• What is the KAT WALK?
  • The KAT WALK is KAT VR’s flagship product and the final result of several years of careful research and design. Simply put, it is a VR Omni-directional Treadmill (ODT) that offers a definitive and elegant solution to the challenge of achieving infinite motion on a virtual space without any of the disadvantages found in traditional controller-based locomotion systems. Thanks to its ergonomic design and its highly intuitive mode of interaction, the KAT WALK solves three fundamental problems that have been an obstacle for VR content: motion sickness, space limitations and safety concerns. The KAT WALK offers an innovative answer to these issues and opens unlimited possibilities for the development of new and exciting VR experiences. The KAT WALK is a device that has the potential to change how we interact with the virtual world.

  • What exactly is a VR ODT and what makes it different from other available VR products?
  • An ODT (Omni-directional Treadmill) is a device that allows the user to perform locomotive motion in any direction, allowing for 360 degrees of movement. When applied to VR games and other interactive digital content, these devices allow for the creation of a limitless space in which the user can move safely and freely. An ODT isn’t actually a treadmill with a conveyor belt like those you can find in gyms and their mechanics are a little bit complex, but they are easy to use and represent a very clever solution to the space limitations of VR.

  • What makes the KAT WALK special?
  • The KAT WALK’s unique design, optimized for freedom of movement, is what makes it stand out among other similar products on the market. First of all KAT VR has developed a state of the art motion tracking algorithm for its sensor system that allows for almost zero delay and therefore lets the user enjoy a very precise motion tracking effect that translates into smooth, reliable movement into the virtual world. Similar devices also have serious design limitations such as rings or other rigid barriers around the waist of the user that can limit the range of movement and also pose serious safety hazards. Other ODTs also suffer from an over-reliance on straps, harnesses and other modes of restraint for the extremities and the torso, while the the KAT WALK only requires a single harness for the waist and lets the arms and legs of the user completely free. The KAT WALK also avoids the problem of cable entanglement through the careful integration of the headset connections into the body of the device. With the KAT WALK you are absolutely free to move in the virtual world while being completely safe.

  • What is the difference between the KAT WALK and the KAT WALK Premium?
  • Both the KAT WALK and the KAT WALK Premium offer essentially the same immersive VR experience and both of them have the same base technology. The KAT WALK Premium is sturdier than the standard KAT WALK and has a strong protective shell for the support pillar, while the standard KAT WALK is lighter and easier to transport. Although both products are meant to be used commercially, the standard KAT WALK is also directed towards consumers. Both devices have the same content available and a are covered by the same warranty and terms of use.

  • Are there any health restrictions to using the KAT WALK?
  • It is recommended that that pregnant women, the elderly, those with visual disorder or a record of mental illness or those once affected by other serious health conditions such as heart diseases refrain from using the device.

    Since different people have different constitutions, we advise not to use the product for a long time in case of experiencing any discomfort, such as giddiness, dizziness, headache, etc. If you have any discomfort, please stop using it immediately and stop any high attention demanding activities (such as driving) until the symptoms completely disappear.

  • Any precautions to take regarding the product's position?
  • Each time you need to dismount the rig. Lock the device at the pedal position, then turn it off.

  • What is the mini's noise level?
  • When the product is currently used, the noise is approximately 40-50 decibels, the equivalent of soft conversation between people. The chassis is built with sound-absorbent material. The product is still under optimization, so we seek to further decrease this sound output.

  • With what ease can I perform actions like walking and steering?
  • When “walking” on the curved base’s surface, it distributes force applied by the human foot into the vertical component of the force in the direction of the extensional arc surface. With the low friction surface, it is possible to achieve a natural sliding motion of the foot. The combination of the two simulates the feeling of natural movement.

    The back rod and sitting part of the device use a high-strength, low-density lightweight material to minimize the weight of the protective structure while keeping you safely strapped in and supported.

  • Does it support real-time input of hand movements?
  • The controllers decide if it is supported. Oculus, Vive, and other products all support real-time input of hand gestures. Our sensors only detect the movement of your feet.
