Abstract: Systems and methods for human hand gesture recognition through a training mode and a recognition mode are disclosed. In the training mode, a user can move a handheld device with a hand gesture intended to represent a command. Sensors within the handheld device can record raw data, which can be processed to obtain a set of values corresponding to a set of discrete features, which is stored in a database and associated with the intended command. The process is repeated for various hand gestures representing different commands. In the recognition mode, the user can move the handheld device with a hand gesture. A computer system can compare a set of values corresponding to a set of discrete features derived from the hand gesture with the sets of values stored in the database, select a command with the closest match and displays and/or executes the command.

Abstract translation: 公开了通过训练模式和识别模式进行人手手势识别的系统和方法。 在训练模式中，用户可以用旨在表示命令的手势来移动手持设备。 手持设备内的传感器可以记录原始数据，其可以被处理以获得对应于一组离散特征的值，其存储在数据库中并与预期命令相关联。 对于表示不同命令的各种手势重复该过程。 在识别模式下，用户可以用手势移动手持设备。 计算机系统可以将对应于从手势派生的一组离散特征的值与存储在数据库中的值集合进行比较，选择具有最匹配的命令并显示和/或执行该命令。

Abstract: A method, system and computer readable medium for calibrating an accelerometer in a portable device is disclosed. The method, system and computer readable medium comprises receiving data from the accelerometer, and providing accelerometer samples from the data based upon one or more selection rules that adaptively selects data that satisfy certain criteria. The method system and computer readable medium also includes fitting the accelerometer samples to a mathematical mode. The method system and computer readable medium further includes providing a bias of the accelerometer based upon a center of the mathematical model.
