A play system, comprising: one or more toys comprising one or more electrically conductive parts, the one or more conductive parts defining a spatial pattern, the one or more toys having a physical configuration that is modifiable by a user, the spatial pattern being dependent on the physical configuration of the one or more toys, the one or more toys including a first toy; a magnetic field generating device arranged to generate a magnetic field for inducing an eddy current in one or more of the electrically conductive parts; a sensor configured to detect the induced eddy current; and a data processor; wherein the first toy and at least one of the magnetic field generating device and the sensor are movable relative to each other; wherein the sensor is configured to detect the induced eddy current during relative movement between the first toy and at least one of the magnetic field generating device and the sensor, and wherein the data processor is configured to: receive sensor data from the sensor, the sensor data being indicative of the eddy current detected during relative movement between the first toy and at least one of the magnetic field generating device and the sensor, detect the spatial pattern of the electrically conductive parts based at least in part on the received sensor data, determine the physical configuration of the one or more toys based on the detected spatial pattern.

A smart block can include a plurality of displays and configurable magnet components to selectively attract or repel other smart blocks. The smart block can include proximity sensors to identify a surface of another smart block close to the smart block to determine if the smart blocks are correctly oriented based on an application or game associated with the operation of the smart blocks. A plurality of smart blocks can be configured to display a portion of a picture (as a puzzle), such that when the smart blocks are oriented correctly they collectively display the complete picture. The smart blocks can be used in conjunction with a smart mat that is configured to move the smart blocks in response to commands received from a remote computing device. The smart blocks and the smart mat can facilitate interactivity with other, remote users, such as between a caregiver and a child.

An electronic toy comprising: a sensor for detecting movement of the electronic toy; a reader for detecting markers in a proximity of the electronic toy; a user-interface for providing a user-perceptible output; a processing unit configured to control the user-interface responsive to a detected movement and a detected marker.

A toy brick system is provided having a plurality of bricks each of which has a post extending from first end of a body of the brick and having a socket at a second end. The post in each brick in the plurality is engageable with a socket of an adjacently place brick in a removable rotational engagement enabling curved and angled configuration of assembled structures. Engagement and disengagement from the rotational engagement can only occur at a specific engagement angle between adjacent bricks thereby maintaining the rotational engagement of adjacent bricks once engaged and rotated out of the engagement angle. The bricks are configurable in a linear fashion or with curved exterior walls for forming curved structures.

The plastic toy building block is provided with electrical contacts to determine its position. The block has a basic body having recesses extending from top to bottom in its interior. In these are each inserted, combined into packets, several discrete elastically resilient conductor wires clamped between plastic strips. Elastically resilient conductor wires protrude downward into the recess. Contact points protrude from the plastic strips at the top. Several electrical cables are led from each nub to the underside of a nub plate to discrete contact points. Except for the nub surfaces, the nub plate can be covered by a cover plate and hereafter can be placed with the nub plate on the basic body of the toy building block. The lower contact points on the film then make electrical contact with the upper stubs and thus with contact points of the conductor wires.

A construction toy is disclosed. The construction toy comprises at least one prismatic or cylindrical housing with a closed end and an open end, with two or more connection means located on an external surface between the open end and closed end. The construction toy may further comprise an ornamental component, stickers, a motion activated illumination arrangement resulting in numerous modes of play of the construction toy. Multiple housings of the construction toy act as building blocks. The construction toy acts as a means to collect, display and store numerous ornamental components. The construction toy can be customised with stickers which can be revealed and hidden using a motion activated illumination arrangement comprising an infrared sensor and UV light.

A transformable modular toy element is provided. The transformable modular toy element is for use in a toy construction system comprising a plurality of modular toy elements. The transformable modular toy element comprises a body portion and a head portion. The body portion comprises one or more coupling members, the one or more coupling members being adapted for releasably coupling the body portion with modular toy elements of the toy construction system. The head portion is attached to the body portion. The head portion comprises a cavity for receiving the body portion therein. The body portion is moveable with respect to the head portion between a retracted position where the body portion is retracted into the cavity, whereby the transformable modular toy element has a first shape, and a deployed position where the body portion is in the axial direction deployed from the cavity, whereby the transformable modular toy element has a second shape. The transformable modular toy element further comprises first locking means adapted to lock the body portion in the deployed position.

A toy atomization device construction elements decoration comprises a base 1. An opening water tank 2 is integrated into the humidifier base 1. A water inlet 8 is opening on the upper surface of the casing 111. The inside of the base 1 is combined with the water tank 2 and an atomizing chamber 3.

An interconnectable construction element has a body section, a first socket coupled to a first end of the body section, and a magnetic ball. The first socket has a recess in communication with an opening. The opening extends from a first lateral side of the first socket at least to a distal end thereof. The magnetic ball is individually rotatably receivable into the recess of the first socket for forming a magnetic connection with another interconnectable construction element having another magnetic ball.
