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.

01

Objective

Establish persistent player identity across a full football session. The immediate blocker is identity recovery after track fragmentation, occlusion and long temporal gaps.

02

Technical architecture

Layer 01

Identity & Physical Continuity

Recording integrity, tracking, identity recovery, physical metrics, and continuity over time.

Layer 02

Football Semantics

Events, passes, actions, possession, pressure, and football context can progress on anonymous player tracks before Layer 1 resolves identity.

Layer 03

Development Intelligence

Individual progress, trajectory, longitudinal insight, and decision support grounded in observed football evidence.

03

Methodology

Every experiment separates tested conditions, untested boundaries, direct observations, inference, and remaining hypotheses. Strategic decisions enter the research record only after Admin review.

04

Current findings

Layer 01Identity & Physical Continuity

50%

Long-gap identity recovery. Unresolved: Reliable re-identification after extended occlusion

Layer 02Football Semantics

10%

Ball detection and player-to-ball association. Unresolved: Reliable ball tracking and attribution to anonymous player tracks

Layer 03Development Intelligence

0%

Longitudinal player history architecture. Unresolved: Cross-session identity and comparable metrics are not established

05

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?
