Abstract In this paper, a metasurface-based waveguide display equipped with an eye movement monitoring system is presented. In the suggested device, the functions of the eye movement system and AR are completely independent of each other and are designed in two separate sections at wavelengths 775 nm and 635 nm respectively. In the next part, in order to investigate the effects of the shape of the waveguide on FOV and efficiency, a multifunctional display system comprise of a single rectangular waveguide with two sensitive polarization channels are designed to operate as an AR and eye movement monitoring system simultaneously at visible and IR wavelengths respectively. In both devices, monitoring eye movements can be done over the range of -24º to 24º and the digital images are displaced in the user’s FOV based on horizontal eye positions. Although the first suggested system is heavier than one, its FOV is almost more than twice of the second system. The results indicate that metasurface-based waveguide technology can be considered as an appropriate platform for developing wearable eye movement systems.

BACKGROUND: The manner in which shooters pull the trigger may significantly affect the shooter’s results. Shooting coaches are often not able to detect incorrect pull because of gun movement during the shot and recoil. OBJECTIVE: Development of the smart-textile based trigger pull monitoring system and demonstration of its ability to distinguish correct and wrong triggering techniques. METHODS: Two separated knitted resistive pressure sensors were integrated over III and II phalanges in the index finger fingerstall; single sensor was integrated over both III and II phalanges of the middle finger fingerstall. Resistance of the sensors was measured in a course of shots, performed by expert shooter, which simulated typical novice’s trigger pull errors. RESULTS: Sensors’ resistance recordings were made for following erroneous trigger pull motions: pulling of the trigger with index finger’s II phalanx instead of III; fast and jerky trigger pull (trigger tear-off); too fast release of the trigger after shot; and excessive grip force, applied by middle finger. For each type of erroneous movement, recordings waveforms included distinguishable features that characterised a particular type of error. CONCLUSIONS: The developed trigger pull monitoring system provides signals that could be used for recognition of the incorrect trigger pull motions during gun shots.

Person-to-person communication is ubiquitous in everyday life, yet the literature on framing has not examined how the content and number of frames change when transmitted across individuals. In Study 1, we use the serial reproduction paradigm to examine how person-to-person communication and message length influence the number of frames in the information environment. In Study 2, we use eye movement monitoring to examine whether individuals direct greater attention to pro- or counter-attitudinal frames in a competitive framing environment. We find that the process of retelling frames from person to person can transform an environment containing multiple competing frames into an environment with a single frame. This is important given work showing that framing effects in competitive environments are more likely to cancel out. Furthermore, message length and prior attitudes play important roles in determining whether individuals direct attention to, remember, and transmit frames.
