    • Techniques are provided for a gesture device to detect a series of gestures performed by a user and execute corresponding electronic commands associated with the gestures. The gesture device detects a gesture constituting movements from a user in three-dimensional space and generates a confidence score value for the gesture. The gesture device selects an electronic command associated with the gesture and compares the electronic command with a prior electronic command associated with a prior gesture previously detected by the gesture device in order to determine a compatibility metric between the electronic command and the prior electronic command. The gesture device then adjusts the confidence score value based on the compatibility metric to obtain a modified confidence score value. The electronic command is executed by the gesture device when the modified confidence score value is greater than a predetermined threshold confidence score value.
    • 为手势设备提供了用于检测由用户执行的一系列手势并且执行与手势相关联的相应电子命令的技术。 手势装置检测构成来自三维空间中的用户的移动的手势,并且生成用于手势的置信度得分值。 手势装置选择与手势相关联的电子命令,并将电子命令与先前由手势装置检测到的先前手势相关联的先前电子命令进行比较,以便确定电子命令和现有电子命令之间的兼容性度量。 手势装置然后基于兼容性度量来调整置信度得分值,以获得经修改的置信度得分值。 当修改的置信度分数值大于预定的阈值置信度得分值时,由手势装置执行电子命令。
