Abstract: A change of a resource allocation scheme in a multi-pen supporting electronic apparatus can be made in a shorter period of time than in the prior art. A sensor controller 50 assigns communication resources to one or more pens 2, respectively, and detects a position of each of the one or more pens 2 on the basis of a downlink signal DS received from each of the one or more pens 2 using the assigned communication resources. When changing a resource allocation scheme, which indicates a structure of the communication resources or a method of using the communication resources, the sensor controller 50 broadcasts information indicating a new resource allocation scheme to the one or more pens 2.

Abstract: Described are methods and systems for auto framing an object of interest. A webcam of an information handling system captures a full field of view image that has a region of interest (ROI) that includes a pointing element, such as an active pen, user finger, or other such object. The ROI also includes the object of interest. An auto-framing AI/ML model detects the ROI and the pointing element and auto-frames the object of interest to which the pointing element is directed to.

Abstract: A mobile terminal device includes a display section having a display screen, an input section having a touch input region on the display screen, and a control section for displaying a plurality of keys. The display screen is provided as a software keyboard where a touch operation on a specific key causes an input of the specific key. In the specific display region on the display screen that can display operation keys on the software keyboard, the control section selects these keys from a previously prepared set of input candidate key groups. In response to a specific operation on the specific display region, the control section allows the plurality of keys to be displayed on the specific display region. In response to touch on a desired key in the specific display region, the control section determines that an input of the key has been performed.
