A New Patent Application Published For Using Apple Pencil With iPhone
Apple Pencil support for iPhones have been highly anticipated ever since Tim Cook accidentally confirmed that its on it way. A new patent has been published which chronicles the technology behind using the pencil with a smartphone.
The touch sensing system may perform one or more coarse input device sub-scans to determine a coarse location of the input device.
The coarse location can be used to select one or more touch sensors (or sensor channels) to sample for decoding data encoded in the stimulation signals from the input device.
During one or more fine input device sub-scans, the touch sensing system can determine a fine location of the input device and decode the data from the input device sampled from the selected touch sensors (or sensor channels).
The sketches accompanying the patent resemble the iPhone even though the patent talks generically about ‘touchscreen devices’.
Some reports suggest that 2019 iPhones will even retail with a mini Apple Pencil although this seems far-fetched.
