为了更容易地将美国手语(ASL)添加到网站,这将增加许多聋人用户的信息可访问性,我们调查软件,从易于更新的消息脚本半自动生成ASL动画,要求我们自动选择动画的速度和时间。虽然我们可以从视频记录中模拟人类签名者的速度和时间,但之前的工作表明,用户更喜欢动画比人类签名者的视频慢。然而,没有先前的研究系统地检查了ASL时序的多个参数,包括:符号持续时间,过渡时间,暂停频率,暂停持续时间和差异符号率。在一项实验研究中,16个本地ASL签名者提供了主观偏好的判断,在并排比较ASL动画,其中每一个这五个参数是不同的。我们凭经验确定并报告用户对ASL动画的这些单独的定时参数中的每一个的偏好。
To make it easier to add American Sign Language (ASL) to websites, which would increase information accessibility for many Deaf users, we investigate software to semi-automatically produce ASL animation from an easy-to-update script of the message, requiring us to automatically select the speed and timing for the animation. While we can model speed and timing of human signers from video recordings, prior work has suggested that users prefer animations to be slower than videos of humans signers. However, no prior study had systematically examined the multiple parameters of ASL timing, which include: sign duration, transition time, pausing frequency, pausing duration, and differential signing rate. In an experimental study, 16 native ASL signers provided subjective preference judgements during a side-by-side comparison of ASL animations in which each of these five parameters was varied. We empirically identified and report users' preferences for each of these individual timing parameters of ASL animation.
