Benefits of technology

The technical effect of this patented technology is that it allows keys with smaller sizes but still being able to work properly on screens like shutters without causing damage or affecting their appearance.

Problems solved by technology

The technical problem addressed in this patented technology relates to improving how users can interact with an electronics system through visual displays that include tactile buttons instead of physical switches. Blind individuals may lack their eyesight but still use these touch-sensitive surfaces like virtual keyboard interfaces (VUIs) due to limitations imposed upon usability factors. This makes it difficult for visually challenged/blinding individuals to remember what specific functions were assigned when pressing certain button(s). Even if we don't require accessibility features like VUls, there could also be issues where older men who didn’t wear glasses had difficulty typing braille words correctly.

Embodiment Construction

[0017] With reference to the figures, these show a keyboard 1 for blind people comprising a body 2 carrying a plurality of keys 3 and interface means 4a, b, c, d, e for its connection to an external unit like a PC or the like.

[0018] The keys 3 have a number of portions 7 each having associated a function of the key and having represented such a function in Braille characters thereon; such a function is for exemple a letter to be shown on a display.

[0019] Moreover, the keys 3 are jerky rotatable connected to the body 2 (see arrow F1) so as to select one of the portions 7 of the key 3; such a selected portion is the one completely directed towards the outer of the body 2.

[0020] The keys 3 are also pressable (see arrow F2) in order to activate that function associated to the selected portion, so that each function is selected through rotations (F1) and subsequent pressure (F2) of the corresponding key portion.

[0021] The keys 3 present polygonal form and, preferably, it has a parallele
