Part I — The Case for a Track-Every-Body System
I. Introduction and Motivation
Retailers operate on razor-thin margins, and inventory losses — often referred to as shrink — represent one of the largest unseen drains on profitability. Shrink encompasses the disappearance of products that never result in a legitimate sale — whether from external theft, internal misplacement, damage, spoilage, or administrative errors. Industry-wide, shrink has remained a significant problem: the National Retail Federation’s latest surveys show that retail shrink accounted for over $112 billion in annual losses, representing roughly 1.6 % of total retail sales in 2022 and rising compared to previous years. National Retail Federation
While large formats such as warehouse clubs have traditionally enjoyed lower shrink rates — estimations suggest a chain like Costco may experience shrink as low as 0.11 – 0.12 % of sales, far below historical averages — losses in the broader industry are substantial and persistent. The Maine Criminal Defense Group In grocery retail specifically, shrink often reaches 2½ – 3 % of total revenue, with perishable departments like produce and dairy disproportionately affected due to spoilage and unrecorded losses. Markt POS These levels imply millions of dollars lost annually for a single large store, even before we consider the broader economic escalation of theft incidents in recent years.
Compounding the problem, organized retail crime and opportunistic shoplifting are increasing, with stores reporting large year-over-year growth in incidents and dollar losses. As per another article by the National Retail Federation, under these conditions, traditional loss prevention — security guards, cameras at exits, or random manual inventory counts — struggles to keep pace. What’s needed is not simply another sensor but a comprehensive system that sees the store holistically and continuously in both space and time.
II. Conceptual Overview of the Track-Every-Body System
The Track-Every-Body (TEB) system is proposed as a store-wide, camera-based, real-time tracking and continuity framework that binds together people, parties, carts, items, workers, pallets, and inventory movement into a persistent operational model. It is designed to replace periodic audits, reduce loss, enhance checkout efficiency, and create a live digital twin of what is happening throughout the retail environment.
At its core, TEB unifies two fundamental capabilities:
Continuity-based observation: Instead of treating each camera frame independently, TEB builds persistent identities and histories for every tracked entity, dramatically reducing ambiguity and misattribution across occlusions and movement.
Semantic event tracking: By recognizing and timestamping discrete interactions (e.g., picking an item from a shelf, placing an item into a cart, worker restocking), TEB constructs an accurate event ledger that reflects true store dynamics.
Together, these allow the store to know who took what and where, not just at the point of sale, but across the entire shopping process.
Figure 1: Core entities tracked by the Track-Every-Body (TEB) system and their persistent relationships inside the store.
III. Party Inference and Shopper Behavior
A key insight behind TEB is that shopping is not always a solo activity. Retailers typically judge shrink and theft on a per-customer basis, but real behavior involves groups (families, couples, friends) whose members join and separate fluidly over time. TEB introduces a party model that infers groupings using three behavioral cues:
Proximity: Who stays close and moves together.
Speech activity: Conversational patterns and turn-taking.
Body orientation and visual attention: Who looks at whom and signals engagement.
Figure 3: Multi-signal fusion engine combining proximity, speech, and body orientation to infer parties and manage group splits and merges.
By integrating these cues into a probabilistic graph model with edge weights that strengthen or weaken over time,
Figure 2: Party and identity continuity maintained over time using memory and hysteresis rather than frame-by-frame detection.
TEB maintains party associations even if individuals separate temporarily or enter the store at different times. This ensures that inventory movements and item interactions are attributed to the correct relationship context, reducing false positives in loss prevention and building a more accurate picture of customer intent.
IV. Cart and Item Interaction Tracking
In conventional retail systems, carts are anonymous objects; items are scanned manually at checkout, leading to gaps in attribution and opportunities for loss. TEB reimagines carts as entity objects whose history is as significant as that of people and items.
Figure 4: Item movement tracked as discrete events from shelf to exit, replacing traditional checkout scanning with continuous attribution.
TEB treats carts as passive tracked objects that are continuously associated with a person or party via:
Handle contact
Close and sustained proximity
Shared item interaction events (e.g., placing objects into the cart)
This evolving cart-party linkage — maintained via persistent memory — ensures that any item placed into a cart is reliably attributed to the right party, even if someone leaves the immediate vicinity of the cart. By recognizing and logging events such as SHELF_PICK, CART_PLACE, and CART_REMOVE, TEB constructs an audit trail that can be used to present running totals to customers and generate accurate exit totals, eliminating the traditional manual scanning workflow.
V. Membership Anchoring and Payment Flow
Rather than relying on cashiers, TEB uses membership as an anchor point: when a customer scans their membership at entrance, the system creates a party anchor to which item activity can be attributed. This approach preserves customer autonomy and avoids introducing potentially unsafe or intrusive payment hardware into public areas.
Figure 5: Inventory maintained as a live ledger updated by pallet arrivals, worker actions, purchases, and returns.
At the end of the shopping session, a brief confirmation step — either in an app or on a display — allows the charges to be finalized against the customer’s card-type payment method that would be added (by the user) onto the app. Cash and check exceptions are handled by dedicated staff lanes, so the bulk of customers benefit from a streamlined, electronic checkout without being forced into high-risk hardware interfaces.
VI. Continuous Inventory via Worker Observation
One of the most labor-intensive aspects of retail operations today is inventory counting — periodic, manual reviews that frequently disrupt store activity and nonetheless result in inaccuracies. In contrast, TEB turns workers into implicit sensors. Every movement a restocking associate makes — taking cases off pallets, shelving items, relocating stock — is visually observed and logged.
