The picture you look at with the mini-hand-videocamera will be projected in realtime. That means 24 pictures per second are shown on the tactile display “TIM”. The functions of the three buttons above the tactile display are to zoom in or out, choose the right contrast or to invertate. With the hand on top of the VideoTIM device you can adjust your individual bightness - this makes e.g. letters bigger or smaller.. |

The user puts one hand on the VideoTIM-display. He can change between active and passive recognition. Active recognition means moving the hand over the tactile dots and the fingercups recognice the details. The picture appears as a relief. The passive recognition uses the TPS - the Tactile Projection System by ABTIM. The soft knocking dots stimulate pictures onto the skin of the fingers. |
