Abstract: Styli for generating alert notifications to prevent unintentional marking of interactive devices are disclosed. A disclosed stylus includes a housing and a processor. The housing is to interchangeably receive a physically marking nib and an electronic marking nib. The processor is carried by the housing. The processor is to determine a received nib is the physically marking nib. The processor is further to determine a distance between the stylus and an interactive device satisfies a threshold. The processor is further to generate an alert notification based on the received nib being the physically marking nib and the distance between the stylus and the interactive device satisfying the threshold.

Abstract: Examples disclosed herein involve calibrating an input device to a display using the input device. An example method includes determining first coordinates of a position-encoded film corresponding to a location of an input device relative to the position-encoded film of a display of a computing device based on first position points of the position-encoded film, determining second coordinates of a pixel array corresponding to the location of the input device relative to the pixel array of the display based on a first reference pixel of the display, measuring a first offset between the first coordinates of the position-encoded film and the second coordinates of the pixel array, and calculating a calibration transformation to control the computing device based on the first offset.
