User interface controls

For the safety case, evidencing both evaluations is particularly convincing especially when carried out by the manufacturers. The formative evaluation helps to shape the requirements, take account of control options, iteratively refine the solution and build confidence in the design strategy. The summative evaluation allows specific user interface controls to be validated both in terms of their presence and effectiveness.

The set of user interface components supplied with MATLAB allows the user to design GUIs that match those used in sophisticated software packages. Such components are graphics objects with handles and properties. They come in two classes user interface controls (uicontrols) and user interface menus (uimenus). The uicontrols and uimenus can be combined with other graphics objects... 

Non-speech voice input as a user interface control modality holds the potential for offering effective input modality for individuals with physical or situation-induced motor impairment, but this space has been relatively unexplored. Through studying the adoptability of such techniques by novice users, we hope to gain a better understanding of whether such systems are indeed viable, and what their ease of use and learnability are. By combining results from prior studies that compare these systems to common input devices (e.g. VJ and the mouse in [4]), we can also place these novel input methods on the map of other existing input devices. 

The control of the airborne sound location system, the coupling monitor and the real-time evaluation of all signals, including the echo indications from the ultrasonic instrument, is carried out on two additional boards in the PC. The graphic user interface (under Windows 95), including online help, enables an easy operation of the system. The evaluation program links all echo indications in real time with the probe position and displays them in a graphic repre-... 

The user interface and the simplicity of usage are important issues. Likewise, stabilized and qualified control for some of the control loops must he as simple as possible. 

Future trends for the evolution of EMCS are likely to involve improvements in user interface, easier access, better controls, and advances m integration, namely including the following ... 

The software is written in the C language on an Atari ST microcomputer (1) and utilizes a GEM graphics user interface which features mouse control, windows, pulldown menus, and pop up alert and data entry boxes. The system could be ported to the IBM PC under the GEM operating system if the need were to arise.

Any model railroad enthusiast will recognize this as a neat kit of parts with which you could build a lot of different projects—many more potential products than the number of components in the box. Note the ease of modifying the first version to realize the second. It s not difficult to imagine such a kit in hardware nor to visualize it in software. The Motor could be a software component controlling a hardware motor the Buttons, Meter, and Selector could be user-interface widgets and the other components could be objects not directly visible to the user. 

The principle is not limited to single classes but rather can span multiple abstract classes that collaborate and must be jointly extended before use. Many class libraries provide user-interface frameworks (such as Smalltalk s Model-View-Controller). You make a user interface (either manually or with a visual builder tool) by inheriting from the framework classes and plugging specializing methods in to your subclasses. 

The Model-View-Controller (MVC) architecture (or some variant) is commonly used in the design of user interfaces. A user-interface element is associated with a single model—the object that acts as the source of the information presented, and the recipient of user requests. Each element is designed as a pair of a view, which deals with the presentation aspects of information from the model and a controller, which is responsible for interpreting user inputs and gestures for the view and the model. The view and controller roles are combined into a single object in some variants. 

User interface planners interface to the system to manage input and control data, define model control parameters and scenarios, start the optimization and to analyze optimization results and indicators in graphs and dynamic reports. 

Database central point for all input and control data like optimization results with 50 tables, related queries and user interface forms. 

User interface objective is to provide direct access to all data and results and to support interactive definition of model control data as well as analysis of key indicators. Specifically, the model control parameters can be set interactively. The most important parameters shown on the left side of the screen header are ...

Overall, most of the requirements for a process spectrometer/analyzer are straightforward to implement, but they do require attention at the design level. Another important area, which is FTIR specific, is the user interface and the need to provide for industry standard data communications. Standard software packages do exist for process instrumentation. For prototype development, and even for the front-end interface in a stand-alone mode of operation, software products, such as National Instraments Lab View and the Mathworks MatLab, are also important instrumentation development tools. Note that National Instruments also provides important computer-based electronics and hardware that meet most of the computer interfacing, and system control and communications needs for modem instrumentation. For practical installations, a product known... 

Other researchers have improved on both knowledge base and sensors, often using different programming tools, but with much the same results. Most of these systems have not been transitioned to commercial application because they were developed by researchers who had no interest in the development of user interfaces and the continued support that is necessary for a commercial software package. As a consequence of the success of these experimental systems, however, the developers of commercial supervisory control packages are moving to incorporate support for expert system logic into their software [24,25],...
