“…Therefore, the positive persistency characterized by the scaling exponent α could be a good index that reflects endogenous gait stability/instability and a risk of falls. Because exogenous factors, such as stepped surface and surrounding pedestrians, could cause a fall easily, increase in the fall incident during walking with usages of a smartphone 9 might be due to both endogenous and exogenous factors. However, note that the mechanisms of how the positive persistency is generated through a control process for stabilizing gait has yet to be clarified 60 – 62 , and thus also mechanisms of how the positive persistency is declined that lead to an increase in a risk of falls has not yet been established 61 .…”

“…Kim et al reported that people who are addicted to smartphones are more likely to have experienced falls compared with normal users 6 . Recent studies report that using a mobile phone to text while walking may compete with locomotor tasks, threat assessment and postural balance control mechanisms, which leads to an increased risk of accidental falls in young adults 7 – 9 . In this way, prevention of falls is a priority for our societies.…”

Gait cycle variability during steady walking, described by the stride interval time series, has been used as a gait-stability-related measure. In particular, the positive persistency in the stride intervals with 1/f-like fluctuation and reduction of the persistency are the well-documented metrics that can characterize gait patterns of healthy young adults and elderly including patients with neurological diseases, respectively. Here, we examined effects of a dual task on gait cycle variability in healthy young adults, based on the mean and standard deviation statistics as well as the positive persistency of the stride intervals during steady walking on a treadmill. Specifically, three gait conditions were examined: control condition, non-cognitive task with holding a smartphone in front of the chest using their dominant hand and looking fixedly at a blank screen of the smartphone, and cognitive motor task with holding a smartphone as in the non-cognitive task and playing a puzzle game displayed on the smartphone by one-thumb operation. We showed that only the positive persistency, not the mean and standard deviation statistics, was affected by the cognitive and motor load of smartphone usage in the cognitive condition. More specifically, the positive persistency exhibited in the control and the non-cognitive conditions was significantly reduced in the cognitive condition. Our results suggest that the decrease in the positive persistency during the cognitive task, which might represent the deterioration of healthy gait pattern, is caused endogenously by the cognitive and motor load, not necessarily by the reduction of visual field as often hypothesized.

“…The SCAMPER method is used in this study to formulate innovative ideas aligned with consumer market needs, particularly those targeting Generation Y and Z. The reason for choosing Generation Y and Z, or the "digital natives," is that they are individuals raised in a digital media-rich environment and show a significant dependence on smartphones in their daily routines [23], thus creating a consumer base ready to adopt VR technology.…”

Startups often face uncertainty and the potential Valley of Death. To address these challenges, Sustainable Development Goals (SDGs) can serve as a starting point to identify business opportunities in markets driven by SDG-related issues. In this case, we propose using virtual reality (VR) technology as a “painkiller”. This study aims to explore VR use cases and their implications for startup business models and discover a problem–solution fit, i.e., identify the degree to which VR applications effectively address actual problems as “killer applications”. The study employs a customized customer discovery technique, an essential process in the Customer Development methodology. By exploring VR’s applicability in various domains such as entertainment, training, education, and tourism, this study unveils compelling use cases that align with SDG aspects, thus validating the hypothesis on startups’ potential to harness VR for SDG contributions. Furthermore, the study produces VR business model designs based on solutions to SDG-related problems. Thus, startups can function effectively as “painkillers”, offering solutions that are not only desired but urgently needed (problem–solution fit). The implications of these findings extend globally, underlining VR’s role in addressing SDG issues and offering practical insights for startup business model development that are applicable to broader technology adoptions.
