![]() ![]() ![]() ![]() Here, we developed a novel framework that unifies the well-established inverted pendulum model with Goal-Equivalent Manifold (GEM)-based analyses to assess how humans regulate step-to-step balance dynamics to maintain mediolateral stability. To address mediolateral stability using MoS ML, we must first resolve this paradox. However, typical MoS ML -based analyses deliver paradoxical interpretations of stability status. Derived from inverted pendulum dynamics, the mediolateral Margin of Stability ( MoS ML ) is frequently used to measure people's frontal-plane stability on average. Maintaining frontal-plane stability is a major objective of human walking. Thus, the predictive capabilities of our general stepping regulation framework extend to a much greater range of walking tasks beyond just normal, straight-ahead walking. To our knowledge, our results are the first to demonstrate humans can use evolving cost landscapes in real time to perform such an adaptive motor task and, furthermore, that such adaptation can occur quickly – over only one step. Furthermore, their stepping behavior was well modeled by merely adapting the parameters of our previous lateral stepping models from step to step. Humans performed the experimental lateral maneuvers in a manner consistent with our theoretical predictions. Doing so yielded new theoretical predictions regarding how steps during any such maneuver should be regulated to minimize error costs, consistent with the goals required at each step and with how these costs are adapted at each step during the maneuver. Within our general lateral stepping regulation framework, we first re-examined the requirements of such transient walking tasks. Twenty young healthy adults each performed four lateral lane-change maneuvers in a virtual reality environment. Here, we used this framework to determine if humans can regulate lateral stepping during non-steady-state lateral maneuvers by minimizing errors in accordance with these goal functions. This framework yields goal functions for step width and lateral body position that define the walking task and determine the set of all possible task solutions as Goal Equivalent Manifolds (GEMs). We previously developed a theoretical framework and corresponding computational models to describe how humans regulate lateral stepping during straight-ahead continuous walking. As humans are more unstable laterally, we must better understand how humans modulate lateral foot placement. Humans accomplish these tasks primarily by modulating their foot placements. All in all, it's a definite 4.To successfully traverse their environment, humans must often perform maneuvers to achieve desired task goals while simultaneously maintaining balance. The fast games are pretty tense though and you'll find yourself playing 'just one more game' quite often. The gameplay can get a little tedious, because it takes quite some time to earn fifteen points, even against the weaker opponents. The sound is limited to speaker bleeps, which is adequate for this type of game. Nevertheless, your opponents are a colorful bunch. The 16 color EGA is better then the monochrome ones from the old Apple II I rembemer, but not as pretty as those on the Amiga. Each one has a certain amount of talent and some even have special tricks with which they might surprise you. Watch out though, 'cause some aliens tend to cheat a bit. First one to score 15 points by making his of her opponent miss the puck, wins the game. From the startup screen you simply click on your desired opponent to start a match against them. In Shufflepuck Café you have to become the champion by beating the current one, a greasy pig called Biff Raunch. The puck is more or less floating on the table due to a thin layer of air that's being blown over the surface (hence the 'air' in air-hockey). Both players have a paddle and use this to direct a puck all over the place. This is sort of like those air-hockey tables you might know from arcade halls. All they do is hang around and compete against each other in the game called Shufflepuck. What's the deal in "Shufflepuck Café?" Well, there's this café filled with a bunch of weird aliens (it might even be located in Mos Eisley on Tatooine, but this information is not available). Thank heavens it was released on other platforms as well (such as Atari, Amiga and of course, DOS) because Apple II's are hard to come by these days. If you have to summarize this game in one sentence it would be "Air hockey against aliens!". He had a little game on the thing however, which I was particularly fond of. Back then, I was not very impressed by the monochrome (and puny) display the thing had and I seriously mistrusted the mouse, because I was used to nice 16 colors, joysticks and big TV's from my own C64. When I was 12 years old, my father's neighbor had bought an Apple II.
