通过向参与者提供他们在测试期间食用的食物的照片图像，可以提高饮食回忆的准确性。我们研究了一个系统的可行性（图像饮食日），这是一个用户发起的摄像头配备的移动的电话，编程自动捕捉和传输图像到一个安全的网站，结合计算机辅助，多通道，24小时的饮食回忆在2007年期间在14名参与者。参与者在三个独立的日子中的每一天的进食期间使用该设备。图像处理滤镜成功地消除了曝光不足、曝光过度和模糊的图像。参与者在第二天完成24小时饮食回忆时，使用ImageViewer软件访问捕获的图像。没有参与者报告难以使用ImageViewer。93%的参与者认为图像“有帮助”或“有点帮助”。大多数（79%）用户表示没有技术问题，但71%的用户认为佩戴设备的负担有些困难，因为电池寿命有限，在公共场合佩戴设备的自我意识以及对相机视野的担忧。总的来说，这些研究结果表明，自动成像是一种很有前途的技术，以促进饮食回忆。可以应对管理生成的数千张图像的挑战。具有更宽视野的较小设备可以帮助克服用户在使用或佩戴设备时的自我意识
The accuracy of dietary recalls might be enhanced by providing participants with photo images of foods they consumed during the test period. We examined the feasibility of a system (Image-Diet Day) that is a user-initiated camera-equipped mobile phone that is programmed to automatically capture and transmit images to a secure website in conjunction with computer-assisted, multi-pass, 24-hour dietary recalls in 14 participants during 2007. Participants used the device during eating periods on each of the three independent days. Image processing filters successfully eliminated underexposed, over-exposed, and blurry images. Captured images were accessed by participants using the ImageViewer software while completing the 24-hour dietary recall on the following day. None of the participants reported difficulty using the ImageViewer. Images were deemed “helpful” or “sort of helpful” by 93% of participants. A majority (79%) of users reported having no technical problems, but 71% rated the burden of wearing the device as somewhat to very difficult, owing to issues such as limited battery life, self-consciousness about wearing the device in public, and concerns about the camera’s field of view. Overall, these findings suggest that automated imaging is a promising technology to facilitate dietary recall. The challenge of managing the thousands of images generated can be met. Smaller devices with a broader field of view may aid in overcoming user’s self-consciousness with using or wearing the device
