FINGER READER: A WEARABLE READING DEVICE
Finger-reader is an index-finger wearable device that supports the blind in reading printed text by scanning with the finger and hearing the words as synthesised speech . Our work features hardware and software that includes video processing algorithms and multiple output modalities, including tactile and auditory channels. The design of the Finger-reader is a continuation of our work on finger wearable devices for seamless interaction, and inspired by the focus group sessions. Exploring the design concepts with blind users revealed the need to have a small, portable device that supports free movement, requires minimal setup and utilises real-time, distinctive multi-modal response. The finger-worn design keeps the camera in a fixed distance from the text and utilises the inherent finger’s sense of touch when scanning text on the surface. Additionally, the device provides a simple interface for users as it has no buttons, and affords to easily identify the side with the camera lens for proper orientation.

The Finger-reader hardware features tactile feedback via vibration motors, a dual-material case design inspired by the focus group sessions and a high-resolution mini video camera. Vibration motors are embedded in the ring to provide tactile feedback on which direction the user should move the camera via distinctive signals. Initially, two ring designs were explored: 4 motor and 2 motor. Early tests with blind users showed that in the 2 motor design signals were far easier to distinguish than with the 4 motor design, as the 4 motors were too close together. This led to a new, multi-material design using a white resin-based material to make rubbery material for the flexible connections. The dual material design provides flexibility to the ring’s fit as well as helps dampen the vibrations and reduce confusion for the user.
