Abstract
Self-mixing interferometry (SMI) sensors can be used for generation of content using an input device without requiring a touch-sensitive surface. In some examples, the SMI sensors can be used to detect characteristics of the input device including position, orientation, and/or motion of the input device and/or force applied by the input device (e.g., force applied by a stylus tip). In some examples, some or all of the characteristics of the input device can be used in processing to generate content, including textual character input and three-dimensional objects. In some examples, the generation of content can use information from one or more additional sensors for the input device and/or from additional devices in combination with the characteristics of the input device based on the SMI sensors for generation of content.
