Developing affordance model of smartphone user interface for older adults
With a global increase in population ageing, Malaysia is expected to be an aged nation by 2035. Concurrent with the change in the demographic composition, smartphones have become ubiquitous mobile communication tools for a growing proportion of older adults in Malaysia. However, the older adults...

| description |
With a global increase in population ageing, Malaysia is expected to be an aged
nation by 2035. Concurrent with the change in the demographic composition,
smartphones have become ubiquitous mobile communication tools for a
growing proportion of older adults in Malaysia. However, the older adults are
generally perceived as technophobic. Smartphone user interface (UI) and some
mobile apps are not designed to meet the needs and expectations of older adults.
The gap in perception and intended use hinders older adults from fully utilizing
the functions and services of a smartphone. Affordance is defined as ‘perception
and possibilities of actions for users (older adults) while interacting with an object
(smartphone UI).’ This study refers to Norman’s Execution/Evaluation Action
Cycle (EEAC) model and Gaver’s Technology Affordance.
This study aims to develop an affordance model on perception and action
possibilities of smartphone UI for older adults. A conceptual framework and
hypothetical model of the study were formulated. This research employs
multiphase design mixed methods methodology. Phase 1 is a preliminary study
using quantitative method (survey). This is followed by Phase 2 consisting of
mobile-user interaction study using mixed methods which is ‘concurrent
embedded design’ (questionnaire, observation, and interview). Results from
Phase 1 indicate smartphone usage among the older adults and justification of task design for Phase 2. The sample size for Phase 2 study was 80 ‘young-old’
adults, from 60 to 74 years old.
To validate the affordance model, merged data analysis strategies were
performed for quantitative and qualitative data. The empirical study indicates
that 11 out of 16 hypotheses are supported. It is concluded that the affordance
model is supported by the empirical findings. The major contribution of this
study is the development of an affordance model, which is considered novel and
adds value to the body of knowledge for Human-Computer Interaction and
Gerontechnology. Based on the findings, it is crucial to incorporate older adults’
needs and expectations to reduce affordance gap with the underlying affordance
matrix. |
