Abstract

Mobile services increasingly mediate access to essential transactions, yet compliance with accessibility standards alone does not guarantee efficient interaction for older adults and people with disabilities. This article develops a software engineering framework for mobile user interface patterns that links accessibility requirements with measurable interaction cost, implementation choices, and release governance. The framework formalizes focus-step budgeting for assistive-technology navigation and specifies how budgets can be enforced across design systems, accessibility testing, CI/CD gating, and regression monitoring. The analysis synthesizes empirical findings in software engineering, large-scale accessibility evidence, platform guidance, human-centred design standards, and recent work on mobile interaction barriers. A formative evaluation indicates that pattern-aligned interface design reduces navigation burden and improves usability outcomes, supporting focus-step budgeting as an engineering metric rather than a purely descriptive accessibility notion.
