“…Several studies have investigated how the characteristics of visual interfaces, such as the position of heads-up displays on the screen e.g., [20,21], 3D stereoscopy e.g., [22], screen size e.g., [23], or the point of view e.g., [24,25], influence players' performance, players' experience, or both. The results are potentially interesting for designers who may better control the challenge presented by games by adjusting the parameters of the visual displays.…”
