Glanceable Data Visualizations for Older Adults: Study on Age Disparities

Q: How can smartwatch design be improved to accommodate aging users?

To improve smartwatch design for aging users, several considerations should be taken into account. Firstly, the font size and visual elements on the smartwatch display should be larger and easily readable to accommodate age-related changes in vision, such as presbyopia. Providing options for customizable text sizes and contrast settings can enhance readability for older adults. Additionally, simplifying the interface by reducing clutter and unnecessary information can make it easier for older users to navigate. Furthermore, incorporating tactile feedback or haptic cues can assist older adults in interacting with the device without solely relying on visual cues. This feature can provide confirmation of actions taken on the watch without requiring precise touch inputs. Moreover, designing intuitive gestures and navigation patterns that are easy to learn and remember can enhance usability for aging users. Clear icons and symbols that are universally understood can also aid in making interactions more straightforward. Incorporating voice commands or virtual assistants like Siri or Google Assistant can offer an alternative interaction method for older adults who may have difficulty with small buttons or touchscreens. Voice-activated features allow hands-free operation of the smartwatch, improving accessibility for those with dexterity issues.

Q: What are the implications of these findings for technology accessibility?

The findings regarding glanceable data visualizations for older adults have significant implications for technology accessibility across various domains. By understanding how aging affects perception and cognition when interacting with visual data on devices like smartwatches, designers and developers can create more inclusive interfaces that cater to a diverse range of users. One implication is the need to prioritize user-centered design principles that consider age-related changes in vision, cognitive abilities, motor skills, and overall technological proficiency among older adult populations. By tailoring interfaces to meet these specific needs through larger fonts, simplified layouts, clear contrasts between elements, intuitive navigation paths,and other accessible features will ensure that technology remains usable by all individuals regardless of age. Additionally,the study highlights the importance of conducting research focused on underrepresented demographics,such as older adults,to promote inclusivity in technology development.By addressing barriers faced by this population group,it sets a precedentfor creating more accessible productsand servicesacross different technologies beyond justsmartwatches.

Основні поняття

Older adults exhibit varying performance in glanceable data visualizations, with age impacting time thresholds and preferences.

Анотація

The study replicates a perceptual experiment on smartwatch visualizations with older adults aged 65 and above. It explores the impact of aging on perception, cognition, and decision-making related to data visualization. The research aims to establish empirical thresholds for older adults in interpreting glanceable visualizations and highlights the influence of age on graphical perception. The findings suggest that Donut charts are preferred by older adults, followed by Bar charts, while Radial charts show the slowest performance. Performance declines as data complexity increases, especially for Radial charts. The study also compares performance between younger and older adults, as well as between young-old (65-74) and old-old (75+) participants.

INTRODUCTION

Glanceable visualizations enable quick insight discovery.
Older adult population is rising globally.
Smartwatches pose challenges due to small fonts.
Aging affects perception and cognition.

STUDY DESIGN AND EXECUTION

Replication study on smartwatch visualizations with older adults.
Participants aged 65+ recruited from local community groups.
Sony SmartWatch 3 used for stimuli presentation.
Two-alternative forced choice approach employed.

DATA ANALYSIS AND RESULTS

Time Thresholds:

Older adults perform best with Donut charts.
Performance gap widens for Radial charts.

Accuracy:

Both young-old and old-old participants meet or exceed expected accuracy levels.

Strategies:

Participants use various strategies based on chart types (Bar, Donut, Radial).

Preference and Confidence Ratings:

Older adults prefer Donut charts over Bar and Radial.
