This precludes the Deaf\/Hard-of-Hearing (HoH) community from benefitting from advances in technology, which, if designed to be compatible with ASL, could in fact generate tangible improvements to their quality of life. <br><br>My research aims at transforming ubiquitous sensing technologies through the integration of a new sensing modality &#8211; radio frequency (RF) sensing or radar &#8211; into smart environments designed to respond to the needs of ASL users. <br><br>RF sensors are uniquely desirable for this application because they are 1) non-contact, 2) can operate in the dark or through-the-wall, 3) protect privacy as they cannot acquire visual images of the user or environment, and 4) bring to bear a new type of information that aides in ASL recognition: namely, the micro-Doppler signature, which is reflective of the time-varying velocity profiles of motion. Thus, RF sensing can capture the kinematics of the rapid progression of dynamic sign sequences that is characteristic of ASL usage. <\/p>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Meet the Team:<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"541\" src=\"https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/RFASL_TEAM-1-1024x541.png\" alt=\"\" class=\"wp-image-1267\" srcset=\"https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/RFASL_TEAM-1-1024x541.png 1024w, https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/RFASL_TEAM-1-300x159.png 300w, https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/RFASL_TEAM-1-768x406.png 768w, https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/RFASL_TEAM-1.png 1203w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Thanks to our Sponsors:<\/h3>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:20%\">\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1019\" height=\"1024\" src=\"https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/NSF_4-Color_bitmap_Logo_RGB-3.png\" alt=\"\" class=\"wp-image-1269\" style=\"aspect-ratio:0.9951264087724642;width:161px;height:auto\" srcset=\"https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/NSF_4-Color_bitmap_Logo_RGB-3.png 1019w, https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/NSF_4-Color_bitmap_Logo_RGB-3-300x300.png 300w, https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/NSF_4-Color_bitmap_Logo_RGB-3-150x150.png 150w, https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/NSF_4-Color_bitmap_Logo_RGB-3-768x772.png 768w\" sizes=\"auto, (max-width: 1019px) 100vw, 1019px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"356\" height=\"141\" src=\"https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/gu-4.png\" alt=\"\" class=\"wp-image-1271\" style=\"width:286px;height:auto\" srcset=\"https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/gu-4.png 356w, https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/gu-4-300x119.png 300w\" sizes=\"auto, (max-width: 356px) 100vw, 356px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"342\" height=\"147\" src=\"https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/aauw-3.png\" alt=\"\" class=\"wp-image-1272\" style=\"width:291px;height:auto\" srcset=\"https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/aauw-3.png 342w, https:\/\/research.ece.ncsu.edu\/ci4r\/wp-content\/uploads\/sites\/40\/2025\/12\/aauw-3-300x129.png 300w\" sizes=\"auto, (max-width: 342px) 100vw, 342px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p class=\"has-slightly-smaller-font-size\"><strong>National Science Foundation (NSF) Award #193257<\/strong>: &#8220;<a href=\"https:\/\/www.nsf.gov\/awardsearch\/show-award?AWD_ID=1932547\">CPS: Small: Collaborative Research: RF Sensing for Sign Language Driven Smart Environments<\/a>&#8221; [10\/1\/2019-10\/31\/2022, $366,252] [10\/1\/2022-3\/31\/2023, $50,000] <br>Lead PI: Dr. Sevgi Z.
