# Agency-Driven Interaction Mode

Agency-driven interaction mode refers to interface, control, and protocol paradigms in which a human user or artificial agent is designed to maintain meaningful initiative, influence, and authorship over computational workflows, information flows, or collaborative environments. It contrasts both with high-automation, agent-driven systems where users become passive subjects, and with entirely manual systems where all control is retained but efficiency and augmentation potential are lost. The agency-driven paradigm—across human–AI collaboration, autonomous agents, and interactive systems—seeks to rigorously model, preserve, and adapt the locus of control and the capacity for users or agents to shape outcomes according to their own goals, preferences, and self-generated norms.

## 1. Foundations and Definitions

Agency in interactive systems is operationalized as the degree to which an entity—human or artificial—exerts causal influence on actions, decisions, or outcomes, framed relative to system automation or external constraint. Several complementary definitions and models have emerged:

- **Agency as Control Input Allocation**: Quantified formally as the norm of human control input $\|u_h\|$ relative to machine input $\|u_a\|$ in the total control law, with an authority allocation parameter $\lambda \in [0,1]$ balancing agency (human) and automation (machine): $J = \int_0^T [ (1-\lambda)R_h(u_h) + \lambda R_a(u_a) + Q(x) ] dt$ [2502.13779].

- **Human Agency in HCI/HAX**: Explicit in Human-Data Interaction as the ongoing capacity to understand, intervene in, and audit both raw data and downstream inferences—formalized as a closed feedback-loop: user data $D_t$, policies $P_t$, inferences $f_{P_t}(D_t)$, user appraisal $U(I_t)$, and corrective action $C_t$, with an iterative update [1412.6159].

- **Agentic AI Agency**: Modeled as an autonomous trajectory through composite action sequences $\tau_i = \{m_{i,j}, t_{i,j}, o_{i,j}\}$—reasoning, tool-use, observation—emerging from self-directed engagement with the environment, rather than prescription by external scripts [2509.17567].

- **Mixed-Initiative Taxonomies**: Agency is distributed ($A_D$) and allocated ($A_A$) between human and AI actors (e.g., Human-Driven, AI-Driven, Mixed-Initiative), each mode specified by control over decision-making and the loci of responsibility [2404.12056].

- **Ontological Conditions and Limits**: In the context of LLMs, agency is absent unless the system satisfies self-production (closure), endogenous norm creation (intrinsic value-regulation), and interactional asymmetry (origin of action)—which current LLMs lack [2407.10735].

These formalizations are instantiated in diverse architectures, protocols, and user experiences spanning interface design, autonomous agents, and hybrid intelligent systems.

## 2. Design Patterns and Formal Models

Agency-driven interaction modes are realized through a range of mechanisms rigorously grounded in mathematical models, control theory, and protocol design:

- **Shared Control via Optimal Control and Online Adjustment**: Multi-input control systems deploy a tunable parameter (e.g., $\lambda$) between human and automated actuation. Adaptive policies (actor-critic RL) online-adjust this blend in response to user state, optimizing cost and preserving perceived authorship [2502.13779].

- **Hypertextual Friction for Deliberative Agency**: In algorithmic feeds and generative tools, explicit introduction of “friction points" (decision forks), traceability (visible provenance chains), and structure (user-authored link graphs) implement an agency-driven paradigm by making user action and intention central [2507.23585].

- **Agency-Driven Governance in Negotiation Tasks**: Multi-role state machines (Principal, Delegate, Counterparty, Critic) instantiate agency boundaries, information-gated progression, and dual-channel feedback. Authorization predicates and preflight checks strictly delimit agent autonomy, with escalation mechanisms preserving ultimate human oversight [2511.06262].

- **Feedback and Human-in-the-Loop Correction**: Closed-loop architectures allow for user intervention at any stage—data correction, policy adjustment, or inference veto—supporting fine-grained, just-in-time agency modulation [1412.6159].

- **Operationalization in Learning Environments**: Agency is coded as observable epistemic (initiation, challenge, integration) and regulatory (reflection, coordination) acts, with transition networks and sequential motif mining revealing agency emergence and its modulation by AI participant persona [2512.18239].

- **Quantitative and Qualitative Agency Metrics**: Composite metrics across friction index, structure density, trace depth, task-correction rate, and perceived control (Likert or functionally measurable) allow comparative evaluation of agency-supporting systems [2507.23585][1412.6159][2401.00356].

## 3. Practical Applications and Case Studies

Agency-driven interaction is manifested across multiple domains:

| Domain                | Implementation Patterns                                         | Key Supporting Work         |
|-----------------------|----------------------------------------------------------------|----------------------------|
| Human–AI Data Science Collaboration | Open-ended chat (high agency) vs structured wizards (low agency); user can control both planning and execution | [2405.05548]               |
| Ridesharing Platforms | Transparent assignment, configurable preferences, feedback loops, dispute redress | [2401.00356]               |
| Live Collective Control | Audience voting drives robot performance, but choreography/ framing shape outcomes; felt vs actual agency divergence is explicit | [2506.10079]               |
| Generative AI Economy | Agents represent users/businesses, negotiating via A2A protocols for unscripted, sometimes unrestricted, market operations | [2505.15799][2512.22135]   |
| Accessible 3D Models  | Layered modalities (tactile, gesture, proactive voice); tiered agency from user-driven to mixed-initiative | [2009.00224]               |
| Cognitive Rehabilitation / XR  | FoA computed online from EEG markers modulates interface affordances to scaffold agency, with direct mapping from neurodynamics to UI adaption | [2509.07871]               |

Additional cases include AI-driven negotiation (bounded by preflight authorization and information-gated progression) [2511.06262], agent-based institutional design (BDI+FIPA protocols for transparency and accountable autonomy) [2511.17332], and data-centric HDI systems instrumented for correction loops and negotiation [1412.6159].

