| 摘要 |
<p>The invention relates to a device for tactual presentation of information, comprising: - a liquid (3) or a gel; - a tactile layer (4) arranged adjacent the liquid (3) or gel; - an arrangement (5) for selectively deforming a surface (31) of the liquid (3) or the gel, wherein - the tactile layer (4) is arranged in such a way that a deformation (311) of the liquid (3) or gel surface causes a deformation (41) of the tactile layer (4) such that by selectively deforming the surface (31 ) of the liquid (3) or gel a tactual presentation of information can be generated in the tactile layer (4), and - the arrangement (5) for deforming the surface (31) of the liquid (3) or gel comprises at least one transmitter (51, 51a, 51 b) for generating acoustic waves (AW) in the liquid (3) or gel which travel towards the surface (31) of the liquid (3) or gel, thereby causing the deformation (311) of the surface (31).</p> |
