Abstract

Providing accessibility path guidance on a display presented on a touch screen of a device with microfluidics. The fluid is selectively applied to a portion of the touch screen by a computer of the device to raise a portion of the touch screen. The computer loads a display on the touch screen which requires user input. The flow information regarding the display is fetched and a computer of the device detects that the user has touched the touch screen at a point. The computer uses microfluidics to create a physical ridge on the touch screen corresponding to a flow path connecting the point on the touch screen in which the user is currently touching to a touch point within an object field which requires user input. Once the user has reached the object field by following the physical ridge through touch, the physical ridge is removed.
