A Comparative Study of Younger and Older Adults' Interaction with a Crowdsourcing Android TV App for Detecting Errors in TEDx Video Subtitles

TL;DR

This study compares how younger and older adults interact with a crowdsourcing Android TV app for subtitle error detection, revealing differences in focus, motivation, and cognitive load, with implications for designing accessible subtitle QA systems.

Contribution

It provides insights into age-related differences in interacting with TV-based crowdsourcing systems for subtitle quality assurance.

Findings

Younger adults focus more on error detection; older adults focus on meaning and entertainment.

Interaction was intuitive, fun, but cognitively demanding, especially for younger users.

Recommendations for designing age-inclusive TV-enabled crowdsourcing tasks.

Abstract

In this paper we report the results of a pilot study comparing the older and younger adults' interaction with an Android TV application which enables users to detect errors in video subtitles. Overall, the interaction with the TV-mediated crowdsourcing system relying on language profficiency was seen as intuitive, fun and accessible, but also cognitively demanding; more so for younger adults who focused on the task of detecting errors, than for older adults who concentrated more on the meaning and edutainment aspect of the videos. We also discuss participants' motivations and preliminary recommendations for the design of TV-enabled crowdsourcing tasks and subtitle QA systems.
