Simulating the effect of ankle plantarflexion and inversion-eversion exoskeleton torques on center of mass kinematics during walking

Prof. Scott Delp, Prof. C. Karen Liu, Prof. Steven Collins et al used musculoskeletal simulation to evaluate the effect of exoskeleton torques on walking kinematics and highlight how muscle properties influence the dynamics of human-device interactions, giving designers a guide for building exoskeletons aimed at improving gait stability.

Off-axis metasurfaces for folded flat optics

Prof. Mark Brongersma et al describe an off-axis metasurface architecture that uses low-aspect-ratio, low-refractive- index, dielectric elements to enable low-cost large-area manufacturing and reduced optical path volume for folded optical systems, such as AR/VR imaging devices.

Towards attention-aware foveated rendering

Prof. Gordon Wetzstein et al introduce the first attention-aware model of contrast sensitivity with foveated graphics, which is a promising approach to solving the bandwidth challenges of immersive virtual and augmented reality displays by exploiting the falloff in spatial acuity in the periphery of the visual field.
