A system includes a first ultrasound transmitter acoustically coupled to a conducting layer of a display surface and configured to deliver a first ultrasound wave to a selected delineated area. The first ultrasonic wave has parameters sufficient to induce a non-linear vibrational response in the conducting layer. A second ultrasound transmitter is acoustically coupled to the conducting layer and configured to deliver a second ultrasound wave to the selected delineated area. The second ultrasonic wave has parameters sufficient to induce a non-linear vibrational response in the conducting layer. A controller selects a delineated area in response to an indication of a touch to the display surface, and initiates delivery of the first and second ultrasonic waves. A convergence of the first and second ultrasonic waves at the selected delineated area produces a stress pattern perceivable or discernible by the human appendage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tactile feedback generated by non-linear interaction of surface acoustic waves","description":"Described embodiments include a system and a method.
