Decoding Digital Aging: Personas for Elderly Facebook Interaction on Mobile
17849_A study of elderly users' interaction with Facebook on mobile devices identification and definition of the personas.
This paper presents a Human-Computer Interaction (HCI) study focused on elderly users' behavior on Facebook via mobile devices. It proposes a set of data-driven "Personas" to categorize the interaction patterns and accessibility needs of this specific demographic within social networking contexts.
TL;DR
As the global population ages, the "digital divide" is shifting from access to usability. This research identifies and defines specific Personas for elderly users interacting with Facebook on mobile devices. By moving away from a one-size-fits-all approach, the study provides a framework for designing social interfaces that respect the cognitive and physical nuances of older adults.
The "Invisible" User: Why General Design Fails the Elderly
Most social media platforms are designed with "digital natives" in mind—users who possess high levels of interface intuition and fine motor coordination. However, for users aged 60 and above, the mobile experience is often fraught with hidden obstacles.
The researchers argue that the primary pain point isn't just a lack of interest, but a mismatch between Inductive Bias (how the developer expects the user to act) and the actual capabilities of the elderly. Previous studies often grouped "the elderly" into a single bucket, ignoring the vast differences between a retired professional who is tech-savvy and a first-time smartphone user.
Methodology: From Observation to Personas
To bridge this gap, the authors employed a qualitative HCI approach. They focused on:
- Contextual Inquiry: Observing how elderly users hold their devices and navigate the Facebook app.
- Behavioral Mapping: Identifying recurrent patterns in how they post, comment, and use the "Like" button.
By synthesizing this data, the study moved beyond demographic statistics to create "Personas"—fictional yet data-driven characters that represent specific segments of the elderly user base.

Key Personas and Interaction Barriers
The research highlights that interaction is heavily influenced by Digital Literacy and Social Motivation.
- The Information Consumer: Focuses on reading news and family updates but rarely interacts due to fear of "breaking the system" or making a public mistake.
- The Active Communicator: High social motivation but struggles with the precision required for small mobile buttons (the "Fat Finger" problem).
The study identified that the Hamburger Menu and multi-layered navigation in Facebook often lead to a "lost in hyperspace" feeling for these users.

Critical Insight: Beyond Font Size
The "takeaway" for the tech industry is profound. Simple UI "fixes" like increasing font size (Accessibility 101) are insufficient. The real challenge lies in Information Architecture.
The study suggests that:
- Reducing Hierarchical Depth: Elderly users prefer flat navigation.
- Explicit Feedback: Every touch must result in a clear, unambiguous visual or haptic response to build user confidence.
- Error Tolerance: Designs should assume a higher rate of accidental clicks.
Conclusion and Future Outlook
This paper serves as a critical reminder that the "elderly" are not a monolithic demographic. As we move toward more AI-driven interfaces, incorporating these personas into the training of UI-generation models could lead to more inclusive digital environments. The limitation of the study lies in its focus on a specific geographic region (Brazil), but the behavioral insights regarding cognitive load and motor skills are globally applicable.
Future work should explore how these personas evolve as "Silver Surfers" (those who grew up with PCs) enter the 70+ age bracket, potentially shifting the digital literacy baseline.
