The USPTO granted Apple a series of patents this week, however, this article holds a particular focus on the filtering of unintended contacts detected on the touch-sensitive surface. The patent also holds a particular reference to wet environments, as that is when surface sensitivity is largely detected and can lead to a disturbance in the touch performance of the device.
The patent sets the example of touch paths (likely intended input) and non-touch paths, (likely unintended input as a result of contact to wet fabric). The division of different inputs into paths could possibly reduce processing requirements and save power of the Apple Watch. The non-touch paths can just be rejected by the intelligent algorithm.
This patent is in particular reference to the Apple Watch as this is one of the Apple devices likely to come into immediate contact with a wet sleeve for example, without the knowledge of the owner. There should also be a consideration put into place if a user intendedly entered information onto the device, however, the Watch mistakes it for a non-touch path. The granting of the patent doesn’t necessarily mean this will become a feature of the iWatch, however, it is highly likely, as it can improve efficiency, battery life, and user convenience.
