Error Behaviours in Natural User Interfaces

自然的用户界面使用户能够通过触摸、语音命令和手势与计算机交互。它们被誉为人机交互的下一步进化。这样的接口有望使与技术系统的交互变得更加容易。例如，指着一盏灯并发出打开它的命令，而不是使用灯开关的间接方法。Flowton Technologies为自然用户界面开发了一个新平台。鉴于识别技术总体上并不完美，主要的可用性问题集中在失败案例上，更重要的是，用户对此类错误的反应。这一核心问题将决定最终产品的可行性。Flowton已经尝试了各种反馈方法，但还无法确定有效的解决方案。

Natural user interfaces enable users to interact with computers via touch, spoken commands, and gestures. They have been hailed as the next evolutionary step in human-computer interaction. Such interfaces promise to make it even easier to interact with technical systems. An example is pointing to a lamp and issuing a command to turn it on, instead of using the indirect means of a light switch. Flowton Technologies has developed a new platform for natural user interfaces. Given that recognition technologies are not perfect in general, the main usability problems center on the failure cases and, more importantly, the reaction of users to such errors. This central issue will determine the viability of the final product. Flowton has experimented with various feedback methods, but has not been able to determine an effective solution.
