ANN ARBOR, Mich. (AP) — A University of Michigan research team has created an augmented reality system that allows people with different levels of mobility to play and exercise together. The research prototype of iGYM projects a court onto the floor and can host several games, including one that is a hybrid of soccer and air hockey. Players are surrounded by a circle that can be expanded to strike virtual targets, such as a ball player can guide into their opponent’s goal. Professor Roland Graf and his team are looking for partners to bring iGym to the market.

CONSTANTINE, Mich. (AP) — A man who served 20 months in custody for a wrongful conviction is suing police in southwestern Michigan.

McCann’s lawsuit says his rights were violated during a “corrupt scheme” by police. Another man confessed to killing Jodi Parrack.
