A design research for understanding how to use desk top products from case shapes

本研究旨在寻找一种用户界面输入设备外壳的形状设计模式，让用户在没有指令的情况下就能理解使用。我们尝试了两个实验，并比较了这些结果。第一个实验是思维模拟，第二个是物理模型实验。结果，我们观察到每个形状之间相同的共同动作多于不同的单独动作，动词单词和实际动作不匹配。特别是，“震动”在每一个形状中都能被观察到，即使使用加速度计也更容易感觉到。总之，这项研究表明，我们有可能使用一个形状来引导用户进行更多不同的动作，这个形状可以在像桌子表面这样的空间上留下更多不同的轨迹，而不是形状形式。

This research aims to find the shape design pattern of an input device case for user interface that let users understand to use without instruction. We tried two experiments and compared these results. The first experiment is mind simulation, the next is physical-model experiment. As the result, we observed more same common actions than different individual actions between each shapes, not matching verb words and real actions. In particular, "shaking" is observed in every shapes, and easier to sense even with an accelerometer. In conclusion, this research suggests us a possibility to lead users more various actions using a shape which can leave more various trajectories against space like table surface rather than shape forms.
