本文介绍了Humsher -一种新颖的文本输入方法操作的非语言的声音输入，特别是哼唱的声音。该方法利用自适应语言模型进行文本预测。四个不同的用户界面，并进行了比较。其中三个使用动态布局，其中n元字符呈现给用户选择，根据他们的概率在给定的上下文中。最后一个界面采用静态布局，其中字符显示和修改的二进制搜索算法是用于一个有效的选择一个字符。所有的接口进行了比较，并在一项用户研究，涉及17个健全的科目进行评估。还进行了案例研究，以验证该方法对运动障碍用户的潜力。最快界面的平均速度是每分钟14个字符，而最快的用户达到每分钟30个字符。残疾参与者在七次会议后能够以每分钟14 - 22个字符的速度打字。
This paper presents Humsher -- a novel text entry method operated by the non-verbal vocal input, specifically the sound of humming. The method utilizes an adaptive language model for text prediction. Four different user interfaces are presented and compared. Three of them use dynamic layout in which n-grams of characters are presented to the user to choose from according to their probability in given context. The last interface utilizes static layout, in which the characters are displayed alphabetically and a modified binary search algorithm is used for an efficient selection of a character. All interfaces were compared and evaluated in a user study involving 17 able-bodied subjects. Case studies with four disabled people were also performed in order to validate the potential of the method for motor-impaired users. The average speed of the fastest interface was 14 characters per minute, while the fastest user reached 30 characters per minute. Disabled participants were able to type at 14 -- 22 characters per minute after seven sessions.
