Input and output device of input and output system connected to e.g. patient monitor for medical treatment execution system, has user-side surface having spatial distinct structure relative to planar surrounding area in control region

摘要

The device (10) has a proximity and touch-sensitive input and output unit (30) having a user-side surface (11a) provided with a display area (13) to display the visual information. The display area comprises a control region (12) to display and change position of a character (15) of outputs by touching user-side surface at respective position of character and movement gesture. The user-side surface is formed with spatial distinct structure (100) in relation to a planar surrounding area (11b) in control region, to indicate haptic detectable positioning region of character. Independent claims are included for the following: (1) input and output system; and (2) medical treatment execution system.
