AR Crime Solving Using Chat-GPT

The Heist of the Century uses Chat-GPT to immerse you in realistic interrogations powered by conversational AI. Based on true facts, this latest episode tasks you with investigating an armored truck heist that took place in Montreal’s business center way back in 1976. As the lead detective, it’s up to you to interrogate five unique suspects and convince one of them to become your mole.

Each suspect is powered by AI based on Chat-GPT. You can ask virtually any question and receive a realistic and natural response from each suspect. Azure speech-to-text allows you to communicate with AI characters using your own voice, further immersing you in your role as a veteran cop. The CrimeTrip app was built using the Unity AR Foundation game engine.

HCI Synchronizes Brain Waves

An early, consistent finding is that when people converse or share an experience, their brain waves synchronize. Neurons in corresponding locations of the different brains fire at the same time, creating matching patterns, like dancers moving together. Auditory and visual areas respond to shape, sound and movement in similar ways, whereas higher-order brain areas seem to behave similarly during more challenging tasks such as making meaning out of something seen or heard. The experience of being on the same wavelength as another person is real, and it is visible in the activity of the brain.

Such work is beginning to reveal new levels of richness and complexity in sociability. In classrooms where students are engaged with the teacher, for example, their patterns of brain processing begin to align with that teacher's, and greater alignment may mean better learning. Neural waves in certain brain regions of people listening to a musical performance match those of the performer, the greater the synchrony, the greater the enjoyment. Couples exhibit higher degrees of brain synchrony than non-romantic pairs, as do close friends compared with more distant acquaintances.

Robots Learn From Videos

New work from Carnegie Mellon University has enabled robots to learn household chores by watching videos of people performing everyday tasks in their homes. The research could help improve the utility of robots in the home, allowing them to assist people with tasks like cooking and cleaning. Two robots successfully learned 12 tasks including opening a drawer, oven door and lid; taking a pot off the stove; and picking up a telephone, vegetable or can of soup.

Current methods of training robots require either the manual demonstration of tasks by humans or extensive training in a simulated environment. Both are time consuming and prone to failure. The new model eliminates the necessity of human demonstrations as well as the need for the robot to operate within an identical environment. Like WHIRL, the robot still requires practice to master a task. The team’s research showed it can learn a new task in as little as 25 minutes.
