What is Lord of User Interface?
At Lordicon, we believe that moving towards clearer communication is at the very heart of every icon, designed to perpetually guide us forwards.
Ultimately, we aim to preserve visual consistency by harnessing rhythm, spacing, and legibility in the pursuit of harmony. We do this using basic geometry, aligned on a proportionately adaptable grid.
Animation serves to heighten that core mission, adding a whole new dimension to the way we communicate. Animated icons bring static images to life, effectively expressing everything from meaning to function. They delight by doing more with less.

A graphical user interface (GUI) is a type of user interface through which users interact with electronic devices via visual indicator representations.
The graphical user interface, developed in the late 1970s by the Xerox Palo Alto research laboratory and deployed commercially in Apple’s Macintosh and Microsoft’s Windows operating systems, was designed as a response to the problem of inefficient usability in early, text-based command-line interfaces for the average user.
Graphical user interfaces would become the standard of user-centered design in software application programming, providing users the capability to intuitively operate computers and other electronic devices through the direct manipulation of graphical icons such as buttons, scroll bars, windows, tabs, menus, cursors, and the mouse pointing device. Many modern graphical user interfaces feature touchscreen and voice-command interaction capabilities.
Graphical user interface design principles conform to the model–view–controller software pattern, which separates internal representations of information from the manner in which information is presented to the user, resulting in a platform where users are shown which functions are possible rather than requiring the input of command codes. Users interact with information by manipulating visual widgets, which are designed to respond in accordance with the type of data they hold and support the actions necessary to complete the user’s task.
The appearance, or “skin,” of an operating system or application software may be redesigned at will due to the nature of graphical user interfaces being independent from application functions. Applications typically implement their own unique graphical user interface display elements in addition to graphical user interface elements already present on the existing operating system. A typical graphical user interface also includes standard formats for representing graphics and text, making it possible to share data between applications running under common graphical user interface design software.
Graphical user interface testing refers to the systematic process of generating test cases in order to evaluate the functionality of the system and its design elements. Graphical user interface testing tools, which are either manual or automated and typically implemented by third-party operators, are available under a variety of licenses and are supported by a variety of platforms. Popular examples include: Tricentis Tosca, Squish GUI Tester, Unified Functional Testing (UFT), Maveryx, Appium, and eggPlant Functional.
Maintaining comparability of scores from different forms of a test (and/or from different test administrations) has been a major technical challenge for psychometricians. Today with a major focus of state testing programs on the assessment of growth, the challenge of maintaining comparability of scores has become even more important. Over the years, several IRT based scaling/equating methods have been developed to provide solutions (e.g., Hambleton, Swaminathan, & Rogers, 1991; Kolen & Brennan, 2004; Lord, 1980).
While equating methods research has flourished because of the need for technically sound designs and analyses, software development has been limited. The major testing companies of course have the software they need for scaling and equating but software available for researchers and graduate students is very limited. And, the few computer programs for test scaling and equating that have been developed for wide use, do not always include features of special interest to researchers. For example, available software cannot handle all the popular IRT models being applied to test data, and cannot handle some of the popular equating designs. Thus, a demand for a computer program that is more generalized and powerful for various uses in research and test development has grown in the field, and as a result, a Window application, called IRTEQ, was developed to address that need.
