专业的交互技术，如热键是有效的，但很少采用，因为它们很难学习。HotStrokes消除了学习命令到热键的任意映射的需要。用户通过按住修改键输入HotStroke，然后在笔记本电脑触控板上输入命令名称，就像在虚拟键盘上一样。手势识别使用SHARK2算法与新的空间模型和动态建议的改进方法的适应。控制实验表明，HotStrokes有效地增强了现有的“菜单和热键”命令激活范例。结果表明，该方法是有效的，通过减少43%的命令激活时间相比，线性菜单。该方法也易于学习，采用率高，取代了91%的线性菜单使用。最后，结合线性菜单、热键和HotStrokes，命令激活速度总体上提高了24%。
Expert interaction techniques like hotkeys are efficient, but poorly adopted because they are hard to learn. HotStrokes removes the need for learning arbitrary mappings of commands to hotkeys. A user enters a HotStroke by holding a modifier key, then gesture typing a command name on a laptop trackpad as if on an imaginary virtual keyboard. The gestures are recognized using an adaptation of the SHARK2 algorithm with a new spatial model and a refined method for dynamic suggestions. A controlled experiment shows HotStrokes effectively augments the existing "menu and hotkey" command activation paradigm. Results show the method is efficient by reducing command activation time by 43% compared to linear menus. The method is also easy to learn with a high adoption rate, replacing 91% of linear menu usage. Finally, combining linear menus, hotkeys, and HotStrokes leads to 24% faster command activation overall.
