Postural sway during stance has been found to be sensitive to moving visual scenes in young adults, children, and those with vestibular disease. The effect of visual environments on balance in elderly individuals is relatively unknown. The purpose of this study was to compare postural sway responses of healthy elderly to those of young subjects when both groups were exposed to a moving visual scene. Peak to peak, root mean squared, and mean velocity of the center of pressure were analyzed under conditions combining four moving scene amplitudes ( 2 . 5 ∘ , 5 ∘ , 7 . 5 ∘ , 10 ∘ ) and two frequencies of scene movement (0.1 Hz, 0.25 Hz). Each visual condition was tested with a fixed floor and sway referenced platform. Results showed that elderly subjects swayed more than younger subjects when experiencing a moving visual scene under all conditions. The elderly were affected more than the young by sway referencing the platform. The differences between the two age groups were greater at increased amplitudes of scene movement. These results suggest that elderly are more influenced by dynamic visual information for balance than the young, particularly when cues from the ankles are altered.

Coordination And Control

This study investigated the coordination and control strategies that the elderly adopt during a redundant finger force coordination task and how the amount of visual information regulates the coordination patterns. Three age groups (20–24, 65–69, and 75–79 yr) performed a bimanual asymmetric force task. Task asymmetry was manipulated via imposing different coefficients on the finger forces such that the weighted sum of the two index finger forces equaled the total force. The amount of visual information was manipulated by changing the visual information gain of the total force output. Two hypotheses were tested: the reduced adaptability hypothesis predicts that the elderly show less degree of force asymmetry between hands compared with young adults in the asymmetric coefficient conditions, whereas the compensatory hypothesis predicts that the elderly exhibit more asymmetric force coordination patterns with asymmetric coefficients. Under the compensatory hypothesis, two contrasting directions of force sharing strategies (i.e., more efficient coordination strategy and minimum variance strategy) are expected. A deteriorated task performance (high performance error and force variability) was found in the two elderly groups, but enhanced visual information improved the task performance in all age groups. With low visual information gain, the elderly showed reduced adaptability (i.e., less asymmetric forces between hands) to the unequal weighting coefficients, which supported the reduced adaptability hypothesis; however, the elderly revealed the same degree of adaptation as the young group under high visual gain. The findings are consistent with the notion that the age-related reorganization of force coordination and control patterns is mediated by visual information and, more generally, the interactive influence of multiple categories of constraints.

Partial Compensation

This review summarizes our present knowledge about elderly people's problems with walking. We highlight the plastic changes in the brain that allow a partial compensation of these age-related deficits and discuss the associated costs and limitations. Experimental evidence for the crucial role of executive functions and working memory is presented, leading us to the hypothesis that it is difficult for seniors to coordinate two streams of visual information, one related to navigation through visually defined space, and the other to a visually demanding second task. This hypothesis predicts that interventions aimed at the efficiency of visuovisual coordination in the elderly will ameliorate their deficits in dual-task walking.

Practical Implications

Effective design and regulation of retirement benefits require accurate understanding of how the elderly decumulate. We analyse the income, assets and decumulation patterns of a longitudinal panel of 10,000 Australian age pensioners. On average, age pensioners preserve financial and residential wealth and leave substantial bequests. There is, however, considerable heterogeneity in decumulation patterns. Younger households generally run down financial wealth, while older households maintain their assets or save. Means-testing accelerates decumulation, with average drawdown rates 3% higher for pensioners subject to the income test relative to full pensioners and 9% higher for those subject to the asset test relative to full pensioners. Loss of a partner is linked to large falls in assets. The theoretical, empirical, and practical implications of these findings are discussed.

