Volume 2, Issue 3 (12-2014)
Abstract
 

Introduction: Due to the deleterious effects of mismatch between body dimensions of students and educational furniture, this study aimed to assess the size of students’ body in Yazd.

Material and Methods: The study population included all high school students in Yazd city. Popliteal height, buttock-popliteal length, elbow rest height, hips width, thighs thickness and scapular elevation were measured in 307 students. Besides, in furniture used in the schools studied, two chairs and two benches that had a greater frequency of analysis were chosen.

Results: The results of the statistical comparisons showed that type 1 furniture, seat width was acceptable for 96.74% and thigh freedom was 100% fit. The type 2 furniture depth for most students was appropriate, and seat width was acceptable for 96.42% of students. Thigh freedom was fit for 100% with a good rating. In type 3 furniture, there was not any parameter with good fit and in type 4 furniture, wide seat width and thigh freedom was desirable.

Conclusions: In general, the furniture conformity with students’ anthropometry was not desirable.

Mrs. Ramesh Taherian Ojaroud, Dr. Ali Faraji,
Volume 9, Issue 3 (12-2021)
Abstract
Background and Objectives: The jewelry industry accounts for a large share of the income of the people and the government. Workbench and chair are the main tool for manufacturers, designers, art students and repairmen in this field as a group of users for the efficiency of making jewelry. This research seeks to design a workbench and chair for making jewelry that, in addition to being modular, is also interactive and ergonomic.
Methods: This research is practical as well as qualitative-descriptive in nature. It has used a survey method to collect data in which its most important tools in the practical were verbal-visual (questionnaire, interview) and non-verbal (observation). Its design method was the so-call Design up (Tarrahi Nameh in Persian) which has based on interaction design and a user-centered approach. One of the most useful techniques called the hierarchical analysis process (AHP) has been employed to prioritize users and selected designs.
Results: The result of this research is a modular, interactive and ergonomic workbench and chair under the Mosavvab brand. Their users have the advantage of an independent design resulting from its modularity, benefit from usability as well as engagement user experience due to its interactivity and finally, they satisfy from its safety and comfort due to its ergonomics.
Conclusion: This achievement eliminates tangible and intangible problems and not only provides users with personal satisfaction but also reduces the need for many medical treatments. Six elements of usability such as effectiveness, efficiency, safety/comfort, utility, easy to learn and ease to memory, on the one hand, would be brought. The goals of interaction design as visibility, feedback, constraints, consistency, affordance and engaging user experience, on the other hand, would be illustrated.
