  • Publication number: 20210240283
    Abstract: A typing profile based mood sensing system may comprise a processor receiving a user identification associated with a personal typing profile identifying a repeated pattern of values for a combination of previously recorded haptic hardware typing or touch behavior parameters, and a piezo haptic keyboard controller operably connected to piezo electric elements situated beneath keys of the piezo keyboard detecting current haptic hardware typing or touch behavior parameters describing deformation characteristics for the piezo electric elements. The processor may compare the user personal typing behavior profile against the current haptic hardware typing or touch behavior parameters to identify a user personal typing behavior profile value change, and associate the change with a mood-based haptic keyboard setting adjustment. The piezo haptic keyboard controller may apply the mood-based haptic keyboard setting adjustment to operation of the haptic keyboard or touchpad.

  • Publication number: 20210240805
    Abstract: A piezo haptic keyboard and touchpad user identification system may comprise a processor receiving an authenticating user input identifying an authorized user of the information handling system, and a controller operably connected to a plurality of piezo electric elements situated beneath the keyboard. The controller may detect haptic hardware typing or touch behavior parameters describing characteristics of a plurality of deformations of the piezo electric elements during interaction between the authorized user and the keyboard, and the processor may use machine learning to identify a repeated pattern of values for a combination of the haptic hardware typing or touch behavior parameters reoccurring during interaction between the authorized user and keyboard. The processor may associate the repeated pattern of values for the combination of the haptic hardware typing or touch behavior parameters with the authorized user for later, passive authentication of a user based on typing dynamics.

  • Patent number: 10585451
    Abstract: A portable information handling system transforms between clamshell and all-in-one positions by sliding a display housing pivot axis towards a front side of a main housing and raising the rear side of the main housing with a stand that extends out from a bottom surface of the main housing. A keyboard detaches from the main housing upper surface to expose guides that manage the display housing sliding motion towards the main housing front side. The all-in-one position raises the main housing towards a near-vertical orientation to raise the display above a support surface for end user viewing while an end user interacts with the keyboard separated from the housing.

  • Patent number: 10558244
    Abstract: A portable information handling system stand couples to a main housing lower surface with a dual axle hidden stand hinge that extends the stand parallel to the main housing lower surface with an initial synchronized opposing rotation of the axles by a predetermined amount, such as 45 degrees, and then rotates out a stand supporting end with rotation of one axle while the other axle remains stationary. Initial parallel extension of the stand reduces the amount of space in the main housing lower surface consumed by rotational movement of the stand to an extended position.
