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. 

UNDATED (AP) — Recreational marijuana sales totaled about $1.6 million in the inaugural week of business at the first retail shops in Michigan. The Detroit Free Press and MLive.com report sales during the Dec. 1-8 period brought the state roughly $270,400 in revenue from the excise and sales taxes levied on pot. Michigan’s Marijuana Regulatory Agency has issued 10 retail licenses for recreational marijuana, five of which began selling last week. More than 1,400 of Michigan’s nearly 1,800 cities, townships and villages aren’t allowing pot shops. Illinois starts recreational sales in January.

CONSTANTINE, Mich. (AP) — A man who served 20 months in custody for a wrongful conviction is suing police in southwestern Michigan. Ray McCann was repeatedly hounded by police during an investigation of a girl’s killing in St. Joseph County. McCann denied any role in the death of the 11-year-old girl but says he felt pressured to plead no contest to perjury. The conviction was thrown out in 2017 at the request of a prosecutor. McCann’s lawsuit says his rights were violated during a “corrupt scheme” by police. Another man confessed to killing Jodi Parrack.
