AmicoAI: A Digital Tutor for People with Visual, Cognitive, or Motor Difficulties — Conceptual Architecture and Pilot Study Protocol

This document proposes the conceptual architecture of a personal assistance system (a "digital tutor," project name AmicoAI) based on a smartphone worn on the chest via a dedicated harness, designed for people with visual difficulties associated with cognitive decline, motor disability, or autism spectrum conditions. Unlike most existing assistive systems for people with visual impairment — which assume intact cognition and user-commanded interaction — the proposed system is designed to operate with autonomous initiative, providing proactive mobility assistance and continuous cognitive companionship to users who may not be able to actively request support. The document describes a tiered architecture of assistance levels/profiles, the functional scope chosen for the first public release (deliberately limited to wellness/lifestyle-type functions for regulatory reasons discussed in the text), the distribution model (permissive license with voluntary contribution), and a planned single-subject pilot study protocol in a controlled home environment. The purpose of this deposit is to establish a priority date for the idea and its architecture, ahead of planned development, testing, and interdisciplinary collaborations.
