  • Patent number: 12315080
    Abstract: Methods and systems are provided for determining a posture of a user of an Information Handling System (IHS). One or more cameras of the IHS are utilized to generate a two-dimensional image of the user as they operate the IHS. Landmarks that correspond to physical features of the user are identified through processing of the two-dimensional image generated using the cameras. The system then identifies, from a database comprising a plurality of differing wireframes, a subset of the wireframes that optimally match the physical feature landmarks of the user, each of the wireframes associated with an ergonomic level, and performs a regression analysis technique on the ergonomic level of each of the subset of wireframes to determine a posture score of the user.

  • Patent number: 12067744
    Abstract: Systems and methods detect the posture of a user of an IHS (Information Handling System). An image is generated of a user and of the physical environment in which the user is operating the IHS. The image is processed to generate segregated images of the user and of the physical environment. The segregated image of the physical environment is classified as corresponding to a known environment in which the user has operated the IHS and that is associated with a probability of an ergonomic posture being used while in that particular environment. The segregated image of the user is processed to determine a physical posture of the user relative to the IHS. An ergonomic risk score is generated based on deviations of the user's posture from an ideal posture. The ergonomic risk score is scaled based on the probability of an ergonomic posture being used, due to the environment.

  • Patent number: 11868551
    Abstract: Methods and systems for providing computer implemented services using user input are disclosed. To obtain the user input, a human interface device may be used. Interpretation of actuation of the human interface device may be customized to the types of actuations that users are able to perform. To customize the types of the actuations, users may perform actuations of the human interface device for various types of user input to establish associations between the actuations and the user input. The associations may be used to train an inference model usable to identify user input based on performed actions of the human interface device.
