Abstract:
A method for touch detection on an ungrounded pen enabled device includes sampling output in a frequency range of a signal emitted from a stylus over a stylus sampling window, detecting touch input from a finger or hand based on detecting a gain between a touch threshold and a stylus threshold, wherein the touch threshold is below the stylus threshold over at least two consecutive columns and two consecutive rows of the sensor and reporting coordinates of the touch input based on detecting the touch input. Stylus input is detected based on detecting a gain above a stylus threshold in at least one column and one row of the sensor and coordinates of the stylus are reported based on stylus input being detected. Sampling is performed simultaneously from both columns and rows of a grid based capacitive sensor.

Claim (Index 11):
A method comprising:\n determining that a device that includes a grid based capacitive sensor is either grounded or ungrounded; and sampling output of the grid based capacitive sensor over a plurality of sampling windows; performing mutual capacitive detection over a first sampling window from the plurality; sampling output from both columns and rows of the grid based sensor over a second sampling window from the plurality, wherein the output is sampled without driving the column or rows with a driving signal emitted by a controller configured to operate the grid based capacitive sensor; identifying a heatmap based on the mutual capacitive detection over the first sampling window; identifying areas of touch input from the output sampled over the second sampling window based on determining that the device is ungrounded; comparing the heatmap to the areas of touch input identified based on determining that the device is ungrounded; and reporting coordinates of touch based on the comparing.
