DevPlay Research Report
A lightweight, evidence-linked account of the research system and its current limits.
Research briefing · September 2026
From reliable video evidence to development intelligence.
DevPlay is establishing the technical chain required to preserve player identity, understand football actions, and measure development responsibly over time.
Objective
Establish persistent player identity across a full football session. The immediate blocker is identity recovery after track fragmentation, occlusion and long temporal gaps.
Technical architecture
Identity & Physical Continuity
Recording integrity, tracking, identity recovery, physical metrics, and continuity over time.
Football Semantics
Events, passes, actions, possession, pressure, and football context can progress on anonymous player tracks before Layer 1 resolves identity.
Development Intelligence
Individual progress, trajectory, longitudinal insight, and decision support grounded in observed football evidence.
Methodology
Every experiment separates tested conditions, untested boundaries, direct observations, inference, and remaining hypotheses. Strategic decisions enter the research record only after Admin review.
Current findings
Layer 01 — Identity & Physical Continuity
50%Long-gap identity recovery. Unresolved: Reliable re-identification after extended occlusion
Layer 02 — Football Semantics
10%Ball detection and player-to-ball association. Unresolved: Reliable ball tracking and attribution to anonymous player tracks
Layer 03 — Development Intelligence
0%Longitudinal player history architecture. Unresolved: Cross-session identity and comparable metrics are not established
Unresolved questions
- Can one player remain one identity across a full session?
- Can anonymous player tracks become reliable football understanding?
- Can evidence become a trustworthy picture of individual development?
