An Image Acquisition Subsystem For Tactile Vision Substitution
The desired properties of an image acquisition subsystem for Tactile Vision Substitution (TVS) are defined, and the developed subsystem is presented. An effective and practical subsystem has properties such as real-time response and accurate imaging in any realistic situation. The hardware that acquires the visual information is a small autofocusing video camera interfaced to computer electronics. The processing software includes three options for image presentation which will enable future studies for improving object recognition and portable operation. The developed subsystem achieved the desired results and is effective for TVS.