Walking Aid

The numbers of elderly people are rising in countries like India and China. Most of the elderly uses a walking stick for their commuting. Also blind peoples need a walking aid for their day to day life. This work mainly focuses on the design and development of a proactive walking aid for the blind and the elderly peoples. The stick is designed mainly using a ultrasonic sensors which is fit along with the existing hardware. This work analyses various difficulties that a person with disabilities faced in their life. So this work caters or handles most of the aspect an elderly or blind is needed using Internet of Things (IoT). Apart from the ultrasonic sensors it employs a buzzer that beeps when a person or object is approaching in front of the stick. Whenever a person with the stick get hit or stuck somewhere for a predefined time, then an alert along with the GPS coordinates sent to the emergency contact. Most of the literature supports a stick with reactive in nature, this work supports a proactive approach as it predicts the object at a distance rather than after it touches the stick. This system also employs machine learning algorithms to predict the nature of the person using the stick. Our results have shown that the stick can be the only aid that either an elderly or blind people can use.

Sensory Impairments

Since emotion recognition involves integration of the visual and auditory signals, it is likely that sensory impairments worsen emotion recognition. In emotion recognition, young adults can compensate for unimodal sensory degradations if the other modality is intact. However, most sensory impairments occur in the elderly population and it is unknown whether older adults are similarly capable of compensating for signal degradations. As a step towards studying potential effects of real sensory impairments, this study examined how degraded signals affect emotion recognition in older adults with normal hearing and vision. The degradations were designed to approximate some aspects of sensory impairments. Besides emotion recognition accuracy, we recorded eye movements to capture perceptual strategies for emotion recognition. Overall, older adults were as good as younger adults at integrating auditory and visual information and at compensating for degraded signals. However, accuracy was lower overall for older adults, indicating that aging leads to a general decrease in emotion recognition. In addition to decreased accuracy, older adults showed smaller adaptations of perceptual strategies in response to video degradations. Concluding, this study showed that emotion recognition declines with age, but that integration and compensation abilities are retained. In addition, we speculate that the reduced ability of older adults to adapt their perceptual strategies may be related to the increased time it takes them to direct their attention to scene aspects that are relatively far away from fixation.

<p><strong>The aging process brings various consequences in the form of physical, mental, and social problems so that an elderly person experiences limitations. The limitations of the elderly in carrying out their activities, especially in foot movement when walking, therefore a walking aid is needed. Each walking aid has a different function and usage method, one of which is a cane. Canes are often used to help balance, widen the stride and lower the weight on the legs. Safe and comfortable use is essential for the cane to function properly in assisting walking function. Canes still do not have a new design that suits the needs of the elderly. In this study, the development of a cane product for the elderly was carried out which was adapted to the ergonomic aspects and ideal aesthetic aspects. The aim is to provide convenience for the elderly in carrying out activities despite their limitations. Based on the research of the report on product development, namely Tongkat Wusaji using the Garvin Dimension method which is supported by 5 parts, namely performance, durability, features, serviceability, and aesthetics. It was found that the product concept applied to the Wusaji Stick uses aluminum material which has a product resistance of more than 3 years. The Wusaji stick has a minimalist design that is supported by the Bfinders and auto adjustable features and there are ergonomic usage procedures. Tongkat Wusaji has a product selling price of Rp. 250,000.</strong></p><p><strong><em>Keywords:</em> </strong><em>Identify customer needs, Product development, Product specifications, Industrial design</em></p>

In the course of normal aging, memory functions show signs of impairment. Studies of memory in the elderly have previously focused on a single sensory modality, although multisensory encoding has been shown to improve memory performance in children and young adults. In this study, we investigated how audiovisual encoding affects auditory recognition memory in older (mean age 71 years) and younger (mean age 23 years) adults. Participants memorized auditory stimuli (sounds, spoken words) presented either alone or with semantically congruent visual stimuli (pictures, text) during encoding. Subsequent recognition memory performance of auditory stimuli was better for stimuli initially presented together with visual stimuli than for auditory stimuli presented alone during encoding. This facilitation was observed both in older and younger participants, while the overall memory performance was poorer in older participants. However, the pattern of facilitation was influenced by age. When encoding spoken words, the gain was greater for older adults. When encoding sounds, the gain was greater for younger adults. These findings show that semantically congruent audiovisual encoding improves memory performance in late adulthood, particularly for auditory verbal material.
