The table presents a selection of research articles on experimental auditory localization and the pointing methods used. The selected articles propose a comparison of different pointing methods or provide information about a specific method. The Pointing method column provides the used or analyzed pointing methods [Head (H), Gaze (G), Hand/Finger (F), Hand Pointer Tool (T), Other (specified)]. The Spatial dimension column indicates which spatial dimensions are considered [azimuth (A), elevation (E), distance (D)]. The parentheses indicate that the variable is a part of the assessment, even though it is not the main object of the research. The Auditory cue column indicates whether the focus of the article is on the analysis of a specific auditory cue: ITD, ILD, HRTF. The Environ. column indicates whether the test was conducted in a real environment (R), using loudspeakers placed in real space around the listener, or in a virtual environment (V), with the listener wearing audio headphones and using HRTF techniques. “Graph_Int” for Graphical Interface. “PB” for Push Button. (a) Gun pointer. (b) Hand-held marker. (c) Schematic 2D and 3D views on which the subject reported his localization judgment with a mouse or a joystick. (d) Representative scale with hand selection. (e) HRTF measurement. (f2) Two-alternative forced choice. (f3) Three-alternative forced choice. (f4) Fifteen-alternative forces choice. (g) Listener had to walk to the location perceived as the source. (h) On a computer terminal with a numeric keypad. (i) Listener was instructed to “point with her/his nose.”
