VDI/VDE 3850 Blatt 3:2015-11

This standard applies to the touchscreen-specific design of dialogues for technical plants in industrial use. The design recommendations given in this standard focus on touchscreen use with fingers. A touchscreen-based user interface designed for interaction by means of the finger will mostly also be suitable for use with other contact elements such as a stylus, gloves, amputation appliances. The standard provides rules and recommendations with respect to the design of stationary touchscreens. The recommendations given here include fundamental rules for design (such as the size and labelling of objects), information on the use of dialogue techniques, and examples of touchscreen display designs. This standard, therefore, is offered to the designer of usable user interfaces, assisting him in the design of touchscreen-specific dialogues while leaving enough freedom in the design to allow for customised solutions.
