富威集团代理产线Invensense推出IDG-650/ ISZ-650应用游戏摇杆陀螺仪 实现准确手势追踪

 2011-04-27
富威集团代理产线Invensense推出IDG-650/ ISZ-650,增加运动传感之游戏机台与手持游戏机,增添了新的互动空间。要求近乎真实情境的1:1游戏新体验,便需要游戏处理技术(多轴陀螺仪与其他传感器之结合运用)。应用于游戏摇杆的陀螺仪,提供关键性旋转资讯,并不像磁场计或加速器般易受干扰。为改进新的Wii Motion Plus配件之运动处理功能,任天堂引用了InvenSense的多轴陀螺仪,使反应更快,并实现了准确的3D游戏手势追緃。

如同Wii Motion Plus,应用于游戏之陀螺仪的主要要素为宽广的全格传感范围(wide full scale range)、高轴间隔绝(high cross-axis isolation)、极佳震动排除(superior vibration rejection)、高机械碰撞容忍度(high mechanical shock tolerance),以及小尺寸。InvenSense的IDG-650可完全满足这些规格要求,提供±2,000°/sec的全格传感范围、< ±1%的轴间隔绝、10,000g的碰撞容忍度,以及4x5x1.2mm的包装尺寸。ISZ-650单轴(Z)陀螺仪可补足IDG-650双轴(X/Y)陀螺仪,提供将所有传感器与其他系统电子组装于同一平面的解决方案。

InvenSense功能特点
•量测快速动作的最高传感范围可达±2,000°/sec的全格传感范围(full scale range)
•每轴皆具两个独立的输出端,各自提供标准与高感应传感输出,可使用较低分辨率之类比数位转换器(analog-to-digital convertors,ADC)来降低系统成本。
•IDG-650之特性为整合于单一芯片之同平面设计,拥有卓越的X/Y轴间校准(cross-axis alignment)。ISZ-650单轴(Z)陀螺仪可补足IDG-650双轴(X/Y)陀螺仪,提供所有传感器与其他系统电子组装于同一平面的三轴陀螺仪解决方案。
•特殊的芯片设计与制程,达成良好抖动排除效果
•10,000g之最高碰撞容忍度
•自动归零设定功能(auto-zero function)降低偏压飘移(bias drift)
•大小为4x5x1.2mm之世界最小尺寸双轴陀螺仪
•Nasiri-Fabrication 制程平台之设计优势,包含尺寸、效能与成本,是其他制程无法相比的
