Overview
ISO/IEC TR 29194:2015 - Information Technology - Biometrics - Guide on designing accessible and inclusive biometric systems provides practical guidance for designing, specifying and procuring biometric systems that are accessible to the widest reasonably possible target population. It complements earlier, higher‑level guidance (notably ISO/IEC TR 24714‑1) by offering modality‑specific examples and an accessibility taxonomy to support inclusive system design and exception handling during deployment.
Key Topics
- Accessible and inclusive design taxonomy - classifies users by inability to perform functions (visual, auditory, motor, physiological, cognitive, cultural), enabling clear specification of which user categories the primary biometric solution must support and which require exception handling.
- Modality coverage - guidance spans common biometric modalities described in ISO/IEC 19794 (all parts): finger, face, iris, signature, vascular, hand‑geometry, and voice.
- Modality‑specific guidance - sections address problems and recommendations for:
- inability to perceive visual information (Section 4)
- inability to perceive auditory information (Section 5)
- inability to perform motor actions (Section 6)
- inability to present physiological attributes (Section 7)
- inability to understand or apply instructions (Section 8)
- cultural or language discrepancies (Section 9)
- Generic recommendations and sources - high‑level design and procurement advice, plus pointers to additional accessibility resources.
- Quantification and acceptance - supports defining target populations, measurable accessibility goals and acceptance testing criteria for procurement.
Applications
ISO/IEC TR 29194:2015 is practical for:
- System designers and vendors - to design sensors, user interfaces and capture workflows that minimize exclusion and improve usability across diverse populations.
- Procurement officers and program managers - to write clear, testable accessibility requirements and acceptance tests for biometric purchases.
- Accessibility specialists and usability testers - to assess whether biometric solutions meet population coverage goals and to define exception‑handling processes.
- Policy makers and integrators - to evaluate modality selection, multi‑modal strategies and fallback mechanisms for inclusive services (border control, voting, health services, workplace access, financial services).
Benefits
- Improves inclusion and reduces failure rates at point of use
- Provides a common taxonomy for dialogue between procurers and suppliers
- Helps specify measurable acceptance tests and exception handling
