Techniques for proving haptic feedback in computing systems are described. In operation, an input representing utilisation parameters of an electronic pen is received. In an example, the electronic pen may be electronically coupled to the computing system. Based on the received utilisation parameters, the computing system provides a pattern of haptic feedback to the user.

Haptic feedback for computing systems

In some examples, an electronic device includes a tip pressure sensor to capture tip pressure data based on a writing surface. In some examples, the electronic device includes a processor to produce a classification of the writing surface based on the tip pressure data via a machine learning model. In some examples, the electronic device may include a haptic device to control haptic feedback based on the classification.

Surface classifications

In one example, an input pen may include an electronic component, a communication interface to establish a short-range wireless connection with an electronic device, and a controller communicatively coupled to the electronic component and the communication interface. The controller may receive a command from the electronic device via the communication interface. The command may uniquely correspond to an operating mode of the electronic device. Further, the controller may control a power state of the electronic component based on the command.

Active stylus power management design

An example stylus pen may include a main body including a first battery and a writing tip attached to the main body. Further, the stylus pen may include a cap removably disposed on the main body to cover the writing tip. The cap may include a second battery. Furthermore, the stylus pen may include a controller to charge the first battery from the second battery.
