10 Fingers Model for Inclusive Design: Towards Accessible Communities for All

2024-10-16T23:21:27+07:00

Inclusive design is a crucial concept for creating an equitable and accessible society for all. This article presents the “10 Fingers Model” for inclusive design. The model uses the 10 fingers as symbols representing key components to consider in the design process. The model comprises 5 physical environment components and 5 human-centered technology components. 5 physical environment components include urban design, landscape design, architectural design, interior design, and product design, components; and five human-centered technology components consist of users, skills, smart devices, software applications, and connectivity. This study was based on a review of relevant literature published between 2000 and 2023. The findings revealed that inclusive design positively impacts quality of life, economy, social participation, innovation, and the environment. It enhances the lives of the elderly and disabled, creates new business opportunities, promotes social inclusion, stimulates innovation, and supports sustainable development. However, implementing this concept in Thailand still faces challenges. Recommendations include raising awareness, developing personnel skills, improving policies and laws, and promoting collaboration among various sectors to create an inclusive society for all in Thai society.

The Development of a Museum Pool Portable Server for Remote Area

2024-04-26T11:26:22+07:00

Visiting museums digitally through smartphones has made accessing information easier for tourists. Museum visitors can access information on exhibited objects freely and privately through the Museum Pool platform which was developed for museum content management. However, this platform relies on the cloud and requires constant internet connectivity. To address this restraint, the researcher has developed a portable server for use with the Museum Pool system. With the server, museum information can be accessed via smartphone even when an internet signal is not available. The study was conducted using an applied research method. The server established a network in the surrounding area using a network path adjustment technique to ensure that visitors could smoothly scan QR codes for data access. From an experiment, the server could support 10-15 users within an access period of 10 seconds. However, if the access period was expanded, the server could support more users. The acceptance error request was set at 10%. Users could either choose to use their internet network or the network from the portable server. The portable servers have been deployed in seven museums since January 2023. Statistical data provided in the appendix indicates constant and practical usage.

Feasibility Study on Fabricating Millimeter-wave Passive Circuits using 3D Printing Technique: Patch Antenna Case Study

2024-06-21T14:10:17+07:00

This article studies the feasibility of utilizing 3D printers to fabricate millimeter-wave passive circuits. In this research, 3D printers were studied and categorized into 3 groups of techniques; Fused Deposition Modeling/ Fused Filament Fabrication (FDM/ FFF), Stereolithography (SLA), and Selective Laser Sintering (SLS). The advantages, disadvantages, and limitations of each technique were analyzed, taking into account their technical competency, workpiece quality, and cost. Subsequently, the potential of creating millimeter-wave circuits using the aforementioned 3D printing techniques was evaluated. The case study involved fabricating a microstrip-fed patch antenna at 40 GHz using each of the three printing techniques. The dimensional variations of the microstrip line and the impact of surface roughness resulting from each 3D printing technique, which could lead to increased losses in the circuit, were also assessed. The study found that FDM/ FFF and SLA techniques were more suitable for fabricating millimeter-wave circuits compared to the SLS technique due to lower dimensional variations and smoother surface finishes, and the performance of the millimeter-wave circuits created met the design.

Nonverbal Emotional Expression Database Development in the Context of Psychological Therapy

2023-10-02T16:31:39+07:00

This study aims to develop a database of nonverbal emotional expressions in the context of psychological counseling. The study focused on two nonverbal expression parameters: expressions conveyed through facial muscles and eye movements, and expressions conveyed through voice modulation. An experimental research method was employed by simulating a psychological counseling scenario among samples. During the 15-25-minute counselling session, each sample was randomly assigned to one mood induction based on the circumplex model of emotion theory. Their nonverbal emotional expressions were recorded in video clips. The records were then identified by individuals and psychologists according to the Facial Action Coding System and analysis of expressions through voice modulation. From the 15-25 minute video clips, the facial expressions dataset contained 3,000-8,000 sequential frames capturing various emotional states, while vocal expressions contained no linguistic meaning as they were incomplete phrases. The emotions identified from the records varied depending on different emotional inductions given to the samples. The nonverbal expression database could be used to develop an Artificial Intelligence (AI) model for emotion recognition exhibited by the Thai population in the provision of mental health services.

Guidelines for Product Placement on Digital Television: Consumer Protection vs Survival of Television Operators

2024-05-16T13:11:52+07:00

This research aims to study the formats of product placement on digital television, explore opinions of stakeholders on the guidelines for product placement, and identify guidelines for product placement in conformity with the NBTC's regulations from the perspective of consumer protection. As a mixed method research, various research methods were employed, including documentation analysis, product placement content analysis, in-depth interviews, survey research, social laboratory research, and panel discussions. The research found that product placement formats on digital television are different from theories in the past. Currently, there are five forms of product placement on digital television, namely product mention, product presence, product experience, product for sale, and supportive VTR. From stakeholders’ opinions, appropriate product placement on digital television should align with program objectives, structure, audience preferences, and ensure factual accuracy. Duration, quantity, and picture size of the advertisement should also be considered. The guidelines for product placement on digital television that conform to the NBTC’s regulations should consider these five factors, namely, types of programs, types of products, formats of general product placement, suitable formats for each type of program, and audience notification on product placement.

Digital Transformation of University Radio Stations

2024-01-19T13:42:13+07:00

This article studies the impact of digital transformation on the operation of university radio stations and how they adapt to the challenges of digital disruption. With a qualitative approach, broadcasting data of university radio stations from relevant research academic articles, websites, and news concerning radio media between 2012 and 2023 were collected and analyzed. The study found that digital technology enables radio media to disseminate similar content across various Internet platforms through streaming systems that can transmit both audio and visual elements via websites or applications. The technology offers live and on-demand listening options. The radio programming format has changed from live broadcast to software-produced online radio programs. In the face of rapid technological changes, university radio stations require comprehensive development in management systems, budget management, and personnel management, particularly integrating digital skills for radio staff to deliver content across multiple platforms. This also involves collaborating with partner networks of radio stations affiliated with other universities in different regions to provide academic knowledge and useful news information to the public.
