| Popis: | PurposeThe paper aims to present the prototype of a graphical touch screen of thermal signs for the blind.Design/methodology/approachThe surface of every Peltier pump is a touch point that demands the thermal stabilization. Miniature Peltier modules can work both as heat and cold generators. They are also able to measure the required dot temperature. Graphical screen of thermal signs displays a simple symbol or Brail text. Special computer program was made to control this innovative device. The software enables monitoring the temperature of each Peltier module.FindingsThe experiments carried out with blind people show that they are able to recognize hot and cold dots. Infrared photos of the device have been made using the thermographic MK525 camera.Originality/valueThe paper illustrates that it is possible to display simple graphics by using Peltier micropumps. |
