Development of a Smart Device Cradle with Automatic Distance Adjustment Using Face Tracking Technology

To make the use of smart devices convenient to users such as patients confined to hospital beds and persons with disabilities, a smart device cradle that can recognize the user's movement and automatically adjust the distance of the smart device is needed. In this study, we proposed to develop a cradle that can automatically adjust the position of the smart device and its distance from the user. A face tracking technology recognizing the user's face and utilizing facial features and a reservation function to automatically move the cradle as required were applied to the development. The developed and manufactured smart device cradle was able to maintain suitable distance based on the position of the user's face and move automatically for the user to easily see the smart device.
