The discussion centers on the potential interest in a device that simulates walking, such as an omni-directional treadmill, for gamers. Participants express skepticism about the affordability and practicality of such a product, noting that it could be expensive once safety and technical issues are resolved. There is a suggestion that renting out this technology to VR arcades or gyms might be a viable business model, as it could enhance the experience of traditional exercise equipment. Some participants believe that incorporating walking simulations into gaming could make workouts more engaging, especially for those who find treadmills monotonous. The conversation also touches on existing products like the Wii, which have attempted to create interactive gaming experiences, but questions remain about the immersive quality of these alternatives compared to actual physical activity. Overall, the idea of a walking simulation device garners interest, but concerns about cost and practicality are significant.
