�� Switch to external sound recording due to poor
internal recording
�� However, there is no microphone, earphone
microphone is not recognized.

03. Problems
(4) Difficulty in using QT Creator
(5) ui Design: Image output
(6) Implementation of multi-touch �� QT
(7) Insufficient QT recording data

World Information Architecture Day 2025 - UX at a CrossroadsJoshua Randall

User Experience stands at a crossroads: will we live up to our potential to design a better world? or will we be co-opted by ��product management�� or another business buzzword? Looking backwards, this talk will show how UX has repeatedly failed to create a better world, drawing on industry data from Nielsen Norman Group, Baymard, MeasuringU, WebAIM, and others. Looking forwards, this talk will argue that UX must resist hype, say no more often and collaborate less often (you read that right), and become a true profession �� in order to be able to design a better world.
