Abstract: A method and system for providing a cooking support service. A computer-implemented method may include receiving a selection on a specific recipe from a user of an electronic device among recipes registered on a platform; and providing specifications information about each piece of cookware included in the specific recipe.

Abstract: A method of providing a game based on augmented reality includes: performing, at an augmented map server, three-dimensional (3D) modeling based on object information about a reality object in response to extracting a location of the reality object from a map provided from a map server; mapping, at the augmented map server, an augmented reality object based on a location of the reality object in response to creating an augmented map according to performing of the 3D modeling; determining a location of a client based on beacon information of at least one Internet of Things (IoT) device configured as a beacon; and providing an augmented reality game environment by disposing the reality object on the augmented map based on the location of the client.

Abstract: A method and system for adjusting focusing length to enhance vision of a user. A method for adjusting focusing length includes controlling an object to be displayed and adjusting a focusing length indicating distance to a lens from a virtual surface where eyes of user are located by changing at least one optical property of then lens based on vision setting information while an object is displayed.

Abstract: A method of providing a card game implemented by a computer includes the steps of; determining open cards and hidden cards different from one another to be assigned to first and second user terminals each including a screen configured to display an open card area having rows and columns and a hidden card area; providing a first card identifier information of the open cards, a first location information of the open cards, a second card identifier information of the hidden cards, and a second location information of the hidden cards; determining a rating of cards disposed along each column of the open card area based on a combination of the cards in the same column; comparing the rating of each column of the first user terminal to that of the second user terminal; and determining win or lose of the card game based on the compared result for each column.

Abstract: A method of processing, at a web server, a long-polling between a client and a service server configured to provision a service to the client over a network includes: receiving, at the web server, a poll request from the client; transmitting, via the web server, the poll request to the service server; receiving, at the web server, a poll reply to the poll request from the service server; generating, at the web server, webpage data based on the data in the poll reply; and transmitting, via the web server, the webpage data to the client as the poll reply. The poll reply received at the web server includes data to be applied in association with the client.

Abstract: A method of providing an overlay display control performed on an electronic device, the method including: displaying a progress screen of a main service associated with an application through a first virtual layer under control of the application executed on the electronic device; displaying a user interface on a preset area of the first virtual layer, the user interface configured to receive a selection signal on a control function associated with the main service; displaying a second virtual layer for providing an additional service associated with the main service overlapping the first virtual layer in response to a progress of the main service meeting a preset condition; and processing a progress of the additional service, including: hooking a selection signal input on a partial area of the second virtual layer; and calling a control function corresponding to the partial area of the second virtual layer.

Abstract: Provided is a game service method and system. The game service method may include providing a game service to terminals of game users over a network; setting rankings of the game users based on progress results of the game service; storing and managing a game log of a previous game played by a first game user of a predetermined ranking or greater in association with the first game user; and providing a replay service to replay the previous game played by the first game user on a terminal of a second game user based on the game log stored in association with the first game user, in response to a request from the terminal of the second game user.
