An image capturing device may be combined with a touch screen to generate a tactile map of an environment. The image capturing device captures an image of the environment which is then processed and used to correlate a point of user contact on a touch screen to a particular tactile sensation. The touch screen may then generate an electric signal (i.e., tactile feedback) corresponding to the tactile sensation which is felt by a user contacting the touch screen. By using the electrical signal as tactile feedback (e.g., electrovibration), the user may determine relative spatial locations of the objects in the environment, the objects' physical characteristics, the distance from the objects to the image capturing device, and the like.

A method and an apparatus for laser marking indicia in the volume of gemstones such as diamonds, the indicia being made up of a plurality of microscopic dot-shaped marks whose build-up can be initiated by exposing naturally-occurring internal defects or impurities in the volume of a gemstone to a tightly focused train of laser pulses. Authentication data is encoded in the gemstone from the relative spatial arrangement of the dot-shaped marks that form the indicium. Taking advantage of the presence of otherwise invisible defects in the gemstone allows for inscribing indicia with laser pulses carrying energies substantially lower than the threshold energy required for inscribing in the volume of a perfect gemstone material. The marking process is then much less susceptible to inflict damages to the surface of the gemstone, and the marking can be performed using a broad variety of femtosecond laser systems. The dot-shaped marks engraved at a depth below the surface of a gemstone can be made undetectable with the unaided eye or with a loupe by limiting their individual size to a few micrometers, while devising indicia made up of only a few marks. As a result, the marking does not detract from the appearance and value of the gemstone. The procedure for laser marking accounts for the random spatial distribution of the defects present in natural gemstones as well as for their strongly localized character. The presence of an indicium can be detected by using a dedicated optical reader that can be afforded by every jewellery store.
