As the necessity of haptic technology in the metaverse area has been increasing, a number of glove-shaped haptic devices have been developed and commercialized. However, current commercialized devices are highly expensive for not only developing countries but also for average individuals. Therefore, this paper sets out to present an affordable and practically usable haptic glove. The three main elements contested in this paper are Leap Motion Controller (LMC), which is used to improve and stabilize the recognition of hand tracking in Unity. Elasticity, which pertains using string-based haptic feedback wherein our Haptic Glove generates an elastic effect of a virtual object. Lastly, an EMG sensor: By connecting the EMG sensor and the Haptic Glove, this paper proposes the possibility of expanding the use of the Haptic Gloves for fine motor development and rehabilitation.

The present study is the first one to investigate the impacts of depression and somatization on the disease severity and quality of life (QoL) in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). The Korean version of National Institutes of Health (NIH)- Chronic Prostatitis Symptom Index (CPSI) for severity of CP/CPPS. Korean version of Patient Health Questionnaire-9 (PHQ-9) for depression, Korean version of Patient Health Questionnaire-15 (PHQ-15) for somatization, and Korean version of EuroQol Questionnaire-5 Dimensions (EQ-5D)- [(EQ-5D utility index and visual analog scale (EQ-5D VAS)] for QoL, were administered. Eighty patients were enrolled. The NIH-CPSI total scores were significantly higher in those with depression (25.3%, p=0.01) or somatization (23.2%, p=0.03) than in those without. These trends toward significantly negative influence of depression and somatic symptoms on QoL were also observed. Our preliminary results indicate that depression and somatization may have negative influence on the symptom severity and QoL in patients with CP/CPPS. However, adequately-powered and more well-designed studies are mandatory to prove our results.

This study investigated the relationship of personality, depression, somatization, anxiety with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). The LUTS/BPH patients were evaluated with the International Prostate Symptom Score (IPSS), 44-item Big Five Inventory (BFI), the Patient Health Questionnaire-9 (PHQ-9), the PHQ-15, and 7-item Generalized Anxiety Disorder Scale (GAD-7). The LUTS/BPH symptoms were more severe in patients with depression (p=0.046) and somatization (p=0.024), respectively. Neurotic patients were associated with greater levels of depression, anxiety and somatisation (p=0.0059, p=0.004 and p=0.0095, respectively). Patients with high extraversion showed significantly low depression (p=0.00481) and anxiety (p=0.035) than those with low extraversion. Our exploratory results suggest patients with LUTS/BPH may need careful evaluation of psychiatric problem including depression, anxiety and somatization. Additional studies with adequate power and improved designs are necessary to support the present exploratory findings.
