Narrative很不起眼，很容易被误认为是领带夹。它没有按键和显示屏，只有一个功能：每隔30秒拍下它面前的景象。一天下来就有超过2,000张照片，其画质堪比iPhone 4的摄像头。

A sensor makes sure the photos are always upright, no matter how the clip is oriented, while a GPS chip inside notes where you are each time it takes the photo. Tap on the Narrative twice and it will snap a photo right away.

无论相机处于何种方位，它的感应器都会确保照片端正。同时，内置的GPS芯片会记录每张照片的拍摄地点。连续敲击两下，相机就会立刻抓拍一张。

The pricier Autographer is three times larger, making it flop over when I attached it to my shirt pocket. It packs a 5-megapixel camera with fisheye lens and five sensors -- including an accelerometer, compass and thermometer -- in order to take a picture when it thinks your surroundings have changed. It can use Bluetooth to transfer shots wirelessly to a phone or computer right away. All of this extra tech means the battery lasts about 10 hours, compared with the Narrative's 30.

Autographer价格较贵，比Narrative大三倍，夹在衬衫衣兜上会外翻。它配置了一个500万像素的鱼眼镜头和五个传感器――其中包括加速计、指南针和温度计――这使它能感知周遭环境变化，及时拍照。它还可通过蓝牙即时把快照无线传输到手机或电脑上。所有这些额外的技术配置意味着它的电池只能续航约10小时，而Narrative是30小时。
