Input device for a medical treatment system

An input device comprising:

• a control unit configured to:
• interpret touch input data received from a display screen of the input device, the touch input data based on detection of touch on a surface of the display screen;
• and
• transmit elements of control data to the display screen, the elements of control data respectively capable of representing
• one or more graphemes of a first language and
• one or more graphemes of a second language;
• and
• the display screen configured to receive elements of control data and, based on the elements of control data:
• display a plurality of touch buttons that are configured to receive haptic input from a user, at least some of the touch buttons each representing a grapheme, wherein, in a first state, a first set of touch buttons each displays a grapheme of a first language, and wherein, in a second state, a second set of touch buttons each displays a grapheme of a second language;
• display a language swap touch button that is configured to receive haptic input from the user, wherein i) in the first state, the language swap touch button displays a phrase indicating the second language to be applied to at least some of the touch buttons, and ii) in the second state, the language swap touch button displays a phrase indicating the first language to be applied to the at least some of the touch buttons;
• toggle between displaying i) the first set of touch buttons, and ii) the second set of touch buttons in response to the user providing the haptic input to the language swap touch button;
• and
• generate the touch input data based on the detection of touch on the surface of the display screen,
• wherein a first haptic input provided to the language swap touch button causes the language swap touch button to switch from displaying the phrase indicating the second language to displaying the phrase indicating the first language and causes the toggling of the input device from displaying the first set of touch buttons to displaying the second set of touch buttons, and a second haptic input provided to the language swap touch button causes the language swap touch button to switch from displaying the phrase indicating the first language to displaying the phrase indicating the second language and causes the toggling of the input device from displaying the second set of touch buttons to displaying the first set of touch buttons.

• display a plurality of touch buttons that are configured to receive haptic input from a user, at least some of the touch buttons each representing a grapheme, wherein, in a first state, a first set of touch buttons each displays a grapheme of a first language, and wherein, in a second state, a second set of touch buttons each displays a grapheme of a second language;
• and
• generate touch input data based on detection of touch on a surface of the display screen;
• and
• a control unit configured to:
• interpret the touch input data received from the display screen;
• and
• transmit the control data to the display screen, the control data representing:
• a language swap function,
• one or more graphemes of a first language, and
• one or more graphemes of a second language;
• wherein:
• the language swap function is controlled by a language swap touch button that is configured to receive haptic input from the user, wherein i) in the first state, the language swap touch button displays a phrase indicating the second language to be applied to at least some of the touch buttons, and ii) in the second state, the language swap touch button displays a phrase indicating the first language to be applied to the at least some of the touch buttons;
• and
• the display screen is configured to toggle between displaying i) the first set of touch buttons, and ii) the second set of touch buttons in response to the user providing the haptic input to the language swap function,
• wherein a first haptic input provided to the language swap touch button causes the language swap touch button to switch from displaying the phrase indicating the second language to displaying the phrase indicating the first language and causes the toggling of the input device from displaying the first set of touch buttons to displaying the second set of touch buttons, and a second haptic input provided to the language swap touch button causes the language swap touch button to switch from displaying the phrase indicating the first language to displaying the phrase indicating the second language and causes the toggling of the input device from displaying the second set of touch buttons to displaying the first set of touch buttons.
