【摘要】：随着大屏幕智能设备的普及和不断发展,它的应用逐步渗入到我们生活的各个角落。然而,与之配套的文本输入系统却一直没能得到很好的发展,一直采用传统的以五向按键作为操作基础的遥控器设备来完成文本字符的输入。该输入设备在进行字符输入时需要不断地按动按键来切换不同的字符选择,输入速度慢、操作复杂。如何减少字符输入时按键按动的次数,提高该字符输入的速度成为大屏幕智能设备上一个亟待解决的问题。本文正是在这样的背景下,设计了一款以手势动作作为输入源的基于加速度计和陀螺仪传感器的英文文本输入系统原型,具体研究内容如下:第一、对现有手势识别的方法进行了充分调研,对系统原型所需手势识别方法进行了深入分析。第二、对字符输入的过程进行了全面的分析,根据完成一个字符输入所必须经过的步骤设计了两种用于完成输入任务的交互手势。第三、在分析交互手势运动特点的基础上,遵循启发用户,降低用户学习成本原则,设计了两款虚拟键盘布局样式。第四、通过实验验证了本文所设计的英文文本输入方式在输入速度上优于传统的遥控器输入方式,同时,扇形虚拟键盘布局方式优于圆形虚拟键盘布局方式。采用灵活、自由的手势操作代替传统遥控器设备字符输入时的按键操作,从本质上改变了字符输入的方式,而且它更加直观、自然,能有效地降低用户的学习成本。本文的研究内容对新的文本输入方式的研究有着一定的参考意义。
[Abstract]:With the popularization and development of large-screen intelligent device, its application gradually seeps into every corner of our life. However, the corresponding text input system has not been well developed, and has been using the traditional five-direction key as the operating basis of the remote control device to complete the text character input. The input device needs to press the key constantly to switch different character selection, which makes the input speed slow and the operation complex. How to reduce the number of keystrokes in character input and improve the speed of character input has become an urgent problem in large screen intelligent equipment. In this paper, a prototype of English text input system based on accelerometer and gyroscope sensor is designed based on gesture action as input source. The main contents are as follows: first, The existing gesture recognition methods are fully investigated, and the gesture recognition methods required by the prototype of the system are deeply analyzed. Secondly, the process of character input is analyzed comprehensively, and two kinds of interactive gestures are designed to complete the input task according to the steps that a character input must go through. Thirdly, on the basis of analyzing the characteristics of interactive gesture movement and following the principle of inspiring users and reducing the learning cost of users, two virtual keyboard layout styles are designed. Fourthly, the experiment proves that the English text input mode designed in this paper is superior to the traditional remote controller in input speed, and the sector virtual keyboard layout is better than the circular virtual keyboard layout. The use of flexible and free gesture operation to replace the traditional remote control device character input keystroke operation essentially changes the character input way and it is more intuitive and natural which can effectively reduce the user's learning cost. The research content of this paper has certain reference significance to the research of new text input mode.
