The method measures the capacitance of each sensor. The method identifies a peak unit cell based on the measured capacitances and calculates an edge cutoff value. A plurality of unit cells with measured capacitances within a range defined by the edge cutoff value are selected and the position of the hovering object is calculated. In some embodiments, the array comprises a first plurality of capacitance sensing electrodes disposed along a first axis and a second plurality of capacitance sensing electrodes disposed along a second axis. In some embodiments, the array and a controller form a user interface device, and the controller is configured to calculate the position of the conductive object using the method described above."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hover position calculation in a touchscreen device","description":"A method calculates the position of a conductive object hovering above a plurality of mutual capacitance sensors, where each mutual capacitance sensor is represented as a unit cell in an array of unit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9684409","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
