Abstract: Distance-based framing includes obtaining at least a video stream during an online conference session. The video stream, an audio stream received with the video stream, or both the video stream and the audio stream are analyzed and a framing that either focuses on a speaker in the video stream or provides an overview of participants in the video stream, the framing being is composed based on the analyzing. A potential error in the framing is detected based on further analysis of at least one of the video stream, the audio stream, or distance sensor data received with the video stream. If the distance sensor data contradicts the potential error, the framing is maintained, but if the distance sensor data confirms the potential error, a new framing is generated.

A potential error in the framing is detected based on further analysis of at least one of the video stream, the audio stream, or distance sensor data received with the video stream. The potential error may be contradicted or confirmed based on an amount of motion when the framing focuses on the speaker. If the distance sensor data contradicts the potential error, the framing is maintained, but if the distance sensor data confirms the potential error, a new framing is generated.

Abstract: Method and apparatus (16) for projecting infrared or near infrared or low intensity visible light from a pen, pointer or other guiding object in the form of a coded pattern image, detectable by a camera and recognition system but invisible, or hardly visible to the user and audience, thus controlling and interacting with a computer (19) during a presentation, computer supported work and/or other interactive use of a computer, including pointing, selecting, drawing and writing, both distantly (11) and closely (10) to the front or rear projection screen or possible other type of display screen, without any distracting visual patterns or spots, while the possible visual feedback to the user and audience can be generated by the computer and display system onto the display screen in a controlled and context-sensitive way.
