Abstract

In this paper, we present a novel method to take photos with a hand-held camera. Cameras are being used for new purposes in our daily lives these days, such as to augment human memory or scan visual markers (e.g. QR-codes) and opportunities to take snapshots are increasing. However, taking snapshots with today's hand-held camera is troublesome, because its viewfinder forces the user to see the real space through itself, and it requires complicated operation to control zoom levels and press a shutter-release button at the same time. Therefore, we propose ClippingLight that is a combination method of Projection Viewfinder and tilt-based zoom control. It enables to take snapshots with low effort. We implement this method using a prototype of real-world projection camera. We conducted user study to confirm the effect of CippingLight in situations to take photos one after another. As a result, we found that ClippingLight is more comfortable and requires lower effort than today's typical camera when a user takes a photo quickly.

ClippingLight:一种带有投影取景器和基于倾斜的变焦控制的简单快照方法

本文提出了一种用手持相机拍摄照片的新方法。如今，相机在我们的日常生活中被用于新的用途，例如增强人类记忆或扫描视觉标记(例如qr码)，拍摄快照的机会也在增加。然而，用今天的手持相机拍照很麻烦，因为它的取景器迫使用户通过自己看到真实的空间，并且需要复杂的操作来控制变焦级别并同时按下快门释放按钮。因此，我们提出了ClippingLight，这是一种结合投影取景器和基于倾斜的变焦控制的方法。它可以轻松地拍摄快照。我们使用一个真实世界的投影相机原型来实现这个方法。我们通过用户研究来确认CippingLight在一个接一个拍照的情况下的效果。因此，我们发现，当用户快速拍照时，ClippingLight比现在的典型相机更舒适，也更省力。
