AN ELECTRONIC DEVICE, A SYSTEM, AND A METHOD FOR CONTROLLING A VICTUAL ORDERING SYSTEM

The present disclosure pertains to the field of Internet of things (loT) and detection devices, and relates to an electronic device and to a method for controlling a victual ordering system.

BACKGROUND

In general, as a non-local guest at a restaurant serving sharing type of food, it can be an overwhelming task to know and decide what to order and what quantities. The responsibility to recommend a suitable set of dishes often falls on the host of the establishment. While tasting menus can be offered by restaurants and designed for specific group sizes, it may be challenging to consider the large variation given by group demographics and/or personal preferences. One challenge lies in recommending a set of dishes that deliver a harmonic taste journey while considering for example the calorific intake and/or personal preferences of both the group and the individuals within. Another challenge lies in aiding restaurants in adhering to national legislation regarding sustainable consumption and food waste.

SUMMARY

Accordingly, there is a need for electronic devices and methods for controlling a victual ordering system, which may mitigate, alleviate, or address the shortcomings existing and may provide the control of a victual ordering system.

An electronic device is provided. The electronic device comprises memory circuitry, processor circuitry, and interface circuitry. The electronic device is configured to obtain, from an optical device, detection data indicative of an item. The electronic device is configured to control, based on the detection data, a victual ordering system.

Further a method performed by an electronic device is disclosed. The method comprises obtaining, from an optical device, detection data indicative of an item. The method comprises controlling, based on the detection data, a victual ordering system.

Further, a system is disclosed herein, the system comprising an electronic device as disclosed herein and one or more electronic devices as disclosed herein. The disclosed electronic device, related method, and system may provide an improved controlling of a victual ordering system.

The disclosed electronic device, related method, and system may provide improved controlling of a victual ordering system, for example by providing menu data indicative of a victual menu. The menu data may comprise sharing menu recommendations. In other words, a victual ordering system may be controlled based on sharing menu recommendations. A sharing menu recommendation may comprise a recommendation for specific group sizes comprising one or more subjects, such as considering personal preferences of the one or more subjects of a group of subjects. A personal preference may comprise a calorific intake with personal preferences. The present disclosure may provide menu data indicative of a sharing menu for a group of subjects, such as a shared menu recommendation for a group of subjects. The menu data may be based on an individual assessment of the subjects (such as guests) considering detection data and/or user input, such as gender, age, additional information on activity level, and personal preference. Further, the present disclosure may improve the controlling of a victual ordering system by facilitating selecting and/or adapting dishes to a subject. For example, it may be appreciated that the controlling of a victual ordering system may comprise to compose a customized taste journey and/or select dishes for a nutritionally balanced meal based on a group of subjects composition and/or based on an individual subject. Further, the present disclosure may provide menu data comprising food recommendations at an individual level, for example obtained via user input by utilizing the knowledge from one or more electronic devices such as fitness bands and/or activity trackers.

It may be appreciated that the present disclosure may provide the possibility to obtain detection data for example to monitor intake continuously and encourage consumption of specific dishes to attain a nutritionally balanced meal. Further, detection data may be used to continuously consider a calorific intake potential of subjects (such as guests) to enable sustainable consumption and avoid food waste. It may be appreciated that the present disclosure may help eating places (such as restaurants) to adhere to national regulations, such as food waste prevention legislation.

Further, the disclosed electronic device, related method and system may improve the logistics of a victual ordering system (such as of an eating place). For example, the present disclosure may improve the efficiency and/or reduce the labor of the employees of an eating place and may save time and money for both subjects (such as guests) and the eating place.

In other words, the electronic devices disclosed herein (such as electronic devices 300A, 300B) may be configured to generate the menu data based on the victual tracking parameter. In other words, the electronic device 300A, 300B may be configured, based on the detection data (such as based on one or more vision sensors), as the one or more subjects at a victual consumption place are eating, to keep track of a consumption of victual items and/or products by the one or more subjects. A victual tracking parameter may be seen as a parameter associated with a consumption of a victual item and/or object, such as a detected consumption of a victual item and/or object (such as detected by the optical device). A victual tracking parameter may be seen as comprising information indicative of one or more of: consumption of a victual item, quantity of the victual item, portion of the victual item, a state of consumption, and a state (such as solid, liquid, hot and/or cold) of the victual item. In one or more example electronic devices, the optical device may dynamically monitor the consumption of a victual item by one or more subjects.

In one or more example electronic devices, the electronic device 300A, 300B may be configured to dynamically suggest (such as by using the victual ordering system, such as by dispatching and/or displaying the menu data, such as updated menu data) a victual item (such as a food item) to one or more subjects, based on the victual tracking parameter, for consumption. For example, staple dishes such as rice, bread, and/or sauce may be timely re-ordered as soon as they are empty. The re-ordering of staple dishes may for example be based on the number subjects that are monitored. For example, when the tracking parameter is based on a tracking of ten subjects, the time period for timely re-reordering may be longer than when the tracking parameter is based on a tracking of two subjects. Optionally, users may need to confirm re-ordering to prevent unnecessary ordering. An advantage of this, may be that it could enable a new type of pricing, for example apportion a cost to uneaten food to show food waste. For example, by having menu data based on the victual tracking parameter, a victual item such as a main dish, a side dish, and/or a dessert may be recommended based on a consumption of previous victual items, such as dishes. This may provide a victual menu comprising a balanced mix and/or a “taste journey” appreciated by the guests (such as subjects).
