This study aimed to analyze consumers' acceptance of sports applications and smart sportswear to better design technology-enhanced walking exercise wear for the Baby Boomer generation based on their cohort characteristics. A questionnaire with items related to acceptance of existing smart sportswear design, functionality, and usability as well as existing sports application design, functionality, and usability was sent to consumers aged 50-65. Of 163 questionnaires distributed, 150 were used for analysis. The results showed that middle-aged consumers were aware of smart sportswear's functional stability, but were concerned about care, durability, and convenience. Middle-aged consumers were also aware of sports applications as educational functions for obtaining new information. Additionally, they found sports applications to have lower perceived convenience and accessibility relative to the young generation, highlighting the need for simple instructions and explanations for sports application planning. Based on these results, we propose "Everyday design for general sportswear," "Functions based on consumer's preference," "Enhanced design for durability and management convenience" for designing and planning walking exercise wear for middle-aged consumers, and "Convenient application organization" and "Educational exercise contents" for application planning for walking exercises.

This study revealed the results related to the functionality of outdoor wear required when man and women in their 30s to 50s engage in outdoor activities. Based on the results of the survey, we proposed composition draft for a smart outdoor jacket with main functions of GPS device and light-emitting device using solar cell and EL. Absorption and release of sweat, functionality regarding rain and wind, and lightweightness, etc. from material functionalities of outdoor wear were found to be important. From function required in clothing for outdoor activity, location tracking, night glow, and lighting functions were found to be most important. For results investigating the necessity of the jacket's location tracking function and lighting function using solar cell, high scores of 3.9~4.0 were given. Purchase intentions for smart outdoor jacket with location tracking and lighting functions devised by this study were fairly positive and most responses indicated that the appropriate purchase price was between 200,000 to 300,000 won while possible problems of this smart outdoor jacket were listed in the order of washing inconvenience, high price, device weight, and discomfort in movement. The draft proposal to integrate with wearable devices for smart outdoor jacket prototype is as follows: Solar cell has been attached to the upper arm but placed inside a transparent pocket which has been detachable for washing convenience while the solar cell and controller have been integrated into a single unit. Using frequent movement exhibited by the arms, EL has been attached along the center line of the raglan sleeve for easy spotting when used as an emergency signal or for night lighting function during outdoor activity. GPS has been attached on the left sleeve so that the person can bend the left arm inward and operate the GPS screen with the right hand while walking or running outdoors.

For the elderly whose path-finding capability and distance perception abilities have been weakened, the study intends to provide UI design of a wrist type walking aid device which allows the elderly to receive both visual and haptic information that induces the elderly' occasional attention by utilizing currently available haptic technology. The study asked 30 the elderly older than 65 years old, target consumers of the technology, to wear a smart watch and find a path by following the directions provided by four different UI versions of Wizard of Oz. Then, the study has conducted post-experience interview. Quantitative analyses was performed their preference level, number of misguided participants and the number of deviations incurred. Based on the data collected, the study has applied grounded theory, a qualitative research methodology, in order to grasp new understanding about the research, and has consequently reached some significant implications for further research on wrist type walking aid device for the elderly, who show self-contradictory demands.

For patients who have senile mental disorder such as dementia, quantity of excercise and amount of sunlight are important clue for dose and the treatment. Therefore, monitoring health information of daily life is necessary for patients' safety and healthy life. Portable & wearable sensor device and server configuration monitoring data are needed to provide these services for patients. Watch-type device(smart watch) which patients wear and server system are developed in this paper. Smart watch developed includes GPS, accelerometer and illumination sensor, and can obtain real time health information by measuring the position of patients, quantity of exercise and amount of sunlight. Server system includes the sensor data analysis algorithm and web server that doctor and protector can monitor through sensor data acquired from smart watch. The proposed data analysis algorithm acquires quantity of exercise information and detects step count in patients' motion acquired from acceleration sensor and to verify this, the three cases with fast pace, slow pace, and walking pace show 96% of the experimental result. If developed u-Healthcare System for dementia patients is applied, more high-quality medical service can be provided to patients.
