![]() With the release of the Red Hat Universal Base Image (UBI), you can now take advantage of the greater reliability, security, and performance of official Red Hat container images where OCI-compliant Linux containers run - whether you’re a customer or not. You couldn’t easily share it with others, even if they were a Red Hat Enterprise Linux customer or partner. Running RHEL container images on RHEL container hosts offers compatibility and portability between environments, not to mention familiarity. This is why we have offered Red Hat Enterprise Linux (RHEL) images since Red Hat Enterprise Linux 7 GA, to offer customers certified and up-to-date enterprise-grade containers. Provide adequate space for the use of assistive devices or personal assistance.Containers offer a lighter-weight version of the Linux operating system’s userland stripped down to the bare essentials, but it’s still an operating system and the quality of a container matters just as much as the host operating system. ![]() ![]() Accommodate variations in hand and grip size. Make reach to all components comfortable for any seated or standing user. Provide a clear line of sight to important elements for any seated or standing user. Principle 7: Size and Space for Approach and UseĪppropriate size and space is provided for approach, reach, manipulation, and use regardless of user's body size, posture, or mobility. Allow user to maintain a neutral body position. The design can be used efficiently and comfortably and with a minimum of fatigue. Discourage unconscious action in tasks that require vigilance. Arrange elements to minimize hazards and errors: most used elements, most accessible hazardous elements eliminated, isolated, or shielded. The design minimizes hazards and the adverse consequences of accidental or unintended actions. Provide compatibility with a variety of techniques or devices used by people with sensory limitations. Differentiate elements in ways that can be described (i.e., make it easy to give instructions or directions). Maximize "legibility" of essential information. Provide adequate contrast between essential information and its surroundings. Use different modes (pictorial, verbal, tactile) for redundant presentation of essential information. The design communicates necessary information effectively to the user, regardless of ambient conditions or the user's sensory abilities. Provide effective prompting and feedback during and after task completion. Arrange information consistent with its importance. Accommodate a wide range of literacy and language skills. Be consistent with user expectations and intuition. Use of the design is easy to understand, regardless of the user's experience, knowledge, language skills, or current concentration level. Facilitate the user's accuracy and precision. ![]() Accommodate right- or left-handed access and use. The design accommodates a wide range of individual preferences and abilities. Provisions for privacy, security, and safety should be equally available to all users. Avoid segregating or stigmatizing any users. Provide the same means of use for all users: identical whenever possible equivalent when not. The design is useful and marketable to people with diverse abilities. Principle 7: Size and Space for Approach and Use.According to the Center for Universal Design in NCSU, the Principles "may be applied to evaluate existing designs, guide the design process and educate both designers and consumers about the characteristics of more usable products and environments." The 7 Principles of Universal Design were developed in 1997 by a working group of architects, product designers, engineers and environmental design researchers, led by the late Ronald Mace in the North Carolina State University.The purpose of the Principles is to guide the design of environments, products and communications. ![]()
