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.

描述（由申请人提供）：该项目的主要目标是开发一种手势棒，该手势棒对老年人特别有用，以克服与移动的设备中用户界面尺寸减小相关的问题。这将是专门针对个人谁可能有他们的视力或手动灵活性受损。由于技术的进步，移动的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。这对老年人来说是一个特殊的问题，他们经历了与年龄和疾病相关的视力和手灵活性下降。当尝试与小型移动的设备接口时，这些损耗可能会导致严重的问题。鉴于人口老龄化和小型技术的日益普及，使用小型移动的设备的老年人数量将继续增加。我们的解决方案的接口问题是一个接口，使用移动的魔杖在自由空间，有音频确认和反馈。手势棒原型将使用3-D加速度计MEMS芯片和与微控制器的单芯片无线连接（即蓝牙）快速开发。手势棒快速原型将用于确定老年人移动终端虚拟界面中使用的最佳手势。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来识别，以将手势分解为顺序符号。将对Wand上的微控制器进行编程，以进行预处理和特征提取。移动终端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名年龄在60岁及以上的人的概念证明，他们的视力或手动灵活性技能受到损害或两者兼而有之。经过短暂的训练后，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，尽管存在视觉或操纵技能问题，则该目标将获得成功。这个项目的主要目标是开发一个手势棒，这将是特别有用的老年人，以克服与移动的设备中的用户界面的尺寸减小相关的问题。这将是专门针对个人谁可能有他们的视力或手动灵活性受损。
