Computer monitors are permanently increasing in size and pixel density over the last decades. Large displays are affordable now, for daily purposes. Through this technical improvements offices will be provided with large displays and even display walls in the future. These displays improve the effectiveness when working with huge amounts of data or many applications simultaneously. Common input devices downgrade the improvements involved in these displays. To work more efficient a certain distance to the display wall is needed which is disrupted by touch input. Another problem that is tackled in this work, is the search for the mouse cursor which users lose on the large high-resolution displays. It also is exhausting to move the cursor over the display wall with its vast expanse. Huge data sets and many simultaneously opened applications need to be arranged so users can keep the overview. To make this possible with distance to the display wall, I elicit and evaluate a mid-air gesture set for window management on large high-resolution displays in this work through an participatory approach. Each, the elicitation and evaluation of the gesture set is performed by user studies. Further, for the elicitation study, methods are applied to reduce the influence of prior experiences of the users. These methods are investigated within the study to determine their effect on legacy bias reduction. The outcome of the evaluation of the gesture set shows that ordinary users of computer systems are good designers for mid-air gestures. Although the received gesture set cannot compete with the mouse, the study participants liked it and it solved the issue of the lost mouse cursor.
