Non-linear forces are simulated by a dual-rate spring apparatus, which may also be used to impose nonlinear forces. The apparatus includes a carriage and at least two springs arranged sequentially in series with one another. The spring constant is changed by initially allowing both of the springs to compress to a point and, thereafter, after one spring is generally completely compressed, allowing only the other spring to compress further.

The disclosure is directed to simulating forces using holographic objects. A method according to embodiments includes: generating an invisible holographic object, the invisible holographic object providing a haptic effect; displaying a visible holographic object; aligning the visible holographic object and the invisible holographic object to provide a visible and touchable combined holographic object, the combined holographic object providing the haptic effect; applying a force to the combined holographic object, the applied force causing a displacement of the combined holographic object and including an amplitude and direction; and adjusting the haptic effect of the combined holographic object to generate an adjusted haptic effect representative of an effect of the applied force on the combined holographic object.

The present invention relates generally to a system and method that bring together the advantages of computer games and the physical world to increase engagement, collaboration and learning. The system and method can be used with a myriad of physical setups and can be used for many different content areas in education. In one embodiment, a mixed reality interaction is facilitated with an EarthShake game presented on a display. The game is synchronized with a tangible interface comprising a physical object and a sensor capable of detecting a change in the condition of the physical object. The system and method help kids discover scientific and other learning principles while experimenting with real objects in a physical environment supported with audio and visual feedback. Students interactively make predictions, see results, grapple with disconfirming evidence and formulate explanations in forms of general principles.

The present invention is system and method for demonstrating different principles of physics by modifying the design of the original Newton's cradle, wherein the new device may include multiple levels of spheres, spheres that are hanging from suspension fibers of different lengths, spheres that are disposed in an arrangement wherein spheres are not limited to a single linear array but include spheres that are disposed such that arrays of spheres may intersect each other, and spheres that may be used in any of the configurations but may vary in diameter and mass.
