Tactile Pin Array Device
First Claim
1. ) An electronic device having tactile feedback, comprising:
- a processor, memory, storage, and a power source;
one or more cameras for capturing one or more simultaneous images;
a pin array comprising at least one pin assembly;
each pin assembly comprising a pin head that is height adjustable using an electric motor, said pin head having a fully extended state and a fully retracted state;
a pin array controller for controlling each of said electric motors.

Abstract
A handheld electronic device having a tactile pin array thereon is provided for assisting those with vision impairments. The device comprises a set of cameras that can capture a forward image, whereby the image is processed and used to output a three dimensional representation of the image on the tactile pin array. This allows one to recognize objects and obstacles in the area in front of the device, while the pin array may also be deployed as an adaptive braille reader. A specific pin assembly is contemplated using a micro stepper motor, while the overall system provides several functions for visually impaired users, including navigation capabilities, facial recognition, connection to wireless networks, and various input/output means.

9. ) A method of providing tactile feedback, comprising the steps of:
-
capturing one or more images of an area using one or more cameras; processing said one or more images for depth and spatial relation of objects in said area; transforming said depth and spatial relation into machine-readable data; using a pin array controller to transform said machine-readable data into individual commands for an array of pin assemblies along a pin array; moving each of said pin assemblies to correspond with said individual commands as to create a tactile representation of said objects in said area using said pin array. - View Dependent Claims (10)
