Gesture Wand for Mobile Devices

描述(申请人提供)：这个项目的主要目标是开发一种手势棒，对老年人特别有用，以克服与移动设备中用户界面尺寸减小相关的问题。这将专门针对那些可能损害他们的视力或手动灵活性的个人。由于技术的进步，移动设备将变得越来越小。随着这些设备的尺寸减小，它们的用户界面也将缩小。这给老年人带来了一个特殊的问题，他们经历了与年龄和疾病相关的视力和手动灵活性下降。当尝试与小型移动设备连接时，这些损失可能会导致严重问题。鉴于人口老龄化和紧凑型技术的日益普及，使用小型移动设备的老年人数量将继续增加。我们对界面问题的解决方案是一种界面，它使用自由空间中的魔杖移动，具有音频确认和反馈功能。利用三维加速度计MEMS芯片和单芯片与微控制器的无线连接(即蓝牙)，将快速开发出手势棒原型。手势棒快速原型将用于确定适合老年人使用的移动设备虚拟界面中的最佳手势。具体的手势将是数字和控制命令。手势将使用隐马尔可夫模型进行识别，将手势分解为连续的符号。棒上的微控制器将被编程进行预处理和特征提取。移动设备将使用可能手势的隐马尔可夫模型来比较传入数据。使用开发的手势棒硬件和软件，我们将测试至少36名60岁及以上视力或手动灵活性技能受损或两者兼而有之的人的概念验证。在短暂的培训之后，他们将被要求使用手势棒输入数字和特定的控制命令。如果90%的人能够在90%的时间内可靠地操作原型手势棒，而不考虑视力或操纵技能问题，这一目标就会成功。该项目的主要目标是开发一种对老年人特别有用的手势棒，以克服与移动设备中用户界面尺寸减小相关的问题。这将专门针对那些可能损害他们的视力或手动灵活性的个人。

DESCRIPTION (provided by applicant): The primary goal of this project is to develop a gesture wand that will be especially useful to older individuals to overcome problems associated with the decreasing size of the user interface in mobile devices. This will be targeted exclusively to individuals who may have their vision or manual dexterity compromised. Due to advances in technology, mobile devices will become increasingly smaller. As the size of these devices decreases, their user interfaces will also shrink in size. This presents a special problem for older adults, who experience age and disease related decrements in vision and manual dexterity. These losses can cause significant problems when attempting to interface with small mobile devices. Given the aging demographic of the population and the increasing availability of compact technologies, the number of older adults using small mobile devices will continue to increase. Our solution to the interface problem is an interface using movement of a wand in free space that has audio confirmation and feedback. A gesture wand prototype will be quickly developed using 3-D accelerometer MEMS chip and a single chip wireless connection (i.e. Bluetooth) with microcontroller. The gesture wand quick prototype will be used to determine the best gestures for use in a mobile device virtual interface for older age individuals. The specific gestures will be numbers and control commands. The gestures will be recognized using a Hidden Markov Model to break the gestures down into sequential symbols. The microcontroller on the wand will be programmed for preprocessing and feature extraction. The mobile device will compare the incoming data using the Hidden Markov Model of possible gestures. Using the gesture wand hardware and software developed, we will test the proof of concept with at a least 36 individuals age 60 and older who have their vision or manual dexterity skills compromised or both. After a short training session, they will be asked to use the gesture wand to enter numbers and specific control commands. Success of this aim will be if 90 % of the people can reliably operate the prototype gesture wand 90 % of the time in spite of vision or manipulative skill problems. The primary goal of this project is to develop a gesture wand that will be especially useful to older individuals to overcome problems associated with the decreasing size of the user interface in mobile devices. This will be targeted exclusively to individuals who may have their vision or manual dexterity compromised.
