Interim Police Superintendent John Escalante said the city looked at 15 police departments, including New York, Seattle, Portland, Cincinnati and Cleveland as it developed its new policies.
Meanwhile, more protests were planned in Cleveland on Wednesday, two days after a grand jury decided not to charge two white police officers in the 2014 shooting death of Tamir Rice, a black 12-year-old boy who was playing in a park with a toy gun that shoots plastic pellets.
Cleveland officials said on Tuesday they will review Rice's shooting to determine if the officers involved or others should face disciplinary action.
Tensions over race and policing in Chicago and Cleveland come amid intense scrutiny of police killings in the United States over the past 18 months, especially of black men. Protests have taken place around the country.
Not all Chicago police officers are currently equipped with Tasers, which are electroshock weapons that fire dart-like electrodes that incapacitate but are non-lethal.
In Chicago, protesters have called for Emanuel's resignationafter a video was released last month showing Chicago Police Officer Jason Van Dyke, who is white, shooting Laquan McDonald, 17, in 2014. Van Dyke has pleaded not guilty to murder.
The ensuing turmoil led Emanuel to fire the police superintendent and create a task force to review police accountability.
While Emanuel was vacationing in Cuba, Bettie Jones, 55, and Quintonio LeGrier, 19, were killed on Dec. 26 by an officer responding to a call that LeGrier was threatening his father with a baseball bat.
Activists were skeptical Wednesday that the changes would reverse decades of problems and mistrust between Chicago residents and police.
Ted Pearson, one of the leaders of the Chicago Alliance Against Racist and Political Repression, noted that Emanuel made leadership changes after the release of the McDonald video and gave a speech before the City Council in which he apologized, appearing at times to be near tears. Yet that didn't stop the latest shooting.
Pearson's organization believes the only way to bring true change is for Chicago to have a civilian police accountability council that isn't appointed by the mayor.
"The people have no trust in the police. They have no trust in the mayor," Pearson said. "The people in charge are continuing to give (some officers) a pass. It happens over and over and over again."
