Motion sickness is reduced for users of mechanical systems used to practice sports that comprise an immersive virtual reality device. In particular, the use of prediction and interpolation algorithms enable fluid movements to be displayed within the virtual environment.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

A simulation system includes a processor including hardware. The processor performs a moving body process of performing a process of moving a moving body corresponding to a user wearing an HMD in a virtual space, a virtual camera control process of controlling a virtual camera moving in accordance with a movement of the moving body, and a display process of generating an image as viewed from the virtual camera in the virtual space as a display image of the head mounted display. The processor performs, in the display process, an image effect process for motion sickness prevention as a process of blurring, compared with a display object in a given distance range from the virtual camera, an image of a display object in a distance range farther than the given distance range to generate the display image.

An embodiment of the present invention provides a moving bike device including: a memory configured to store distance information and altitude information; a content implementation unit configured to adjust a reproduction state of content in response to a speed of a wheel depending on pedaling of a user; a controller configured to calculate a road slope from the distance information and the altitude information, and to calculate a travel distance depending on the pedaling of the user; and a road slope implementation unit configured to adjust strength of a brake in proportion to the road slope corresponding to the travel distance.

An indoor cycle linked to game content is proposed. More particularly, the indoor cycle includes an exercise equipment unit including a drum, pedals connected to the drum and provided with a built-in wireless pedaling sensor, a saddle provided above the drum, and handles connected to one side of the drum, a processor built into the exercise equipment unit to obtain sensor values from the wireless pedaling sensor, and configured to select a character from the game content to perform an operation of the selected character on the basis of the sensor values obtained from the wireless pedaling sensor, a controller provided in the handles and linked with the processor, so as to operate the character, and a display provided between the handles and linked with the processor, so as to display images of the game content.

A system and method for targeted neurological treatment using brainwave entrainment therapy with passive treatment that allows for targeted treatment of particular areas of the brain, particular neurological functions, particular neurological states, and combinations of areas, functions, and states. The system and method receive gait parameters for an individual and compare those against a database of historical gait data to determine if an onset neurodegenerative condition is present, and applies a brainwave entrainment therapy responsive to the determination of the condition. The system and method receive a neurological assessment identifying areas of the brain or neurological functions to be treated, select one or more treatment modalities and frequencies, select a treatment regimen, and apply brainwave entrainment using a treatment regimen while the subject engages in dual-task activities selected to stimulate the areas of the brain, neurological functions, or neurological states to be treated, enhanced, or altered.

An indoor, stationary, bicycle training device that provides advantages over conventional designs of exercise bicycles is provided. The stationary bicycle may include a tilting/pivoting mechanism to orient the indoor bicycle to simulate descending or climbing. The indoor bicycle may include flexible and resilient frame elements to support the indoor training device to move side-to-side under some riding situations thereby simulating the side-to-side swaying motion of an outdoor bicycle under the same riding situations. The indoor bicycle may include several combinations of frame adjustments to provide configurable dimensions of the indoor bicycle to adjust the frame to properly fit the rider, which may be adjusted based on corresponding dimensions of a user's outdoor bicycle. Still other aspects of the stationary bicycle device may aid in creating an “outdoor” feeling while using the device.

There is disclosed a system for conducting multi-member group competitions involving physical exertion, the system includes a competition server that serves to designate a set of parameters for a competition involving at least two competing groups of individuals engaged in physical activity, the set of parameters defining a win condition requiring physical activity to be completed by at least two separate individuals within each group. The system further receives data representative of physical activity of multiple individuals in a first group, receives data representative of physical activity of multiple individuals in a second group, determines whether the win condition has been satisfied by the first group or the second group, and identifies a winner as the first group or the second group that completed the win condition.

A paddling simulator includes a bar, a cable attached to the bar, a motor operationally coupled to the cable such that the motor can apply a force to the cable, and a controller configured to control the motor to generate a first tension in the cable during a propulsion phase of a paddling stroke and a second tension in the cable during a recovery phase of the paddling stroke.
