振动和听觉反馈的显著进步已经将触摸屏从简单的视觉输入/输出设备转变为高度交互和多模式的设备。虽然听觉反馈在听写就足够的任务中是有用的，但在需要解释图形的任务中，听觉反馈可能是乏味的和有限的。在这项工作中，我们专注于探索程序，图形的识别精度，以及如何在较小的规模重复可以帮助用户识别类似的图形时，只有振动反馈是在触摸屏上使用。我们进行了形状识别任务，56名被试蒙眼。结果表明，用户能够可靠地识别基本的2D形状在90秒内只使用触觉反馈。用户也能够识别较小的形状与薄振动边界的速度与他们的较大的同行后，暴露在较大的形状第一。我们还观察成功的探索性程序，并比较用户之间的方法。这些发现有助于通知非视觉界面设计使用触摸屏上的触觉反馈功能。
Considerable advancements in vibratory and auditory feedback have transformed the touchscreen from a simple visual input/output device to one that is highly interactive and multimodal. While auditory feedback is useful in tasks where dictation is sufficient, it can be tedious and limited in tasks that require interpretation of graphics. In this work, we focus on exploration procedures, identification accuracy of graphics, and how repetition at smaller scales may help users identify similar graphics when only vibratory feedback is used on touchscreens. We conducted shape identification tasks with 56 blindfolded participants. Results suggest users are able to reliably identify basic 2D shapes within 90 s using only haptic feedback. Users were also able to identify smaller shapes with thin vibrating borders at rates comparable to their larger counterparts after being exposed to the larger shapes first. We also make observations on successful exploratory procedures employed and compare approaches among users. These findings serve to inform non-visual interface design using haptic feedback capabilities on touchscreens.
