小红点为何有力
仅收到通知就会降低表现(Stothart et al., 2015),打断提高速度与压力(Mark et al., 2008),恢复任务需要时间(Iqbal & Horvitz, 2007)。
习惯与徽标疲劳
短暂查看的习惯让手机使用更频繁(Oulasvirta et al., 2012),而通知本已很多(Pielot et al., 2014)。为琐事加徽标接近黑暗模式。参见通知权限请求。
圆点、数字与无障碍
数量不重要用圆点,重要用数字,大数写成“999+”(Google, n.d.)。查看后立即消失,在底部导航上不遮挡文字。按WCAG 2.2的1.4.1,不能只靠红色,应以文字播报。
常见问题
- 圆点与数字何时用?
- 只需知道有新内容用圆点,数量重要用数字。
- 徽标何时消失?
- 用户查看后立即消失。
