Sustainability studies in tourism are increasingly emphasizing social matters, for instance, “Accessible Tourism for All.” Research on people with visual impairments with smart tourism has so far been sparse. In order to resonate with the global call for sustainable tourism development, this paper aims to contribute to understanding the aspirations of people with visual impairments in terms of tourism and to explore how smart tourism destinations could potentially enhance the tourism experience they offer. We utilized multisensory participant observations and interviews to empathize with the target users and gain insights into their needs. The results showed that they were generally positive about travel, particularly autonomy, achievement needs, and socializing with other individuals. The findings also shed light on their desire to play games on their phones. Consequently, based on the findings and the theoretical groundings of PERMA model and MDA framework from positive psychology and game design, the study proposed a gamified approach to future tourism app design for people with visual impairments, which could enhance engagement, motivation, and enjoyment in the tourism experience.

Privacy is often overlooked in Hong Kong nursing homes with the majority of elderly residents living in shared bedrooms of three to five people. Only a few studies have used Bluetooth low energy indoor positioning systems to explore the relationship between privacy and social interaction among elderly residents. The study investigates the social behavioural patterns of elderly residents living in three-bed, four-bed, and five-bed rooms in a nursing home. Location data of 50 residents were used for the identification of mobility and social interaction patterns in relation to different degrees of privacy and tested for statistical significance. Privacy is found to have a weak negative correlation with mobility patterns and social behaviour, implying that the more privacy there is, the less mobility and more formal interaction is found. Residents who had more privacy did not spend more time in social space. Residents living in bedrooms that opened directly onto social space had higher social withdrawal tendencies, indicating the importance of transitional spaces between private and public areas. Friends’ rooms were used extensively by residents who had little privacy, however, the concept of friends’ rooms have rarely been discussed in nursing homes. There is evidence supporting the importance of privacy for social interaction. Future study directions include considering how other design factors, such as configuration and social space diversity, work with privacy to influence social interaction.

PurposeThe breasts are mainly fatty and connective tissues with no muscles that directly support them, so wearing sports bras is one of the most effective means of alleviating the discomfort of breast movement and potential injury during vigorous physical exercise. However, the design and development processes of traditional sports bras are time-consuming and costly. Hence, a novel method of simulating the static contact pressure between a sports bra and women’s body based on the finite element (FE) and artificial neural network (ANN) models is developed in this study to contribute to the design considerations of sports bras.Design/methodology/approachThree-dimensional FE models of a female subject and sports bras with different fabric properties are developed to determine the amount of contact pressure exerted onto the body. The FE results are then verified by measuring the amount of pressure exerted by the sports bra on the skin with pressure sensors. The Taguchi technique is used to effectively reduce the number of trials from 625 to only 25 cases. These 25 results obtained through FE modelling are then used to provide the training set for the ANNs. Finally, a comparison between the FE and ANN results is carried out.FindingsA novel model of the static contact pressure between a sports bra and human subject based on the FE and ANN methods is presented in this paper. The root mean square error values show that there is only a small difference between the FE and ANN results.Originality/valueThe ANN function established in this study can be used to predict the mechanical behaviours of breasts and has a fundamental impact on the computer-aided design of functional garments in general.

Spinal motor control can provide substantial insight for the causes of spinal musculoskeletal disorders. Its dynamic characteristics however, have not been fully investigated. The objective of this study is to explore the dynamic characteristics of spinal motor control via the fractional Brownian motion mathematical technique. Spinal curvatures and repositioning errors of different spinal regions in 64 children age 11- or 15-years old during upright stance were measured and compared for the effects of age and gender. With the application of the fractional Brownian motion analytical technique to the changes of spinal curvatures, distinct persistent movement behaviors could be determined, which could be interpreted physiologically as open-loop behaviors. Moreover, it was found that the spinal motor control of 15-year-old children was better than that of 11-year-old children with smaller repositioning error and less curvature variability as well as shorter response time and smaller curvature deformation.

This research aimed at investigating the method of using kinetic typography and interactive approach to conduct a design experiment for children to learn vocabularies. Typography is the unique art and technique of arranging type in order to make language visible. By adding animated movement to characters, kinetic typography expresses language meanings in a better and dynamic way. Kinetic typography may also help children to clearly grasp the relationship of difficult words by means of expressing, understanding and experiencing the cognition process. When children interact through the dictionary with animated typeface and movement, it brings on a more functional and profound impression on them for gaining knowledge. The present study takes children’s development and learning theories into consideration by analyzing how they acquire information through interactive process to enhance their involvements. This study shows through the implementation of motion graphics, kinetic typography and information design, that a more diversified learning experience can stimulate and strengthen the sensitivity of children in their perception and learnability. It can also enhance children’s understanding on the meaning of vocabularies, through kinetic expressions.

