intuitive and require two hands to be used simultaneously. Therefore, although single-handed drone controllers using a joystick and hand gestures have been introduced, they have only replaced the right stick of the joystick controller with gyro sensors. While this approach retains interface continuity with conventional joystick controllers, it is not user-centric. Therefore we propose a gestural drone controller based on hand gestures, and compare it experimentally with conventional controllers, including an investigation of the effective differences depending on the user’s joystick experience. We separateparticipants into expert and novice joystick groups to investigate the joystick controller experience effects (e.g., radio-controlled cars, game consoles) for each controller type. The conventional joystick controller is found to be superior to the conventional gestural controller for five out of nine criteria, and superior to the proposed gestural controller for three out of nine criteria. The proposed gestural controller is more natural than the conventional gestural controller. There tends to be an interaction effect of the joystick experience and controller types, considering the naturalness of the controller.

Abstract Summary We present a set of software packages that provide uniform access to diverse biological vocabulary resources that are instrumental for current biocuration efforts and tools. The Unified Biological Dictionaries (UniBioDicts or UBDs) provide a single query-interface for accessing the online API services of leading biological data providers. Given a search string, UBDs return a list of matching term, identifier and metadata units from databases (e.g. UniProt), controlled vocabularies (e.g. PSI-MI) and ontologies (e.g. GO, via BioPortal). This functionality can be connected to input fields (user-interface components) that offer autocomplete lookup for these dictionaries. UBDs create a unified gateway for accessing life science concepts, helping curators find annotation terms across resources (based on descriptive metadata and unambiguous identifiers), and helping data users search and retrieve the right query terms. Availability and implementation The UBDs are available through npm and the code is available in the GitHub organisation UniBioDicts (https://github.com/UniBioDicts) under the Affero GPL license. Supplementary information Supplementary data are available at Bioinformatics online.

Abstract Objective This study examines the validity of optical mark recognition, a novel user interface, and crowdsourced data validation to rapidly digitize and extract data from paper COVID-19 assessment forms at a large medical center. Methods An optical mark recognition/optical character recognition (OMR/OCR) system was developed to identify fields that were selected on 2,814 paper assessment forms, each with 141 fields which were used to assess potential COVID-19 infections. A novel user interface (UI) displayed mirrored forms showing the scanned assessment forms with OMR results superimposed on the left and an editable web form on the right to improve ease of data validation. Crowdsourced participants validated the results of the OMR system. Overall error rate and time taken to validate were calculated. A subset of forms was validated by multiple participants to calculate agreement between participants. Results The OMR/OCR tools correctly extracted data from scanned forms fields with an average accuracy of 70% and median accuracy of 78% when the OMR/OCR results were compared with the results from crowd validation. Scanned forms were crowd-validated at a mean rate of 157 seconds per document and a volume of approximately 108 documents per day. A randomly selected subset of documents was reviewed by multiple participants, producing an interobserver agreement of 97% for documents when narrative-text fields were included and 98% when only Boolean and multiple-choice fields were considered. Conclusion Due to the COVID-19 pandemic, it may be challenging for health care workers wearing personal protective equipment to interact with electronic health records. The combination of OMR/OCR technology, a novel UI, and crowdsourcing data-validation processes allowed for the efficient extraction of a large volume of paper medical documents produced during the COVID-19 pandemic.

<p><strong>Abstract.</strong> The need for car-related navigation and the appearance of the vehicles themselves are much the same age – of course. In the early days, paper maps and personal questioning were solved this problem. Nearly 100 years ago, the first built-in car GPS was released – and this is an innovation that is still an important part of car design. Planning the user interface is a very exciting issue, because only in a few seconds the display needs to provide the user with the right amount of information. In this research our goal was to assess Hungarians driving and built-in GPS using habits and based on this try to suggest the “perfect” interface. A questionnaire was made with 19 or 46 questions and more than 1000 respondents completed it. Because of the high number of questions only selected diagrams are represented. Some answers have also been subjected to different statistical tests.</p>

So far, there are coaches who are less precise in determining the ideal position of the player as it only relies on instinct and the ego of the players so that there is still a coach who has not been able to objectively assess the players.By utilizing the method of Genetic Algorithm as Decision Support System (DSS) in the process of determining the ideal position of a player who uses several criteria (multicriteria) to choose a proper player. DSS is helping coach in making the right decisions and Genetic Algorithm is used as a model for multicriteria weighting in the selection process. This application was built with tools Borland Delphi (7.0) as the user interface design and media processing PostgreSQL as its database.            Based on these results we can conclude that this application expected to assist the coaches in the decision making process and can change the appraisal of which are subjective to more objective, to determine the ideal position for a player, can determine the best position of each position of a number of players and the expected results of the Genetic Algorithm on the system constructed in accordance with the results of manual calculations.

The corporate world today basically relies on presentations of ideas and statistics. In the board room, the presenters are highly conscious of depicting confidence in their presen-tation. This would entail accessibility and mobility to the presenter or media viewer. As the extent of Artificial Intelligence is increasing in all directions, I am utilizing its extreme capabilities to create a software that would help in accessibility and save time and money. This paper describes a software written in Python 3.8 and makes use of Python libraries like OpenCV and PyAutoGUI to receive input from the computer’s Webcam and recognize gestures to control the PowerPoint Presentation and Portable Document For-mat (PDF) files or the Media Control. The user interface is built with the Python library PyQt5. This paper aims are to help people control their Presentations and Portable Document Format (PDF) files, and many other media through their hand gestures, without using a mouse or any other pointing device. The software would not require any other external hardware; hence it would not burn a hole in people’s pockets.

The free exchange of data between many interconnected nodes, in the absence of a central point of control, has been at the heart of the Internet’s architecture since its inception. For its engineering architects “if the Web was to be a universal resource, it had to grow in an unlimited way”, thus “its being ‘out of control’ was very important” (Berners-Lee and Fischetti, 1999). Yet, this simple deign choice has had a serious impact on conventional legal thinking. This paper highlights the importance of online decentralized architecture as the perfect substantiation of the autonomy rational underpinning the right to free speech.In doing so the paper analyses the core principles supporting the Internet’s architecture on their merit to the promote the user’s autonomy and self-realisation through speech. Following the free speech rationale for autonomy, it is observed how some simple engineering decisions for an open decentralised communicatory platform can build a user-centric ecology for speech. To validate this hypothesis two main architectural choices are examined as to the potential they hold for free speech: the principles of Modularity and End-to-End (E2E).The paper concludes that in terms of free speech, law and net architecture should be seen as complementing factors instead of opposite controlling deities. In this respect, Lessig’s mantra that “code is law” is paraphrased to read as “law encoded”, meaning that the law should strive to maintain the core architectural Internet values promoting human rights, and free speech in particular.
