The present invention relates to a unit block having a coupling portion and an insertion portion provided in special structure and shape such that, instead of providing an assembly-type toy that makes a user build an assembly-type completed product according to the manual, the user is enabled to implement various articles by exercising creativity without feeling bored. The present invention provides a unit block, which has integrally provided coupling and insertion portions, and provides, as a means for using the same when a desired object is to be implemented, a unit block coupling means comprising: a unit block coupling portion, which has an insertion portion sized to be fitted into the coupling portion and narrowed by a degree corresponding to the outer wall of the coupling portion at the upper end of the coupling portion, thereby being integrated therewith, wherein circular penetration/coupling holes are formed on fourth side surfaces of the insertion portion, and partial tube extension portions are formed on the upper/lower/left/right sides of the penetration/coupling holes; the unit block is structured to have a -shaped inner extension concave groove at the center of the surface of the coupling portion; when vertically coupled to a different unit block, a -shaped support piece is fitted and coupled to the -shaped inner extension concave groove formed on the surface of the coupling portion; when horizontally coupled to a different unit block, partial protrusion portions, which are formed on the surface of a support shaft, are fitted to the partial tube extension portions formed in the penetration/coupling holes of the coupling portion; and the unit block coupling means is applied to secure a high degree of coupling force.

There is provided a system for providing interactivity to a guest of an experiential venue, based on sensor measurement of the guest. The system comprises a sensor configured to sense a guest variable of the guest, where the sensor may be a biometric sensor, a facial recognition sensor, a voice stress analysis sensor, a gesture recognition sensor, a motion tracking sensor, or an eye tracking sensor, and may sense heart rate or another guest variable. The system also comprises a control system, which may be implemented as a computer, in communication with the sensor. The control system is configured to determine a guest state from the guest variable, and to modify a venue variable, for example by selecting a path a theme park ride follows. The control system modifies the venue variable according to the guest state to provide increased satisfaction to the guest of the experiential venue.
