本文从广泛的视角研究了注视打字系统对残疾人的可用性，该视角考虑了使用场景以及这些系统所惠及的特定用户。确定了注视打字系统的设计目标：每分钟超过25个单词的输入效率、稳健的追踪、高可用性以及对多模式输入的支持。对丹麦和日本的注视打字系统的效率和用户满意度进行了详细调查，并将其与头部打字和鼠标（手）打字进行了比较。我们发现注视打字比其他两种方式错误更多。注视打字与头部打字速度一样快，且两者都比鼠标（手）打字慢。讨论了设计改进的可能性。
This paper investigates the usability of gaze-typing systems for disabled people in a broad perspective that takes into account the usage scenarios and the particular users that these systems benefit. Design goals for a gaze-typing system are identified: productivity above 25 words per minute, robust tracking, high availability, and support of multimodal input. A detailed investigation of the efficiency and user satisfaction with a Danish and a Japanese gaze-typing system compares it to head- and mouse (hand) - typing. We found gaze typing to be more erroneous than the other two modalities. Gaze typing was just as fast as head typing, and both were slower than mouse (hand-) typing. Possibilities for design improvements are discussed.
