• Primary objective: This report moves the Product Genome from a conceptual framework into an evidence-driven research program. The initial framework proposed that product design could be studied through recurring variables such as affordance, feedback, mapping, constraint, ergonomics, materials, manufacturing, durability, repairability, and emotional attachment. It also suggested beginning with Dieter Rams and Richard Sapper as contrasting designer genomes. The largest uncertainty was whether the principles common…
• Primary claims/evidence: - “Less” should be treated as removal of unnecessary burden, not reduction of visible parts or features by default. - Product complexity has at least four distinct forms: functional, interactional, representational, and structural. - Complexity can be relocated rather than eliminated. - The core unit of usability is the human-object-environment relationship, not the object alone. - Perceived action possibility and actual action possibility must be evaluated separately. - Compatibility with lear…
• Methodology: The original ecological concept is relational. An affordance exists between an organism, an object, and an environment. It includes actual bodily capability, not merely what an object looks like it can do. A handle that visually suggests grasping but cannot be comfortably reached by the intended population is not a successful affordance. It is a signifier attached to a failed action possibility.
• Limitations/known uncertainties: Remaining Uncertainty: The most important unresolved issue is quantification. We can identify dimensions of product legibility, but do not yet know how to combine them into a reliable predictive score. The second major uncertainty is transferability. Evidence fr… Attempted Falsification: A strong form of the minimalism hypothesis predicts that a single multifunction control should outperform several dedicated controls. Evidence from divided-attention contexts contradicts that prediction. Dedicated controls can support tact… Attempted Falsification: The strongest version of direct affordance predicts that instruction-free products should be superior. This fails for products where action consequences are hidden, delayed, dangerous, or dependent on internal state. The opposite theory, t… Attempted Falsification: The original hypothesis predicts that adding vibration to a touchscreen should never match a physical control. Existing evidence contradicts this. Engineered haptics can improve touch interaction and may be emotionally preferred in some co… Attempted Falsification: HYP-004A predicts that a product held together with standard screws is repairable. This fails if paired components, unavailable parts, or adhesive-sealed subassemblies block the actual repair path. HYP-004B predicts that emotionally evocat… Attempted Falsification: If Rams were simply a reducer, his modular furniture systems would avoid expansion and reconfiguration. They do not. Their value depends on structured extensibility. If Sapper favored complexity for its own sake, Tizio would expose its ele… CF-002: Control behavior that violates established user expectations increases use-error risk: FDA guidance uses directional control behavior as a concrete example. Compatibility is therefore a safety variable, not merely an aesthetic preference. Confidence: High. CF-009: Tactile feedback can improve performance in tasks where vision is limited or augmented: Motor-learning and prosthetic-control studies support measurable benefits under certain conditions. Confidence: Moderate-high. EP-004: Good Feedback Reduces Epistemic Uncertainty: Feedback does more than create pleasure. It tells the user: - whether the action registered; - whether the state changed; - how much it changed; - whether the action is complete; - whether correction is needed.

Five highest-value opportunities

Challenge and confidence decay

The source was challenged for construct validity, independent replication, boundary conditions, transfer, and comparative baselines. Confidence should decay when the source lacks a dated replication, when its technology or target population changes, or when later artifacts report contradictory findings. Revalidation is recommended before treating context-bound recommendations as universal.
