Key Findings

  • 01Accessibility and usability share commonalities in areas like consistency and user control.
  • 02Accessibility concerns primarily revolve around essential functions, while usability often relates to psychological factors, additional features, and personal preferences.
  • 03Users with disabilities encounter significant difficulties with kiosk operations and physical access.
02

Application

Design takeaway

Prioritize the design of core functionalities for universal access before layering on features that cater to individual preferences or advanced usability.

How to apply

When designing any interactive interface, first map out the absolute essential tasks a user must complete. Ensure these tasks are navigable and operable by individuals with diverse abilities, then proceed to enhance the experience with secondary features.

Project actions

  • 01When researching user needs, clearly differentiate between what is a fundamental requirement for use versus what is a desirable enhancement.
  • 02Use focus groups to gather rich qualitative data on user experiences, particularly from underrepresented groups.

Method & Evidence

AimWhat are the distinct characteristics of accessibility and usability in the context of interactive kiosks, and how do they relate to the experiences of people with disabilities?
MethodQualitative research
ProcedureA literature review was conducted to analyze the concepts of accessibility and usability. Subsequently, focus group interviews were held with individuals experiencing visual, hearing, and physical impairments to gather insights into their challenges with kiosk usage. The findings were then analyzed to delineate the characteristics of accessibility and usability and to illustrate their relationship.
ContextInteractive kiosk design in public spaces

Variables

IVDesign characteristics of kiosks (e.g., interface layout, physical access, feature set)
DVUser experience of kiosks (measured by perceived usability and accessibility, task completion success, user satisfaction)
CVParticipant demographics and disability types, kiosk context
04

Strengths & Limitations

Strengths

  • +Addresses a critical gap in understanding the relationship between accessibility and usability for emerging technologies.
  • +Employs qualitative methods to capture nuanced user experiences.

Limitations

Focus group findings are subjective and may not represent the full spectrum of user experiences. The specific kiosk technology and environment studied might not apply to all scenarios.

Reliability & validity

Reliability could be enhanced by using standardized usability metrics alongside qualitative feedback. Validity is supported by the focus on real-world user experiences and the distinction between functional requirements and preferences.

Think critically

How might a design that heavily prioritizes subjective usability over essential accessibility inadvertently exclude significant user groups?

05

Design Principles

"Essential functions must be universally accessible before subjective usability enhancements are considered."

This distinction is crucial for ensuring that kiosks are not only functional but also truly inclusive. By separating and prioritizing essential accessibility needs, designers can create interfaces that are usable by a wider range of individuals, preventing exclusion and enhancing the overall user experience.

What This Means for Your Design

When making something like a self-service machine, make sure everyone can do the basic things it's supposed to do first, before adding extra cool features that only some people might want.
