The exhaust hood (1) of the present invention comprises a body (2) that is positioned above the cooker (O) such that there is a distance between the cooker (O) and the body (2), a projector (3) that is disposed on the body (2) and that can project onto the cooker (O) and/or the countertop (T), a sensor (4) that is disposed on the body (2) and that can detect the movement in the area scanned, a virtual keyboard (5) that is projected by the projector (3), and a control unit (6) that is disposed on the body (2) and that performs operations by means of the virtual keyboard (5) (Figure 1, Figure 2).
In the exhaust hood (1) of the present invention, the virtual keyboard (5) is projected onto the countertop (T) surrounding the cooker (O) and whereon the cooker (O) is seated so as to be in the vicinity of the cooker (O) and extend from the cooker (O) towards the user and the position of the virtual keyboard (5) around the cooker (O) is changed by the control unit (6) depending on the command of the user.
The control unit (6) disposed on the body (2) generates a depth map by means of the sensor (4) and the said depth map is transmitted to the processor module (PC) used in the control unit (6) and in the said processor module (PC) it is followed by defining the human hand by using the algorithm determined by the manufacturer. The finger and hand movements are detected by the sensor (4) and converted into vectorial data by the control unit (6) and the household appliances that communicate with one another by wireless communication are controlled by the control unit (6) by means of the said vectorial data.
The user controls the control unit (6) via the virtual keyboard (5) that is projected onto the countertop (T) by means of the projector (3). The virtual keyboard (5) is projected into an area that is predetermined by the manufacturer. The virtual keyboard (5) being projected to an area close to the cooker (O) and to different areas in the vicinity of the cooker (O) depending on the preference of the user increases the utilization effectiveness of the countertop (T). By means of the virtual keyboard (5), the exhaust hood (1) and/or at least one household appliance that communicates wirelessly with the exhaust hood (1) is controlled.
In an embodiment of the present invention, the virtual keyboard (5) comprises a figure (7) that enables the virtual keyboard (5) to be slid to the desired position around the cooker (O) by being pressed on. The sensor (4) that detects that the figure (7) is pressed on, transmits the sliding movement made by the user without lifting off the finger on the figure (7) to the control unit (6), that in turn changes the said movement to vectorial data and the control unit (6) enables the projector (3) to move the virtual keyboard (5) in the direction of the finger movement depending on the vectorial data (Figure 3).
In a derivative of this embodiment, after the figure (7) is pressed on by the user and pushed, the virtual keyboard (5) is positioned at the location it is pushed to. In the case the figure (7) is pressed on for the limit time period (∆t) predetermined by the manufacturer, and the figure (7) is sent to a direction with the finger and the user lifts off the finger from the figure (7), the control unit (6) moves the virtual keyboard (5) to a position located in the direction of the said finger (Figure 3).
