当今可用的传统触觉界面使用电机来产生力，而更新的一类设备则使用无源元件来限制运动。本文提出了一种新的混合驱动方法，结合了制动器、弹簧和电机的使用。所提出的驱动设计可能比仅依赖电机驱动的触觉设备更安全、更节能，并且还克服了现有无源触觉显示器所显示的许多渲染限制。这项新技术的应用范围从安全性和可靠性至关重要的设备（例如大型力反馈接口）到只能由小型电池等有限能源供电的设备（例如便携式触觉接口）。
Traditional haptic interfaces available today use motors to generate forces, while a more recent class of devices uses passive elements to constrain movement. This paper presents a new hybrid actuation approach that combines the use of brakes, springs and motors. The proposed actuation design is potentially safer and more energy efficient than haptic devices that only rely on motors for actuation, and also overcomes many of the rendering limitations displayed by existing passive haptic displays. Applications of this new technology range from devices where safety and reliability are of prime concerns (e.g. large force-feedback interfaces) to devices which can only be powered by limited energy sources such as small batteries (e.g. portable haptic interfaces).
