Systems and methods described herein provide a haptic feedback system and method for touch-based function row keyboards that leverages existing components on laptop computers to provide tactile feedback for users when a touch function row key is pressed. According to one embodiment, an Information Handling System (IHS) includes a keyboard with a touch function row having multiple touch keys, a mouse pad with one or more electro-acoustic transducers, and executable instructions that receive a message indicating that one of the touch keys of the touch function row has been pressed. In response to the received message, the instructions actuate at least one of the electro-acoustic transducers to provide haptic feedback for the one pressed touch key.

Haptic feedback system and method for touch function row keyboards

A multi-state keyboard function row is provided. A plurality of representations can be formed on an insert of the multi-state keyboard function row. An assembly of the multi-state keyboard function row can be configured to cause either a first set of the representations or a second set of the representations to be visible to a user. A brightness of the representations may also be controlled based on a brightness of ambient light.

An information handling system with a hybrid Universal Serial Bus Type-C (USB-C) port architecture and method for operating the same comprising a USB-C port for communicating display graphics signals to a plurality of peripheral device types attachable to the USB-C port where the USB-C port is operably connected to a high throughput data translation hub via a first data bus capable of transmitting the display graphics signal at least at 8.1 Gbit/s across at least four lanes and the high throughput data translation hub is operably connected to a dedicated discrete graphics processing unit (dGPU) and operably connected to a CPU with integrated GPU (iGPU) operating with lower graphics processing capacity and power than the dGPU. A USB-C controller executing code instructions of the hybrid USB-C head mounted display interface management system to instruct the USB-C port to operate in a first mode or in a second mode depending on identification of a peripheral device type attached to the USB-C port where the USB-C port is operably connected to a first multiplexing circuit via a second data bus for transmitting USB data wherein the first multiplexing circuit is capable of operating in the first mode to operably connect USB data from the USB-C port to the USB-C controller, and the first multiplexing circuit is capable of operating in the second mode to operably connect the dGPU to the USB-C port via a USB data line parallel to the first data bus.