## 4. Agency in Artificial Agents and Emergent Machine Agency

Recent advances treat agency not as a static property but as an emergent, learnable trait in artificial systems:

- **Trajectory-Based Agency Benchmarks**: In LIMI, agency is the capacity to generate autonomous, multi-step solution trajectories via model reasoning, tool invocation, and outcome verification. Agency emerges through exposure to strategically curated, high-signal agentic demonstrations rather than data abundance, inverting classic scaling relations [2509.17567].

- **Mechanistic Interpretability**: Research into the mechanistic representation of agency in deep neural networks and the reinforcement learning of internal goals is proposed as foundational for safe, alignment-robust agentic systems [2509.17567][2511.17332].

- **Formal Agency Spectrum**: In predictive coding and active inference agents, agency-driven modes correspond to specific configurations of model complexity (e.g., KL-regularization weights in the ELBO), which tune the agent from egocentric leadership (tight complexity, strong self-prior) to follower imitation (loose complexity, high adaptation to others) [2002.01632]. The structural vs teleological distinction underlines whether autonomy is self-generated (biological/teleological systems) or externally imposed (structural artificial systems) [2512.06771].

- **Limits of Current LLMs**: Current LLMs, when isolated, fail to satisfy the conditions for autonomous agency (self-production, intrinsic normativity, interactional asymmetry) but may still produce new forms of “midtended" or hybrid human–machine agency when tightly coupled with human activity [2407.10735].

## 5. Evaluation, Measurement, and Trade-offs

Evaluation of agency-driven modes combines quantitative measurement, user/performance outcomes, and nuanced trade-off analyses:

- **Composite Scoring and Agency Indices**: Normalized sums of friction, traceability, and structure metrics, cognitive load reduction ratios (e.g., 72%–88% less vs RAG/manual workflows in SoDA), perceived control scores, and task correction/ completion rates are all in operational use [2507.23585][2512.22135][1412.6159].

- **Qualitative Perceptions, Trust, and Satisfaction**: Perceived agency (via NASA-TLX, SUS, or tailored sense-of-agency scales), satisfaction, and workload relate closely to the interaction mode—shared or adaptive agency significantly outperforms naive automation or rigid manual control [2502.13779][2512.18239].

- **Friction–Safety–Performance Triad**: Increasing user agency may trade off with efficiency, workload, and (if unchecked) risk—necessitating context-sensitive adaptation, transparency, and the capacity to reconfigure authority allocation in situ [2502.13779][2511.06262][2512.22135].

- **Feelings of Agency (FoA) as a Design Signal**: In neuroadaptive systems, real-time computation of FoA from affective engagement and volitional attention guides instant interface adaptation, closing the loop between phenomenological state and environmental affordance [2509.07871].

## 6. Open Challenges and Future Research Directions

Despite rapid progress, several challenges remain:

- **Standardization and Protocol Interoperability**: The agentic web demands broad adoption of common message schemas (e.g., MCP, A2A, UPDL), seamless migration of user memory, and decentralized yet trustworthy cross-agent discovery [2505.15799][2512.22135].

- **Scalable and Auditable Governance**: As agentic modes pervade negotiation, commerce, and B2B interaction, architectures must enforce bounded autonomy, auditability, and escalation protocols—balancing performance and risk [2511.06262][2511.17332].

- **Human–AI Co-regulation and Equity**: Dynamics of power, psychological safety, and ownership arise in emergent agency distribution (e.g., contrarian vs supportive AI personas in collaborative creativity show artifact trade-offs between productive friction and affective safety) [2512.18239].

- **Translational Neuroscience and Enactivist HCI**: New models of agency—focused on dynamical enaction, endogenous motivation, and the negotiation of affective-volitional coupling—inform next-generation interface tuning and adaptive tooling, but require robust, scalable real-time bio-signal integration [2509.07871].

- **Theoretical Foundations and Ontological Criteria**: Advancing agency in artificial systems will require architectures that go beyond script-following and reaction, embedding continual self-production, goal formation, and bidirectional coupling with open environments—pushing current models toward embodied, normative, and asymmetrically interactive regimes [2407.10735][2512.06771].

In summary, agency-driven interaction modes represent a research frontier spanning optimal interface and control design, robust governance and protocol interoperability, and deep questions of autonomy, normativity, and co-regulation. These approaches prioritize the user or agent’s ongoing capacity to shape, understand, and adapt outcomes—pushing beyond static alignment and toward evolving, participatory, and auditable intelligence systems [2502.13779][2507.23585][2512.22135][2401.00356][2511.06262][2509.17567][2404.12056][2509.07871][1412.6159][2407.10735].
