Head diffraction effects on ear-level hearing aids.
In this paper, head baffle and head shadow effects were measured at a front-oriented and at a back-oriented microphone in a hearing aid casing when worn by human subjects and when placed on a dummy head. Some differences in head baffle and head shadow effects were observed for the front-and back-oriented microphones in that greater head baffle effects were observed at the front microphone than ...
متن کاملSmartwatches + Head-Worn Displays: the ‘New’ Smartphone
We are exploring whether two currently mass marketed wearable devices, the smartwatch (SW) and head-worn displays (HWDs) can replace and go beyond the capabilities of the mobile smartphone. While smartphones have become indispensable in our everyday activities, they do not possess the same level of integration that wearable devices afford. To explore the question of whether and how smartphones ...
متن کاملFall Detection Using a Head-Worn Barometer
Falls are a significant health and social problem for older adults and their relatives. In this paper we study the use of a barometer placed at the user’s head (e.g., embedded in a pair of glasses) as a means to improve current wearable sensor-based fall detection methods. This approach proves useful to reliably detect falls even if the acceleration produced during the impact is relatively smal...
متن کاملA mobile head-worn projection display.
A recent advancement was achieved in the integration and miniaturization of a binocular head-worn projection display (HWPD) conceived for fully mobile users. The devised display, referred to as Mobile HWPD (M-HWPD), offers see-through capability through custom-designed, light-weight projection optics and an integrated commercial-off-the-shelf (COTS) retro-reflective screen to display full color...
متن کاملBinocular Rivalry and Head-Worn Displays
OBJECTIVE We provide a review and analysis of much of the published literature on binocular rivalry that is relevant to the design and use of head-worn displays (HWDs). BACKGROUND This review draws heavily from both the basic vision literature and applied HWD literature in order to help provide insight for minimizing the effects of binocular rivalry when HWDs are worn. METHOD Included in th...