Effective training to improve serve speed is important for competitive tennis players. The purposes of this study were to investigate the effects of anthropometric factors and whole body kinematics of elite players on ball speed and to propose possible training strategies for improving the quality of tennis serves. Body and racket kinematics of tennis serves of 12 male elite Hong Kong players were investigated. The tennis serve was divided into four phases: I) Back-Swing Phase, II) Lead-Leg-Drive Phase, III) Forward-Swing Phase, and IV) Follow-Through Phase. It was shown that racket-side knee range of motion during phases II and III (r=0.705; p<0.05), racket-side knee peak extension velocity during phase II (r=0.751; p<0.01), racket-side hip peak extension velocity during phase II (r=0.657; p<0.05), racket-side shoulder range of motion in the coronal plane during phase III (r=0.616; p<0.05), racket-side elbow peak extension velocity during phase III (r=0.708; p<0.01) and body mass index (r=0.577; p<0.05) were significantly correlated with ball speed. Body mass index and the identified kinematic parameters that were significantly correlated with ball speed could be used as training guidelines for coaches and players to improve serve speed. Players should pay particular attention in training to increasing the extension velocity and range of motion of the identified joints.

Effective training for improving serve velocity is important for elite tennis players. The objective of this study is to investigate the relationship between whole body kinematics and ball velocity of tennis serve of Hong Kong Elite Tennis players. Twelve Hong Kong Tennis Team male players were recruited. Body kinematics of the players during tennis serves were monitored by a motion analysis system (Vicon MX, Oxford Metric, Oxford, UK) and correlated with the ball velocity. Compared to the Olympic 2000 tennis players, the front knee peak extension velocity, pelvic peak axial rotation velocity, trunk peak right rotation velocity, shoulder peak internal rotation velocity, elbow peak extension velocity and wrist peak flexion velocity of the Olympic players were 5, 2.1, 4.1, 2.9, 2.8 and 2.9 times, respectively, faster than those of the Hong Kong Elite Players. The mean serve velocity of Olympic players (182.9+/-14.0 km/h) was significantly faster than that of the Hong Kong Elite players (145.4+/-19.9 km/h; range: 119-180). The velocity of tennis serve of Hong Kong Elite players was within the range of the lower-level tournament western play-ers. The slower ball velocity of Hong Kong Elite players might be due to the differences in kinematic profile during serve. It was also found that the right shoulder peak internal rotation velocity, right rear knee range of motion, right rear hip peak extension velocity, right shoulder rotation range of motion and body weight were significantly correlated with the ball veloc-ity. Stepwise linear regression analysis showed that the right shoulder peak internal rotation velocity and body weight were significant predictors for ball velocity which contributed 3.8%, 85% respectively to the total variability (r2 = 0.878, p

Motion segmentation and analysis are used to improve the process of classification of motion and information gathered on repetitive or periodic characteristic. The classification result is useful for ergonomic and postural safety analysis, since repetitive motion is known to be related to certain musculoskeletal disorders. Past studies mainly focused on motion segmentation on particular motion characteristic with certain prior knowledge on static or periodic property of motion, which narrowed method's applicability. This paper attempts to introduce a method to tackle human joint motion without having prior knowledge. The motion is segmented by a two-pass algorithm. Recursive least square (RLS) is firstly used to estimate possible segments on the input human-motion set. Further, period identification and extra segmentation process are applied to produce meaningful segments. Each of the result segments is modeled by a damped harmonic model, with frequency, amplitude and duration produced as parameters for ergonomic evaluation and other human factor studies such as task safety evaluation and sport analysis. Experiments show that the method can handle periodic, random and mixed characteristics on human motion, which can also be extended to the usage in repetitive motion in workflow and irregular periodic motion like sport movement.

In this paper, we present an algorithm for motion synthesis. This algorithm is developed as a part of a large crowd simulation project which simulates the motion of the people by using a large database of motion captured data. Most of the crowd simulations divide the simulation process into two phases, the first phase is path generation, and the second phase is matching the motion clip to the generated path. The second phase is the goal of this paper. There are two problems we need to solve for the second phase. The first problem is that the generated motion should be attached to the path, and the speed of the generated motion must be matched with the path. The second problem is that the crowd simulation simulates different size of people, that is, the skeleton is scaled.

In most motion editing approaches, the users often make changes on mocap data by specifying numerical parameters. However, it is not intuitive for a novice to edit motion sequences in motion planning tasks. In this paper, we present a method of notation-based motion editing, in which Labanotation, a well-developed notation language for human movements, is employed as the editing interface. It allows the user to specify the editing requirements via notation score, and the system will semi-automatically generate the desired motion data. The algorithmic steps of its pipeline and the core issues of converting Labanotation into motion sequences are discussed in detail. We show the results of our systems using martial arts motion as its testing data.
