Vistendo proposes to develop a portable, real-time, non-invasive, objective, and cause-agnostic impairment screening device (PHID/ Physiological Health and Impairement Detector) to identify impairments before an individual starts to feel sufficiently unwell for self-reporting, or the appearance of overt clinical symptoms and significant impairments. These conditions can be quantified using physiological and neurological indicators and relevant changes beyond normal daily variations in these indicators can serve as early warning signs of potential impairments. A positive result of having significant and relevant deviations in multiple indicators will essentially indicate suspicion of impairments that warrant confirmation in combination with other risk factors and further testings. PHIDâs manufacturable design combined with over-the-air upgradability enables scalable, rapid, low burden deployment even for non-ideal on-the-field environment. In this proposal, we will demonstrate the feasibility of the PHID in identify early signs of impairments
