为何重要
移动端输入慢且易错,打几个字就能选中可大大省力(Bast & Weber, 2006)。不会拼写也能搜索,且需即时更新,速度很关键。参见移动搜索UX。
数量与顺序
选项越多决策越慢(希克定律;Hick, 1952)。建议不超过10个,移动端更少(Moran, 2018)。用户注视靠前项(Hofmann et al., 2014),应把最可能的放上面(Cai & de Rijke, 2016)。
移动端与无障碍
行高要适合拇指(Parhi et al., 2006;触控目标尺寸),不被键盘遮挡。遵循ARIA组合框模式(W3C, n.d.)。
常见问题
- 建议几个合适?
- 移动端一般5至8个。
- 输入的字要加粗吗?
- 通常强调补全的部分。
