Cognitive Dimensions

During the design and development of a technological artifact or when such artifact is already in the hands of users, an inspection method can help researchers and practitioners deal with not only usability issues, but also provide a common language to evaluate different design alternatives. The Cognitive Dimensions of Notations framework (CDNf) is a methodological resource designed to identify and discuss cognitive loads imposed by notations. In this six hour short course, we aim to talk about our experience with CDNf alone and combined with other HCI methods and to explore CDNf in practice with hands on activities to show participants how it can be a useful resource.

The main objective is to develop efficient vehicle with affordable price and by using less effort to propel the vehicle. Style and manufacture a chair trike attachment for higher accessibility and performance of a chair user. This trike is incredibly with efficiency designed and might be proven as a stronger replacement for the autochthonal models employed by the incapacitated keeping in mind the factors like safety, value and performance. Trike for the handicap folks to be propelled by the novel link mechanism hooked up to the steering column changing into cranking, victimization the advantage of leverage, with correct balance and distribution of mass and centre of gravity to crank the wheel shaft for dynamical. As he will use each the hands on the steering, higher management of the vehicle is ensured. The user will go quicker and farther (in out of doors use). Levers area unit ergonomically higher for the user (less body stress induced by propulsion forces then for push rim)

Cognitive Dimensions

Although the Discrete Event System specification (DEVS) has over recent decades provided systems engineers with a scalable approach to modeling and simulation, the formalism has seen little uptake in many other disciplines where it could be equally useful. Our observations of end-user programmers confronted with DEVS theory or software suggest that learning barriers are largely responsible for this lack of utilization. To address these barriers, we apply ideas from human–computer interaction to the design of visual interfaces intended to promote their users’ effective knowledge of essential DEVS concepts. The first step is to propose a set of names that make these concepts easier to learn. We then design and provide rationale for visual interfaces for interacting with various elements of DEVS models and simulation runs. Both the names and interface designs are evaluated using the Cognitive Dimensions of Notations framework, which emphasizes trade-offs between 14 aspects of information artifacts. As a whole, this work illustrates a generally applicable design process for the development of interactive formalism-based simulation environments that are learnable and usable to those who are not experts in simulation formalisms.

Cockpit Design

A study was performed to derive an automation and avionics integration design concept for the NUH-60 Systems Testbed for Avionics Research (STAR) aircraft. The STAR, a one-of-a-kind reconfiguration of the UH-60 Black Hawk helicopter, is being developed by the U.S. Army Avionics Research and Development Activity to provide a flight demonstrator and research vehicle for state-of-the-art cockpit technology. The work was directed toward determining cockpit design preferences associated with single-pilot performance of the Army scout and utility missions. Emphasis was placed on high workload phases of the missions during which eyes-out-of-the-cockpit and hands-on-controls performance capabilities would be most crucial. A number of cockpit-based design alternatives in the areas of communication, navigation, aircraft survivability equipment (ASE) operations, subsystem status monitoring, and aircraft performance computation and prediction were systematically derived and proposed.

Training Delivery

Many initiatives have addressed the global need to upskill biologists in bioinformatics tools and techniques. Australia is not unique in its requirement for such training, but due to its large size and relatively small and geographically dispersed population, Australia faces specific challenges. A combined training approach was implemented by the authors to overcome these challenges. The “hybrid” method combines guidance from experienced trainers with the benefits of both webinar-style delivery and concurrent face-to-face hands-on practical exercises in classrooms. Since 2017, the hybrid method has been used to conduct 9 hands-on bioinformatics training sessions at international scale in which over 800 researchers have been trained in diverse topics on a range of software platforms. The method has become a key tool to ensure scalable and more equitable delivery of short-course bioinformatics training across Australia and can be easily adapted to other locations, topics, or settings.
