A new study by Carnegie Mellon University researchers found that real-time feedback on collaboration metrics does not improve team performance and can even make it worse. By narrowing the feedback to a single metric, teams focused too much on that signal and neglected coordination strategy, leading to decreased overall performance.
Researchers developed novel haptic devices to enable precise robot control with tactile feedback, reducing collisions and improving user proficiency. The devices integrate digital twin technology and augmented reality for enhanced immersion.
Researchers at Saarland University and ZeMA are developing smart film actuator technology using thin silicone films that can be precisely controlled to vibrate, flex, or press. These films enable wearable textiles to provide haptic feedback for enhanced VR gaming experiences and industrial gloves to respond to hand gestures.
A team of experts identified key challenges in wearable multisensory haptic devices, including variability in skin contact mechanics and tactile masking. However, emerging actuation methods like polymeric, fluidic, and thermal actuation offer promising solutions to expand the scope of haptic feedback.
A new study by Carnegie Mellon University researchers found that real-time AI feedback increases perceived trustworthiness and enhances workers' sense of their own work quality. This leads to increased trust in AI-generated performance ratings, particularly in non-routine work settings.
Researchers at Incheon National University have developed a new AI-powered solution to improve high-speed users' connectivity in 5G and 6G networks. The method significantly reduces errors and improves data reliability by prioritizing key parameters such as angles and delays.
A USC study reveals that forming social ties relies on learning from positive outcomes, such as rewards, and tracking relational value. The findings help explain why we are drawn to certain people and how we navigate relationships, with implications for mental health and social behavior.
A study found that pharmacists who received feedback about their heart failure patients increased the frequency of their patient interactions and prescribed more medication adjustments. The intervention, which provided educational resources and monthly audit and feedback emails, led to a significant increase in heart failure management.
A Northwestern University-led team developed a new haptic patch that delivers various complex sensations, including vibrations and twisting. The device has potential applications in gaming, virtual reality, healthcare, and sensory substitution, offering more realistic sensory experiences.
A novel study found that delayed feedback improves learning outcomes for individuals with moderate-to-severe traumatic brain injury. Delayed feedback may engage brain regions associated with memory retrieval and confidence, bypassing impaired pathways. The study suggests a valuable tool for improving learning in TBI individuals.
A recent study demonstrates how real-time haptic feedback can enhance interoceptive awareness, improving mental and physical health. Participants showed improved accuracy in heart rate discrimination tasks after receiving haptic feedback, suggesting a deeper connection between the mind and body.
A new surgical procedure reconnects muscles in the residual limb, allowing patients to receive proprioceptive feedback about their prosthetic limb's position. Seven patients who underwent this surgery were able to walk faster, avoid obstacles, and climb stairs more naturally than those with traditional amputations.
Researchers from GIST and MIT CSAIL develop a MultiSenseBadmpton dataset to enhance badminton performance analysis and AI-based coaching. The dataset captures joint movements, muscle signals, and gaze movements of badminton players.
Scientists have developed fUSI technology that enables clinicians to see and map the spinal cord's response to treatments in real-time. This innovation offers improved monitoring of blood flow changes, potentially increasing treatment success rates and optimizing pain relief for patients.
Researchers have created a computer using an array of VCSELs that leverages optical feedback to efficiently solve complex optimization problems. The system encodes information in linear polarization states, minimizing interactions between variables and overcoming the von Neumann bottleneck.
Researchers have developed a spinal cord stimulation technology that restores sensation, improves function, and reduces phantom limb pain after trans-tibial amputation. The study showed significant improvements in balance control and gait stability, with an average 70% reduction in phantom limb pain.
Researchers developed a neural network model to accelerate detection of brain rhythms, reducing feedback signal delay from 500ms to 10ms. The approach shows promise for treating attention deficit disorder and epilepsy.
Fruit fly research suggests visual system is involved in regulating social behaviors, which could have implications for understanding human psychiatric conditions such as autism and schizophrenia. Altering GABA signaling in the brain affects social inhibitions, leading to increased courtship behavior in males.
Researchers at Rice University developed wearable textile-based devices that utilize fluidic control to provide sophisticated haptic cues. The system enables users to navigate through real-world environments using tactile feedback, potentially enhancing visual and auditory inputs for those with impairments.
Researchers at City University of Hong Kong developed a wireless, soft e-skin for interactive touch communication in the virtual world. The e-skin can detect and deliver the sense of touch, enabling one-to-multiuser interaction and overcoming the limitations of space and distance.
Researchers found that shorter delays in neurofeedback training significantly increase efficacy, enabling sustainable changes. This breakthrough opens new potential for NFB therapy in anxiety, depression, epilepsy, and other conditions.
Researchers at Cold Spring Harbor Laboratory found that the mammalian brain uses cortical feedback to distinguish between nearly identical odors. The team tracked neural signals and found specific responses to distinct scents, suggesting a 'sparse' response and amplification of certain odors.
Researchers describe how feedback mechanism works by identifying where signals go and which neurons receive them. The study reveals that higher brain regions communicate with lower parts of the brain on a near-constant basis, helping to interpret olfactory information.
Researchers are developing a magnetic hearing aid that uses an electromagnetic coil to stimulate the inner ear via the round window, potentially enhancing speech and reducing background noise. The device could reduce or eliminate acoustic feedback, a common issue with conventional hearing aids.
