Knobs are ubiquitous in technology user interfaces, but touchscreens are increasingly replacing them for interface controls. The latest project from [upir] combines a rotating knob with a touchscreen ...
Abstract: This paper proposes an absolute positioning method for distance encoding by fusing reference signals with incremental signals. Reference marks with extinction characteristics are embedded in ...
Abstract: This paper presents a monolithic optical encoder using CMOS image sensor (CIS) with background light cancellation. Both the absolute and incremental encoders are designed and fabricated on ...
