This study was performed to investigate the characteristic of physical touch in caring situation. The subjects of this study were adults in caring situation, therefore they were composed of 7 patients, 6 nurses, 3 doctors, 3 pharmacologists, 3 men in paramedicine area, 3 nursing educators and 13 normal general adults. The datas were gathered through nonstructured questionaire from June, 20th to September, 15th in 1995. The datas were subjects' descriptions about the intention, perception, and form of physical touch in caring situation and analysed by content analysis. The results as follow : The datas were divided into four areas. There were the situation being necessiated the physical touch, meaning of physical touch, form of physical touch and perception about physical touch in caring situation. The situation being necessiated physical touch were the situation that required physical treatment, to deliver the active expression of concern about the patients, to determine the treatment due to the identification of physical condition of patients and to induce the psychological eqilibrium into patient's mind. The meanings of physical touch in caring situation were - Good meanings that intention is to encourage, to be have hope about health and to deliver the affection willing to help patient. - therapeutic methods that were to facillitate the circulation of blood, to reduce the pain perception and to facillitate the circulation of qi. - interpersonal affectionate relation that the intentions were to deliver the understanding of patient's pain, were to delivery the meaning to the patient not be alone. The forms of physical touch in caring situation were none invasive forms just like laying hands on hand, head, shoulder, gentle knocking on the shoulder or back, massage of legs and back and finger pressure on acupuncture points. The perception of physical touch in caring situation divided into two parts. In family, the perceptions of physical touch in caring situation were to promote health status because physical touch induce the psychological peace, and to evoke the importance of relationship among family members. In relation with care giver, perception of physical touch in caring situation were inevitable process in treatment, and to deliver the trust and concern about patients.

This study evaluated the effects of physical touch play programs in children through a systematic literature review and meta-analysis. A literature search for journal articles published before August 2022 was conducted using KERIS, KISS, DBpia, and ScienceON. The keywords used for the search were 'child', 'infant', 'physical touch', 'physical touch play', 'physical touch activities' and 'physical touch play program'. For the study's purpose, seven studies were selected through a systematic process of using several databases and were used to estimate the effect size of physical touch play programs. A meta-analysis was performed using a random effects model, and the effect size on cognitive function was calculated. Hedges' g of the physical touch play program was 6.20 (95% CI: 3.74-8.66), indicating a large effect size. To determine heterogeneity (I2= 95.4%, Q = 417.30, p<0.001), moderator analysis was performed using the total number of times and intervention duration. The total number of times was statistically significant; the other moderators did not differ significantly. This study systematically analyzed the results of physical touch play programs on children in Korea. It also provides insights that can be applied to the design of physical touch play programs for children. To present more evidence that supports the effectiveness of physical touch programs, further research is warranted.

Purpose: This study examined the effect on postural control during the stimulation of haptic touch with fingertip on the stable surface at quiet standing posture, squat flexion stage, 60 degrees squat stage and squat extension stage. Methods: The postural sway was measured on the force platform, while 30 subjects were squatting, under three different haptic touch conditions (No Touch [NT], Light Touch [LT], Heavy Touch [HT]), above the touch pad in front of their body midline. Three different haptic touch conditions were divided into 1) NT condition; squatting as right index fingers held above the touch pad, 2) LT condition (<1N); squatting as the touch pad was in contact with right index fingers pulp with a pressure not exceeding 1N and 3) HT condition; squatting as subjects were allowed to use the touch pad for mechanical support by transmitting onto it with as much force, choosing with their index fingers. Results: There was significant decrease in LT, rather than that of NT (p<0.01), and in HT, rather than that of LT (p<0.01), as the results of the distance and velocity of center of pressure (COP) in mediolateral direction at quiet standing position. In anteroposterior direction, the distance and velocity of COP in LT and HT showed significant decrease, when compared to that of the data of NT (p<0.01). There was no significant difference between the 3 conditions (NT, LT, and HT), with respect to the distance and velocity of COP in mediolateral direction, during dynamic balance (squat flexion stage, squat extension stage) (p>0.05). In anteroposterior direction, the results of the distance and velocity of COP in HT showed significant decrease when compared to that of the data of NT (p<0.05). Conclusion: Light touch, during the task, decreased the postural sway at static balance. The results suggest that haptic touch should be applied, appropriately, because it varies the effects according to different conditions.

Recently, as the demand for multimedia services based on the wireless technologies and mobile devices increases, Full-touch screen mobile devices adopting touch screen keyboards are emerging to cope with the limited display size and take advantage of the flexibility in the design of user interfaces. However, the text entry task, which is one of the main features of the mobile devices, decreases the competitive advantages of the touch screen keyboards over the physical keyboards or keypads due to the lack of physical feedbacks and the frequent occurrence of mistyping. This study aims to introduce a novel text entry method named Fuzzy Touch and compare this method with the conventional text entry method on a touch screen keyboard in terms of the performance (time, number of touch) and the subjective ratings (ease of use, overall preference).

Background: The purpose of the present study was to determine whether balance training combined with light touch improves the postural sway and gait speed in stroke patients. Design: Randomized Controlled Trial Study Methods: The current study included 40 stroke patients, who were randomly divided into two groups: the balance training with light touch (LT) group (n=20) and the balance training with heavy touch (HT) group (n=20). Both groups performed balance training on a stable and unstable ground. Additionally, the LT group provided light touch stimulation, and the HT group provided heavy touch stimulation. All the participants underwent 20 sessions of STS training (thirty minutes, five days per week for four weeks). In this study, postural sway was measured using a force platform, and walking speed was measured using a 10 meter walk test. Results: The improvements in postural sway and gait speed were observed to be significantly greater in the LT group, compared to the HT group (p<0.05). Conclusion: The results of the current study imply that balance training combined with light touch is a beneficial and effective therapeutic modality that can be employed to improve the postural sway and gait speed in stroke patients.

