尽管摄影是一种视觉媒介，但视障人士使用智能手机相机拍照。我们提出了一个智能手机应用程序，它可以帮助视障人士正确的目标，同时采取肖像照片。我们已经实现了两个组成（中央，黄金比例）和两个反馈方式（语音，振动）的目标辅助算法。在一项有12名蒙眼参与者的研究中，我们比较了四种组合（构图×反馈方式）在瞄准时间、互动、完成时间、照片的美学质量和使用舒适度方面的差异。结果表明，黄金比例构图与语音反馈相结合产生了最佳的瞄准时间（5.53秒）和完成时间（8.33秒），照片的美学质量最好，被认为是最舒适的。双击的交互时间平均为2.92秒，四种组合之间没有显著差异。
Even though the photography is a visual medium, visually impaired people use their smartphone cameras to take photos. We present a smartphone application, which helps visually impaired people to properly aim while taking portrait photographs. We have implemented an aiming assistance algorithm for two compositions (central, golden-ratio) and two feedback modalities (voice, vibration). In a study with 12 blindfolded participants we compared four combinations (composition × feedback modality) in aiming time, interaction, completion time, aesthetic quality of photos, and comfort of use. The results show that the combination of golden ratio composition with voice feedback produced the best aiming time (5.53 seconds) and completion time (8.33 seconds), the best aesthetic quality of photos, and was perceived as most comfortable. The interaction time of double click was 2.92 seconds on average and there was no significant difference between the four combinations.
