Tablets with the screen size of 5 inches are more suitable for displaying images for the two eyes. Popular screen sizes of tablets are 7-10 inches.

  • 3D sound is properly calculated volumetric sound fed into stereo headphones. This sound enables user to locate a sound source in virtual space i.e. to discern intuitively the location of a sound source.
  • Sound engine has to calculate sound levels from a sound source located at a certain point of virtual space model on the grounds of the source directivity when it is reasonable, coordinates and orientation of the user's head in that space.
  • Information about head orientation and position should be used in a way ensuring sound levels dependability from distance to the sound source, appropriate delay of sound entering each ear, taking into account ear shadowing due to head orientation when the ear is not at the line directed to the sound source, diffraction of sound and its spectrum as well. Sounds of various frequencies are shadowed by head in different ways and differently perceived due to auricle curvature.
  • the method used to binaural sound delivering to the user includes modification of original sound for each user's ear, implementation of relevant calculations for the sound to be properly delivered to each ear with different volume levels, calculated time delay of sound wave front, implementation of sound filters for various sound pitches in order to ensure natural perception of the sound and opportunity of its source localization in the virtual space.
  • the distance to the sound source depends on user's head location and orientation in relation to the source of a sound. E.g., the nearer is the sound source located to the ear the louder is the sound. The greater is the difference in distance from the sound source to each ear the greater is the delay of sound wave front entering the farther ear.
  • the loudness of a sound depends not only on the distance to the sound source it is additionally decreased in case the sound source is shadowed by a head and it should also be used to properly calculate sound levels for each ear individually. And the effect of shadowing is not the same for different sound frequencies at that.
  • the method ensures an opportunity of creation games based solely on sounds or the ones where visualization is not used from time to time. It will be possible to play on the basis of aural reception. Hearing a sound user can localize its source and take appropriate actions depending on the application objectives e.g. approach nearer to the source or retreat from it or shoot at it.
  • the figure illustrates user's head and difference in distances to the ears.
  • the average distance between human ears equals to 6 inches.
  • Time delay and volume of a sound are two components of binaural hearing that have been not comprehensively implemented yet in soft and hardware. Time delay has not been implemented in direct sound and other software applications while volume of a sound is partially implemented in some sound engines and libraries. Nevertheless those features could not be implemented comprehensively without usage of 3D-orientation sensors as neither stereo sound equipment nor even surround gives any opportunities of accurately positioning of sound source at all directions.
  • Sound signals being perceived by the left and the right ear are significantly different due to spatial separation of sound receivers (auricles), shadowing effect of the head and torso and diffraction effects. That makes possible sound source localization within a space to be performed on the grounds of the following three physical factors:
  • intensity factor (Interaural Intensity Difference - I ID) - resulting from difference in intensity levels of sound wave due to diffraction of it around a head and acoustic shadow formation at the side opposite to the sound source.
  • 3d-applications using three-dimensional sound according to the invention could be used in computer games, training applications intended for military and police staff etc.
