We present a mobile head-mounted device for detecting and tracking text that is encased in an ordinary flat-cap hat. The main parts of the device are an integrated camera and audio webcam together with a simple remote control system, all connected via a USB hub to a laptop. A near to real-time text detection algorithm (around 14fps for $\mathbf{640\times 480}$ images) which uses Maximal Stable Extremal Regions (MSERs) for image segmentation is proposed. Comparative results against the ICDAR 2003 text locating competition database along with performance figures are presented.
