Autonomous Android Accessibility Agent

EyesAI:
Eyes for the phone

A Kotlin and Jetpack Compose Android app with a FastAPI backend that controls the device end-to-end through an AccessibilityService — a Planner → Executor → Verifier agent at 87% task completion, backed by on-device vision and TTS-first feedback.

Academic major project
No public repository or live deployment.

CORE CAPABILITIES

Autonomous Agent

Planner → Executor → Verifier owned by a Controller, reaching 87% task completion.

Accessibility Tree Control

A perception pass over the accessibility tree drives open_app, tap_element, tap_element_input_text_and_enter and done.

Dual-Pipeline Vision

On-device TFLite with COCO labels alongside an ML Kit labeler — 88.2% accuracy at 151ms latency.

Live Narration

Gemini Live scene narration over a throttled 1-fps frame feed from CameraX.

Multilingual Voice

English, Hindi and Hinglish commands at 94% accuracy — Levenshtein static matching with a Gemini function-calling fallback.

Non-Visual Feedback

TTS and haptics first, with displayLarge 36/44 and bodyLarge 17/24 accessibility typography.

On-Device Interface

Accessibility-first screens; the detection overlay is a debug view of the vision pipeline.

AGENT LOOP

Perception/Planner/Executor/Verifier

A Controller owns the loop: perception reads the accessibility tree, the Planner decides the next action, the Executor performs it on the device, and the Verifier confirms the result before the next step.

ACTION SPACE

open_app

Launch a target application.

tap_element

Tap a node resolved from the accessibility tree.

tap_element_input_text_and_enter

Focus a field, type, and submit.

done

Signal task completion back to the Controller.
