力敏多级输入元件被引入作为移动环境中紧凑尺寸输入设备的基本构建块。与开关式按键相比，多级元件可以在保持输入容量的同时减少键盘上的按键数量。在具有多模式反馈的三级三元件触觉和弦系统中演示了使用力敏感传感器垫的多级输入机制。引入了两种方案将传感器的输出范围分段。对于相对缺乏经验的用户来说，基于最大手指力的方案给出的平均错误率为20.2%，对于三个输入的和弦，输入时间为2.24 s。使用高斯分割对实验数据进行重新分类表明，可以预期性能会显着提高。
Force-sensitive multilevel input elements are introduced as the basic building blocks for compact-size input devices in mobile environments. Compared with switch-type keys, multilevel elements can decrease the number of keys on a keyboard while maintaining the input capacity. A multilevel input mechanism using force-sensitive sensor pads is demonstrated in a three-level three-element tactile chording system with multimodal feedback. Two schemes are introduced to segment the output range of the sensor into levels. For relatively unpracticed users, the scheme based on maximum finger forces gives an average error rate of 20.2% and an input time of 2.24 s for a chord of three inputs. Reclassification of the experimental data using Gaussian segmentation shows that significant improvement of the performance can be expected.
