Intervention Design at the Intersection of Accessibility and Digital Wellbeing

Web browser extensions are used by individuals to customize and improve websites via targeted interventions. These browser extensions are developed in two similar research areas--accessibility and digital wellbeing--but their overlap and similarities have not yet been discussed. This paper integrates recent accessibility guidelines and digital wellbeing design aspects to propose ten web browser interventions which bridge cognitive/learning disabilities and attentional needs for digital wellbeing. The interventions are designed for two use cases--single-page web apps and web form submissions--and are classified and analyzed according to their interaction strategy (additive/subtractive/redesign) and their use of adaptive functionality. This paper contributes a new set of intervention designs which are theoretically grounded in both digital wellbeing and accessibility, opening new pathways for digital wellbeing research to address inclusive design and web experiences that support a wider range of users and needs.
