Electronic device for measuring hydrature using display and method for operating the same

A method in an electronic device, comprising:

• setting at least one operational attribute of a capacitive sensor using a first value,
• acquiring, by at least one processor, a first data measurement from the capacitive sensor in when an external object contacts a display while the at least one attribute is set using the first value and determine that a touch input has occurred based on the first data,
• when the touch input satisfies a prespecified condition:
• reduce a frequency of a signal input to the capacitive sensor to change at least one of a charging rate or a discharging rate of the capacitive sensor,
• acquiring a second data measurement from the capacitive sensor while the external object contacts the display, when the at least one operational attribute is set using the second value, and
• determining a hydration value associated with the external object at least based on the acquired second data measurement, and
• when the touch input does not satisfy the prespecified condition, maintain the frequency.

An electronic device, comprising:

• a display including a capacitive sensor;
• and
• at least one processor configured to:
• set at least one operational attribute of the capacitive sensor using a first value,
• when a touch input is received and the touch input has an area greater than a predetermined area:
• reduce a frequency of a signal input to the capacitive sensor to change at least one of a charging rate or a discharging rate of the capacitive sensor,
• acquire a first data measurement from the capacitive sensor while an external object contacts the display when the at least one operational attribute is set using a first value, and
• determine a hydration value associated with the external object at least based on the acquired first data measurement,
• when the touch input is not received or when the area of the touch input is less than the predetermined area, maintain the frequency.
