Abstract

A method for operating an electric motor-driven food processor for preparing a preparation item, wherein is prepared in one or more sequential preparation steps. A user of the food processor receives information from the food processor about an operating parameter for the food processor and/or a preparation parameter for the preparation item and/or transmits said information to the food processor. In order to make using the food processor especially comfortable for a user, the information is projected into the visual field of the user by a wearable image generating device configured separately from the food processor, in particular an eyeglass-type construction worn in front of an eye while the user is looking at the food processor in a defined angular range, wherein the information is superimposed onto the visual field.

First claim

What is claimed is:

1. An electrically driven food processor comprising:
a preparation vessel,
a mixer and/or heating element allocated to the preparation vessel, and a communication device configured for transmitting information about an operating parameter for the food processor and/or a preparation parameter for a preparation item to a user of the food processor,
wherein the communication device exhibits a projection surface with a touch sensor for displaying information, and wherein the communication device has at least one marking element configured for determining a spatial orientation of the food processor relative to an external image generating device, the marking element exhibiting a grid of a plurality of two- or three-dimensional partial marking elements situated uniformly one next to the other, wherein the partial marking elements are actively luminous points and become smaller in a preferred direction of the marking element.

2. The food processor according to claim 1 , wherein the communication device exhibits several marking elements spaced apart by a distance.

3. The food processor according to claim 1 , wherein the communication device comprises a projector allocated to an eye of the user of the food processor.

4. A system comprised of a food processor and a wearable image generating device that is designed in the form of a pair of glasses and is formed separately from the food processor, wherein the wearable image generating device comprises a projector for projecting information into a visual field of the user, and wherein the food processor comprises a preparation vessel, a mixer and/or heating element allocated to the preparation vessel, and a communication device for communicating with a user of the food processor and/or with the image generating device,
wherein the communication device exhibits a projection surface for displaying information that relates to an operating parameter for the food processor and/or a preparation parameter for a preparation item, and is projected by the image generating device.

5. The system according to claim 4 , wherein the food processor has at least one marking element for spatially orienting the image generating device relative to the projection surface, wherein the image generating device has a detection device for detecting the marking element, an evaluation and control device for determining the orientation of the image generating device relative to the marking element, and a light source for optically emitting the information.
