Algorithm Enables Cameras To Recognize Distinctive Exercise Motions
Wearable sensors such as smartwatches have become a popular motivational tool for fitness enthusiasts, but gadgets do not sense all exercises equally. Researchers at Carnegie Mellon University have found that a stationary camera is a better choice for gym exercises.
Physicians making life-and-death decisions about organ transplants, cancer treatments or heart surgeries typically don't give much thought to how artificial intelligence might help them. And that's how researchers at Carnegie Mellon University say clinical AI tools should be designed — so doctors don't need to think about them.
Thousands of the world’s top researchers, scientists, and designers are traveling to the ACM CHI Conference on Human Factors in Computing Systems (also known as CHI) this weekend. The premier international conference of Human-Computer Interaction will take place in Glasgow, UK from May 4-9, 2019.
Several from Carnegie Mellon University’s Human-Computer Interaction Institute were honored by Fast Company in its annual Innovation by Design Awards. Two projects from the HCII were finalists and two more earned honorable mentions in 2018.
3D printing has been quietly moving towards a radical revolution over the past several years. While it has already exceeded 5.1 billion, its growth has been relatively slow, and not as disruptive as some might have envisioned. Instead, 3D printing has been advancing to its quiet revolution through applications like medical technology and industrial manufacturing.
Heart patients who have reached end-stage heart failure may have a pump surgically inserted to help blood flow to the rest of the body. This mechanical implant is called a ventricular assist device (VAD), and it can prolong and improve patients' lives. Though physicians have been performing this surgery for years, the patient outcomes are not as predictable as might be expected. While some patients do very well post-surgery, others do not live long after receiving a VAD. In additional cases, patients who seem to be viable candidates for the surgery never receive the device.
In early October 2016, rapper Kid Cudi made the headlines after writing on Facebook that he entered rehab for treatment for depression and suicidal thoughts. While he’s not as famous as other musicians, his heartfelt message garnered a lot attention and support from celebrities and mental health professionals.
“Yesterday I checked myself into rehab for depression and suicidal urges. I am not at peace. I haven't been since you've known me. If I didn't come here, I would’ve done something to myself,” he wrote.
Despite the existence of successful online groups, the majority of newly created ones fail. They don’t survive, fail to attract enough digital users, or don’t meet goals their founders set for them. Herbert A. Simon Professor of Human-Computer Interaction Robert Kraut has dedicated much of his recent research to investigating why some groups succeed where others fail.
We have built an emotion recognition system based on prosodic features (i.e. intensity, pitch, formant frequencies of sounds) combined with short-term perceptual features for classifying the following emotions: anger, fear, happy, sad, surprise, and neutral. Additional emotional states can be included. Prosodic information applies to syllables, words, or phrases. An interactive dialog elicits responses from the user.
