If you've experienced Leap Motion, you'll certainly remember it with its gesture recognition technology. This kind of gameplay that restores both hands in virtual reality brings us a unique interactive experience. However, due to lack of recognition accuracy, Leap Motion occasionally has minor problems such as gesture drift and interruption. Leap Motion also realized this deficiency, and recently announced an engine called the Interaction Engine (beta) to improve this problem.
It is understood that Interaction Engine is an add-on program for the well-known game engine Unity, so it will support all VR devices. It fixes the default system physics rules and makes gesture recognition more natural and smooth. For example, when you need to stack blocks in virtual reality, the blocks are likely to bounce off each other, even though your hands hold squares. However, when the Interaction Engine is turned on, the manipulation becomes more accurate. You can feel the difference through the following two comparison charts.

However, Leap Motion also said that Interaction Engine is not suitable for those smaller and slender objects. It is hoped that Leap Motion will be able to solve this problem in the future. In general, Leap Motion is one of the best gesture recognition tools available today. If it can be integrated into VR headlines, it may give us a more complete VR experience.
Anisotropic magnets are magnets whose magnetization directions in the magnets are aligned in a certain direction.
Magnet powder for anisotropic magnets is composed of a single crystal or polycrystal with an aligned direction of magnetization in one magnet particle. When a magnetic field is applied externally during molding (this magnetic field is called an aligning magnetic field), the magnet powder moves to align with the direction of the magnetic field and is solidified in an aligned state, resulting in an anisotropic magnet. Magnet powder aligned with an aligning magnetic field is solidified with keeping magnetization. Therefore, after removing the alignment magnetic field, the molded body becomes a magnet having a magnetic force.
