Meet Dean Holden, a music-loving, vinyl-collecting family man who has also made significant contributions to web accessibility in his decades of experience in the corporate world.

In this post, we cover updates we've made to our own site in order to better satisfy the requirements of the Web Content accessibility Guidelines (WCAG) 2.1 Level AAA.

An element's name, or accessible name, is how it's identified. An accessible description provides additional information, about the element, that complements the accessible name.

In this post we explore assigning accessible names and descriptions using HTML and WAI-ARIA.

In our second post about creating accessible experiences within Extended Reality (XR), we highlight some key considerations for designing accessible augmented reality (AR) experiences with our AR TetraLogical principles cube.

A pointer gesture is an action a person performs using their finger, mouse, or an assistive technology like a head pointer or eye gaze system to operate a functional control. Some pointer gestures can be difficult or even impossible for certain people to perform, so an accessible alternative may be required.

This post introduces the different forms of pointer gestures and covers how and when to provide alternatives for people who can't perform them.

Meet Graeme Coleman. Single-handedly propping up the Scottish arm of TetraLogical, Graeme has been tirelessly working towards better accessibility with us since the very beginning.

As part of our ongoing effort to meet the Web Content accessibility Guidelines (WCAG) 2.1 and 2.2 Level AAA, we've created British Sign Language (BSL) versions of our video and created BSL playlists in our TetraLogical YouTube channel.

In this post we explore our process for adding BSL to videos and share some tips.

In this post we explore what WAI-ARIA is, and how it can enhance the user experience for people using screen readers.

Meet Joe Lamyman, an accessibility specialist at TetraLogical and lover of all things interactive media.

In this series, Inclusive Extended Reality (XR), we will be delving into ways to design accessible experiences when interacting with 3D objects, augmented reality, and virtual reality.

In our first post about creating accessible experiences within Extended Reality (XR), we highlight some key considerations for designing 3D model viewers by introducing our 3D TetraLogical principles cube.
