System and method for assessing eyesight acuity and hearing ability

Abstract

The present invention relates to a system (10) for assessing eyesight acuity of a subject (20), comprising: a display (12) for displaying graphics and / or text to the subject (20); an eye movement sensor (14, 14') for monitoring an eye movement of the subject (20) while the subject (20) is watching the graphics and / or text displayed on the display (12); a processing unit (16) for assessing the eyesight acuity of the subject (20) based on an analysis of the monitored eye movement, wherein the analysis of the monitored eye movement includes an analysis of at least one of a duration of eye saccades, a frequency of eye saccades, a duration of eye fixations and a frequency of eye fixations in the monitored eye movement; and an output unit (18, 18') for indicating the result of the assessment of the eyesight acuity. The present invention furthermore relates to a system (110) for assessing hearing ability of a subject (20).

Description

technical field [0001] The present invention relates to a system for assessing the visual acuity of a subject. The invention also relates to a system for assessing the hearing ability of a subject. Furthermore, the invention relates to corresponding methods for assessing the visual acuity and hearing abilities of a subject. Furthermore, the invention relates to a computer program for carrying out said method. Background technique [0002] The care of the elderly has become increasingly important because population aging is a well-known trend in many countries. Care of the elderly becomes an increasingly challenging task, especially due to the limited number of doctors and trained nursing staff. In many cases a large number of older persons must fend for themselves. Therefore, suitable equipment for self-care is extremely important. [0003] In general, independence and self-care activities of older adults are critical to maintaining their state of health, physical fitne...

AI Technical Summary

Problems solved by technology

These rare and discrete measures of patient ability do not accurately capture trends in visual and auditory abilities, often resulting in delayed support because the moment when the patient begins to deteriorate and thus requires support is not captured

This has the following disadvantages: 1. For elderly patients with vision and hearing problems, it is troublesome to make an appointment with the doctor, because they are already dependent on others (eg for transportation)

2. Trends in vision and hearing deterioration are unlikely to be detected early enough to enable adequate and effective intervention

3. Nurses are only informed of patient status at the time of appointment, which may be too late, leading to more significant and / or advanced intervention, which often implies increased patient discomfort, higher cost and less likelihood of success

4. Such an approach implies an increased risk of adverse events (such as exacerbation of COPD or heart failure) in all patients due to non-adherence to medication as patients become less able to read their prescriptions
