An Intuitive and Efficient Data Transmission Method to Surrounding Mobile Devices with the Manner of Taking a Picture

如今，通常使用诸如蜂窝电话或PDA的嵌入有相机的移动的设备。当这些设备的用户拍摄照片并希望将其发送给他们周围的一些人时，他们需要逐个选择单个移动终端。然而，这种重复的选择对于用户来说是耗时的工作。用户还可以使用电子邮件或无线通信系统（例如蓝牙）进行传输，但是从一长串列表中选择预期的移动的设备是耗时的。在本文中，提出了一种方法，直观和有效地传输图片到周围的预期移动的设备。在该方法中，用户可以通过类似于拍摄它们的照片的方式来选择设备。实验结果表明，该方法比传统方法具有更短的设备选择时间。该方法具有直观、易学的特点。

Nowadays, mobile devices embedded with a camera such as cellular phones or PDAs are commonly used. When users of such devices take a picture and want to transmit it to some of people around them, they need to select individual mobile device one by one. However, such repeated selection is time consuming work for users. Users can also transmit using e-mail or wireless communication system, such as Bluetooth, but it is time consuming to choose intended mobile devices from a long list. In this paper, a method is proposed for transmitting pictures intuitively and efficiently to surrounding intended mobile devices. In this method, users can choose the devices by the similar way as taking a picture of them. As the result of experiment, it is found that the time to select the intended devices with the proposed method is shorter than with traditional methods. It is also found that the proposed method is intuitive and easy to learn its usage.
