Abstract
Examples of sensing a human touch to a touch screen and providing tactile and visual feedback are disclosed.
Claims20
A method comprising:
- receiving, by a computing device, an input responsive to a user's touch on a surface of a first layer of a touch screen;
- generating an input signal associated with the input;
- providing tactile feedback responsive to the user's touch via one or more micro electromechanical machines (MEMs) included in a second layer of the touch screen, the second layer of the touch screen being below the first layer of the touch screen and including at least one piezoelectric crystal;
- and
- providing visual feedback via a third layer of the touch screen based on the input signal, the third layer of the touch screen being below the second layer of the touch screen,
- wherein receiving the user's touch on the surface of the first layer comprises:
- inducing a voltage across the second layer by compressing the at least one piezoelectric crystal in the second layer in response to the user's touch on the surface of the first layer, and
- inducing the tactile feedback provided via the one or more MEMs using the voltage induced across the second layer.
5 more elements
An apparatus comprising:
- a first layer to generate an input signal in response to receiving a user's touch on a surface of the first layer, the input signal associated with a user input to a computing device;
- a second layer, positioned below the first layer, to provide tactile feedback responsive to the user's touch, the second layer including one or more micro electromechanical machines (MEMs) and at least one piezoelectric crystal;
- and
- a third layer, positioned below the second layer, to provide visual feedback responsive to the input signal generated by the first layer,
- wherein the third layer is configured to display the visual feedback simultaneously with the tactile feedback,
- wherein the visual feedback comprises an indicator configured to identify an intended action associated with the input signal to provide a visual confirmation to indicate that a user has made an intended selection, and
- wherein the first layer:
- induces a voltage across the second layer by compressing the at least one piezoelectric crystal in the second layer in response to the user's touch on the surface of the first layer, and
- induces the tactile feedback provided via the one or more MEMs using the voltage induced across the second layer.
6 more elements
A system comprising:
- at least one processor and memory;
- and
- a touch screen comprising:
- a first layer to generate an input signal in response to detection of a user's touch on a surface of the first layer, the input signal associated with a user input,
- a second layer to provide tactile feedback responsive to the user's touch, wherein the second layer includes one or more micro electromechanical machines (MEMs) and the one or more MEMs comprise at least one piezoelectric crystals, and
- a third layer to provide visual feedback responsive to the input signal generated by the first layer,
- wherein the third layer is above the second layer and below the first layer, and
- wherein the first layer:
- induces a voltage across the second layer by compressing the at least one piezoelectric crystal in the second layer in response to the user touch on the surface of the first layer, and
- induces the tactile feedback provided via the one or more MEMs using the voltage induced across the second layer.
