Abstract: 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.

Abstract: In one example, a hinge assembly is disclosed, which may include a first member and a second member rotatably connected to the first member through a mounting portion. The mounting portion may include a first surface having a first protrusion and a second surface, opposite the first surface, having a second protrusion. Further, the hinge assembly may include a first cam fixed to the first member and disposed adjacent to the first surface and a second cam fixed to the first member and disposed adjacent to the second surface. The first cam and second cam being engageable with the first protrusion and the second protrusion, respectively, to shift an axis of rotation of the second member.

Abstract: In an example, an accessory holder may include an expandable loop movable between a stowed position within a housing of a device chassis and a deployed position. When in the deployed position, the expandable loop may extend out of the housing to receive and hold a device accessory. The example accessory holder may further include a bias member to urge the expandable loop towards the stowed position.

Abstract: Examples herein relate to a hinge. In some examples, a hinge can include a first bracket connected to a shaft, a second bracket connected to the first bracket, a member connected to the shaft and magnetically attracted to a magnet at a first position, where the member translates relative to the magnet to a second position as the shaft rotates about an axis of the shaft, and the magnet to generate a magnetic attraction force between the member and the magnet, where the magnetic attraction force is higher at the second position than the first position.
