چکیده

ادراک آیکون‌ها به عنوان یکی از مهمترین اجزای رابط کاربر گرافیکی سامانه‌های اطلاعاتی تحت تاثیر عوامل مختلف فردی و محیطی می‌باشدکه از جمله این عوامل می‌توان به مدل ذهنی کاربران اشاره کرد. هدف از این پژوهش، شناسایی عوامل تاثیرگذار بر مدل ذهنی کاربران از آیکون‌های رابط کاربر نرم‌افزارهای کتابخانه دیجیتال ایران است. پژوهش حاضر از حیث هدف، کاربردی است و به شیوه کمّی و کیفی انجام شده است. ابزار گردآوری اطلاعات در بخش کمی، پرسشنامه محقق ساخته و در بخش کیفی، مصاحبه نیمه ساخت‌یافته است. جامعه پژوهش شامل دانشجویان کارشناسی و کارشناسی ارشد رشته علم اطلاعات و دانش‌شناسی دانشگاه شیراز، و کتابداران کتابخانه‌های دانشگاه شیراز و دانشگاه علوم پزشکی شیراز به تعداد 174 نفر است. یافته‌ها نشان داد مهمترین عوامل تاثیرگذار بر مدل ذهنی کاربران از آیکون ها 4 مقوله " تجربه کاربران"، "کارکرد آیکون‌"، "مشخصه‌های  ظاهری آیکون" و "بافت آیکون" می‌باشند. مقوله "تجربه "شامل آشنایی و تجربه قبلی کاربران و مقوله "کارکرد آیکون" شامل تطابق کارکرد آیکون با شکل، اشاره آیکون به کارکرد غیرمتداول  و شناخته‌نشده نسبت به کارکرد متداول، کارکرد مشترک در نرم‌افزارهای مختلف و کارکردهای تخصصی برخی آیکون‌ها می‌شود. مقوله "مشخصه‌های ظاهری آیکون" به رنگ، اندازه، وضوح، زمینه و پیچیدگی آیکون برمی‌گردد. تاکنون پژوهشی در ایران به موضوع عوامل موثر بر مدل ذهنی کاربران از آیکون‌های نرم افزارهای کتابخانه دیجیتال نپرداخته است. شناسایی عوامل موثر بر مدل ذهنی کاربران می‌تواند به طراحان نرم‌افزارهای کتابخانه‌های دیجیتال کمک کند تا آیکون‌هایی طراحی کنند که با مدل ذهنی کاربران مختلف همسویی بیشتری داشته باشد و در نهایت رضایت کاربران را فراهم آورد.

چکیده [English]

Perception of icons is one of the most important elements of graphical user interface in information systems that is affected by personal and environmental factors, including users' mental models. The present study tended to investigate factors affecting on the users' mental models of icons in digital library software. This is an applied research using qualitive and quantitive approach. Gathering data tool in quantitive section is researcher-made questionnaire and in qualitive section is semi-structured interview. The participants consisted of B.A. and M.A. students of knowledge and information science in Shiraz University and Shiraz University of Medical Sciences and Shiraz University librarians, 174 persons. According to the results, " experience", "icons' functions", "external characteristics of icon", and "context" are four main categories affecting on users' mental models of icons. "Experience" includes users' former familiarity and experience and " icons' functions " includes compatibility of icon function with its picture, referring the icon to unknown and uncommon function rather than common function, common function in different applications and special functions of some of icons. " appearance characteristic of icons" includes color, size, clarity, context and complexity of icon. It hasn’t been any research that investigate factors affecting on users' mental models of icons in digital library software. Recognition of factors affecting on users' mental models can help digital library software designers to design the icons that have more consonancy with users’ mental models and eventually provide users satisfaction.
