The Invisible Interface: AI and Low-Friction Design for Cognitive Assessment in Older Adults 1: UNIVERSIDAD ICESI, Colombia; 2: Fundacion Valle del Lili, Colombia This paper examines cognitive friction in digital cognitive assessment workflows for older adults, focusing on both the patient experience and the clinical staff administering standardized tests. Grounded in Cognitive Load Theory and classical usability principles, we position AI as cognitive scaffolding that reduces extraneous load in two layers: software development and bedside execution. We propose a practical low-friction design guide for tablet-based assessments, emphasizing explicit affordances, single-path navigation, multisensory feedback, and objective trace capture. Using early field experience from Parkinson’s disease screening brigades in Colombia, we illustrate how automated scoring, voice capture, and reaction-time logging improve operational reliability and data quality without increasing perceived complexity. We conclude that “invisible interfaces” are not only a performance choice but an ethical requirement to expand access and reduce technology-related anxiety in vulnerable populations. | |
