This study investigates the effects of the interplay of device types and the need for touch (NFT) on product attitudes and determines how the mental simulation of touch mediates such relationships. Specifically, we test the roles of instrumental and autotelic NFT in the moderated mediation effect of mental simulation of touch. We instructed the potential participants to shop for a leather jacket on a webpage. With a total of 152 data points from the responses of participants who used a laptop and a touch device that uses a direct-touch interface (e.g., tablets), we conducted descriptive statistics, analysis of variance, and PROCESS procedures using SPSS 20.0. The results show a greater mental simulation for touch when using a touch device than a laptop. When individuals' instrumental NFT is low, using a touch device while shopping online heightens mental simulation of touch, which impacts product attitudes. In particular, such a moderated mediation effect strengthens as the value of individuals' autotelic NFT increases. However, when individuals' instrumental NFT is high, a touch device cannot drive mental simulation for touch, increasing favorable attitudes toward the product.

In recent years, driver information systems (DIS's) became popular and the use of DIS's increased significantly. A majority of DIS's provides touch-screen interfaces because of intuitiveness of the interaction and the flexibility of interface design. In many cases, touch-screen interfaces are mainly manipulated by fingers. In this case, investigating the effect of touch-key sizes on usability is known to be one of the most important research issues, and lots of studies address the effect of touch-key size for mobile devices or kiosks. However, there is few study on DIS's. The importance of touch-key size study for DIS's should be emphasized because it is closely related to safety issues besides usability issues. In this study, we investigated the effect of touch-key sizes of DIS's while simulated driving (0, 50, and 100km/h) considering driving safety (lateral deviation, velocity deviation, total glance time, mean glance time, total time between glances, mean number of glances) and usability of DIS's (task completion time, error rate, subjective preference, NASA TLX) simultaneously. As a result, both of driving safety and usability of DIS's increased as driving speed decreased and touch-key size increased. However, there were no significant differences when touch-key size is larger than a certain level (in this study : 17.5mm).

This paper describes new tactile feedback patterns and the effect of their input performance for a button GUI activated by a tap gesture on mobile touch devices. Based on an analysis of touch interaction and informal user tests, several tactile feedback patterns were designed. Using these patterns, three user experiments were performed to investigate appropriate tactile feedback patterns and their input performance during interaction with a touch button. The results showed that a tactile pattern responding to each touch and release gesture with a rapid response time and short falling time provides the feeling of physically clicking a button. The suggested tactile feedback pattern has a significantly positive effect on the number of typing errors and typing task completion time compared to the performance when no feedback is provided.

This study investigates the interaction effects of mechanical property-based clusters and colorimetric tones on the subjective touch and color sensation of fabrics when sight and touch were simultaneously provided to humans. Each of six different silk fabrics was colored by digital textile printing to have three tones (pale, vivid, and grayish) and its mechanical properties were measured by a Kawabata Evaluation System (KES). Touch and color sensation were identified to be primarily influenced by mechanical property-based clusters and tones, respectively. In touch, 'smooth', 'warm', 'heavy', and 'soft' were found to be affected by interactive effects of mechanical property-based clusters and colorimetric tone so that the pale tone tended to make differences smaller among the clusters for the touch sensation, while the grayish tone seemed to contribute to larger differences of 'heavy'. However, an interaction effect was not found in the color sensation with touch even though the color sensation was also influenced by mechanical property-based clusters.

The purpose of this study is to examine the effects of human touch on turnover intention of ground handling employees at airport. Additionally, this study examines a comprehensive mediating effect of the work schedule and workload between human touch and turnover intention. To examine them, over 700 ground handling employees from six international airports of South Korea were surveyed using the simple random sampling method. The instrument for data collection was a questionnaire, and it was developed based on previous research results. The methodology adopted in this study is the structural equation modeling (SEM). According to SEM analysis, it was proven that both psychological and physical human touch have a significant effect on turnover intention of the employees. Work schedule played a mediating role among all three factors of human touch and turnover intention. However, workload has a mediating effect only between communication human touch and turnover intention. Based on the above findings, theoretical and practical implications are also discussed.

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.

A large amount of processing time is required if the process of detecting the touch position on the touch screen and displaying it on the display panel is performed only by software. In this paper, we propose a method to output information touched on the screen using H/W method in order to improve the response speed delay. In the FPGA module designed for the HDMI signal output to the display module, the touch information is input to the serial data signal including touch coordinate information, point size, and color information. Then the module render the image using HDMI signal input to the module and the touch information. This method has a pipeline structure so it has effect of reducing the delay time that occurs in outputting the touch information compared with the conventional software processing method.

The purpose of this study was to analyze the effect of the structural properties, the color characteristics and the texture of sight and touch on the tactile preferences for the black fabrics. Male and female university students were asked to evaluate the texture of sight and touch and tactile preference to the nine different black fabrics which were selected on the basis of the previous research results. Data were analyzed by using frequency analysis, mean, factor analysis, t-test, F-test, correlation and regression analysis. The texture of sight and touch for black fabrics was classified into four factors: smoothness, bulkiness, extensibility, firmness. This texture of sight and touch factors showed a significant correlative relationship to the structural properties and color characteristics of the black fabrics. There were significant differences according to black fabrics on the point of texture of sight and touch. The velvet was evaluated the most smooth fabric, while the velvet and fake leather were evaluated the most bulky fabrics. Also, the jersey and lace fabrics were evaluated the most extensible fabrics, while the melton was evaluated as the most firm fabrics. There were significant correlative relationships not only between the structural properties and the texture of sight and touch but also between the color characteristics and the texture for black fabrics. Also, among the structural properties, the color characteristics and the texture of sight and touch of black fabrics, major variable factor of influencing on the tactile preference was turned out to be the texture of sight and touch.

The purpose of this study is to examine the compensatory role of instrumental (e.g., product information) and aesthetic (e.g., website background) online cues presented within apparel websites where touch is unavailable. The moderating role of two need for touch (NFT) dimensions (i.e., autotelic and instrumental NFT) between online cues and consumer responses was also investigated. Results demonstrate that personal differences in autotelic and instrumental NFT moderate the relationship between online cues and affective responses. It was found that consumers high in autotelic NFT (i.e., who need to touch for fun) seek more instrumental cues to compensate for lack of touch when shopping apparel products online. Surprisingly, consumers high in instrumental NFT (i.e., who need to touch for product evaluation) use aesthetic as well as instrumental cues to supplement the absence of touch. In contrast, for the low NFT groups, only aesthetic online cues showed significant effects on consumer arousal. Further analysis shows that instrumental NFT is negatively related to purchase intention while autotelic NFT has a positive effect on purchase intention. This implies that need for hedonic-oriented touch is no longer a barrier for online apparel shopping. However, the instrumental NFT seems a significant obstacle for the adoption of online apparel purchasing.