Objective: The purpose of this study was to investigate how light touch with a finger affects balance ability when a posture is maintained in the condition of visual information blockage and to provide a fundamental material for developing balance ability in the process of rehabilitation treatment. Design: Cross-sectional study. Methods: The study subjects were 17 healthy men and women in their twenties and thirties who were studying at S University in Seoul. The system was comprised of an equilateral triangular force platform. Subjects were asked to step on the foot position of the force platform (Good Balance, Finland) barefooted for 30 seconds, with eyes closed, hands hanging down loosely, and feet comfortably apart. It was connected to a laptop by using Bluetooth technology. An experiment was conducted in the following three circumstances: 1) no-touch trial, 2) light touch to the back (T7 area), and 3) light touch to the middle finger of the left hand. Each subject was given a 10-minute break between consecutive measurements. The experimental circumstances were performed randomly. Anteroposterior sway (APSV), mediolateral sway velocity (MLSV), and velocity moment (VM) were measured. Results: The APSVs (mm/s) were $9.32{\pm}3.37$ and $5.45{\pm}2.98$; the MLSVs (mm/s), $6.39{\pm}3.35$ and $3.31{\pm}2.48$; and VM ($mm^2/s$), $17.13{\pm}11.75$ and $6.76{\pm}8.31$ in the first and second experimental circumstances, respectively. APSV, MLSV, and VM values were significantly improved with the 1) no-touch trial and 2) light touch to the back trail conditions compared with the 3) light touch to the middle finger of the left hand condition (p<0.05). Conclusions: This study revealed that the balance ability for maintaining a body posture was influenced more by light touch to the back (T7) than by light touch with the sensitive fingertip and body sway diminished after visual information was blocked.

The trends in nursing practice are not disease-oriented approaches but holistic, humanistic approaches such as human touch, which is an easily applied, economic, and efficient intervention. The purposes of this paper were to clarify the meaning of the concept "touch" to define the precise attributes of “touch” which could be a basis for nursing interventions. This study uses Walker & Avant's process of concept analysis. The concept of touch can be defined as follows : Touch is a process of communication and physical contact with intention, which is transfered by tactile senses. Attributes of touch are defined as 1) It is transferred by tactile senses. 2) A process of communication 3) A expressive pathway of emotion 4) It has intention. Antecedents of "touch" consist that 1) the touch provider understands the touch receiver's perception of past experiences of touch : 2) the touch provider is concerned about the touch receiver and comes up to the touch receiver : 3) the touch provider wants to deliver his /her emotions ; 4) the touch receiver needs the ability to differentiate the tactile senses. In regard to the consequences of touch, it is expected to keep the touching action between the touch provider and receiver, to feel empathy, to able to perceive the consumer's needs, to feel comfort, intimacy, trust, and to calm down the physiological variables. That is performing the nursing as a caring science.

This research investigated the effects of cool touch fabrics on thermo-regulating physical properties and subjective evaluation using a 3D fitted women's T-shirts in wear test. Qmax, clothing microclimate, microclimate wettedness, thermogram and subjective vote were observed during rest-right after an exercise-rest protocol. As a result, there was no single determining physical variable to explain the reasons of cool sensations of T-shirts made of cool touch fabric across the entire protocol. Qmax could partly predict a wear sensation at the initial stage when only insensible perspiration was presented. Simultaneous observation of temperature/humidity gradient understand from the inside to the outside of the clothing layer or microclimate wettedness calculated using vapor pressure were helpful to figure out the performance of cool touch fabric, especially at the later stage of the protocol when sweating was excessive. It was especially difficult to connect thermo-regulating physical variables to the subjective evaluation during transient conditions such as 'right after exercise' stage. It is necessary to measure the amount of heat and moisture transferred from the skin to the outside of clothing along with the physical properties measured in this study to understand the detailed mechanisms of why a cool sensation is evoked from tight fitting T-shirts made of newly developed cool touch fabrics.

This paper proposes the physical human-robot interaction method that controls the robot arms using ITO touch panel sensor as the skin of robot. To implement physical human-robot interaction, the method of using the force/torque sensor and the method of using tactile sensor created by arranging small element type of sensor have been studied. However, these sensors have the pros and cons in terms of price and performance. This study aims to demonstrate the economy of element type sensor and the accuracy of force/torque sensor through experiment by proposing the method of physical interaction using the touch panel as the skin of robot, and by constructing overall system. The experiment was carried out for the method of controlling the robot arm by installing end-effecter and the method of controlling robot arm by creating the gesture with reference point on the touch panel. Through this experiment, the possibility of teaching control using the touch panel was confirmed.

This study proposed 'Body Food,' an interactive tactile mat that provides interactive visual responses and induces physical activity in young children at the time of developing tactile and five senses, along with the touch of various stimuli. The product combines fiber materials and digital content to achieve a variety of visual and auditory responses in real time when children touch the fabric. User tests were conducted for 4-year-olds and the result was positive in terms of physical exercise and artistic experience, but quantitative testing is required to generalize it. In the future, we will complement physical and digital contents to realize more complete product.