The system combines this with known pallet counts (which arrive with SKU and unit metadata) to continuously maintain SKU tallies and accurate location assignments. As a result, inventory becomes a live data stream, not a periodic snapshot, eliminating inventory counting days and enabling precise replenishment planning.
VII. Loss Prevention and Internal Trust Modeling
With party inference, persistent cart linkage, and item event logging, TEB creates an unprecedented evidential basis for loss prevention. Instead of guessing intention from obfuscated camera angles or exit alarms, loss prevention teams can receive evidence packets containing:
Detailed timelines of events
Associated parties and member anchors
Video snippets synchronized to suspicious actions
Confidence scores
These evidence packets support human review and adjudication rather than automated punitive action — reducing false positives and improving the overall experience for legitimate customers.
Over time, TEB also builds internal trust scores for memberships based on historical patterns, discrepancy rates, and dispute resolution histories. This score is internal and opaque, used only to modulate audit frequency and exit friction, not as a public credit metric, preserving fairness and governance.
Part II — The Evolution to Autonomous Fulfillment
I. From Tracking to Automation: A Natural Progression
Figure 6: Clear separation between Stage I human retail and Stage II autonomous fulfillment for safety, liability, and regulatory control.
Once a store has achieved robust continuity tracking — understanding where every person, party, cart, item, and pallet is at all times — the natural evolution is to shift from observing to acting. Stage II builds upon the foundation established in TEB, extending the store ecosystem into a space where autonomous agents (robots) perform the physical tasks of picking and fulfillment in zones not shared with human shoppers.
II. Autonomous Fulfillment Zones and Safety Boundaries
In Stage II, the traditional retail floor is converted — either physically or logically — into a robot-only fulfillment zone. This controlled environment allows the introduction of kinetic agents:
Self-driving, self-charging carts
Humanoid picking robots
AI-powered forklifts
Autonomous delivery handlers
To ensure safety and operational clarity, human shoppers are excluded from this zone. Instead, they interact with the store remotely, either through mobile apps or immersive VR shopping interfaces. This separation reduces collision risk and enables higher payload, speed, and complexity in robotic movements.
III. Autonomous Cart Ecosystem
Unlike the passive carts of Stage I, autonomous carts in Stage II navigate the store without manual pushing, routinely docking to ground rail charging stations and routing themselves to task assignments. Because human safety constraints are relaxed in dedicated zones, these carts can use higher-power charging infrastructure and advanced navigation algorithms, enabling efficient start-to-finish fulfillment.
Cart tasks include:
Driving to a picking robot’s station
Receiving items
Routing to staging or delivery handoff points
Returning to charge autonomously
These agents act as mobile fulfillment bins, orchestrated by the same event ledger system that was developed in Stage I.
IV. Humanoid Picking Robots and AI Forklifts
In Stage II, humanoid robots act not as decision makers, but as agents of execution. They receive precise pick lists — derived from TEB’s accurate inventory state — and follow instructions to:
Walk to a shelf coordinate
Select the correct item
Place it into the autonomous cart
Confirm placement via vision/pose checks
Because the cognitive work (what to pick) is done upstream in the inventory and event system, humanoids can be simpler, more reliable, and easily replaceable.
Similarly, AI forklifts become the backbone of bulk stock management: intake, put-away, replenishment staging, and removal of waste or damaged goods. TEB’s live inventory model provides the signals that generate forklift missions without human intervention, improving safety and throughput.
V. Robot-to-Robot Commerce and Settlement
A particularly powerful aspect of Stage II is the shift to robot-to-robot commerce: settlement occurs at the precise moment custody of the product transfers from a picking agent into a delivery agent’s cart.
Figure 7: Custody transfer between autonomous agents enables instant, ledger-based settlement without checkout or fraud windows.
Because every movement is tracked and the event ledger is authoritative, payment settlement becomes instantaneous and machine-driven — eliminating the need for human scanning, interaction, or manual checkout.
This opens possibilities for automated delivery partners (e.g., Instacart bots) to seamlessly take custody and complete transactions, with retailers being compensated immediately at the fulfillment endpoint.
VI. Remote and VR Shopping Interfaces
To preserve the experiential element of shopping — browsing, discovery, serendipity — Stage II supports remote interactions. Customers may use an app or VR interface to virtually walk the aisles, inspecting product placements and details, without physically entering the robot zone.
This approach eliminates safety concerns while offering a modern, engaging experience that aligns with digital expectations. It also ensures that human preference data enriches the fulfillment system — informing predictive stocking, recommendations, and layout design.
VII. Governance, Policy, and Ethical Considerations
Both stages require thoughtful governance around:
Privacy and retention policies
Evidence-based LP escalation
Appeals and dispute mechanisms
Fairness in internal trust scoring
Human oversight of autonomous zones
TEB is designed to support transparency and auditability, not opacity. Decisions are logged, explainable, and reviewable by humans — ensuring ethical application and customer trust.
VIII. Conclusion: A Roadmap to Smarter Retail
What begins as a comprehensive tracking system to mitigate shrink and streamline checkout naturally evolves into a robotic fulfillment ecosystem that reimagines the boundaries of retail. The Track-Every-Body system isn’t a futuristic add-on; it’s a practical foundation that addresses real financial losses today and unlocks powerful automation for tomorrow.
By addressing the root causes of shrink through continuous tracking, event attribution, and evidence-driven loss prevention, retailers can see immediate ROI. With that foundation in place, the transition to an autonomous fulfillment environment — safe, efficient, and scalable — becomes not just possible, but inevitable.
