【摘要】:為了使作戰(zhàn)人員更快速地辨認武器系統(tǒng)顯示界面目標,研究人對不同復(fù)雜程度及大小的目標符號辨認情況,為武器系統(tǒng)顯示界面的目標編碼設(shè)計提供依據(jù)。提出目標符號復(fù)雜度的定義,建立復(fù)雜度計算公式,對符號的復(fù)雜程度進行量化。通過測定被試完成搜尋特定目標的時間,建立反應(yīng)時間和符號復(fù)雜度與大小、高復(fù)雜度目標數(shù)量與大小的線性回歸模型。提取被試辨認不同復(fù)雜度目標的腦電信號,分析腦負荷。結(jié)果表明符號復(fù)雜度越低或尺寸越大,目標越容易辨認;當(dāng)大小一定時,人對復(fù)雜度3以下的目標辨認情況較好,對復(fù)雜度3以上的目標辨認績效明顯下降;腦負荷隨著目標復(fù)雜度的增大而增大。結(jié)論為武器系統(tǒng)顯示界面的符號復(fù)雜度應(yīng)設(shè)計在3以下,高復(fù)雜度目標符號使用時應(yīng)合理調(diào)整其大小。
[Abstract]:In order to make the combat personnel more quickly identify the target of the display interface of weapon system , the target symbol recognition of different complexity and size is studied . The definition of the complexity of target symbol is proposed , and the complexity of the symbol is quantified . The results show that the lower the symbol complexity or the larger the size , the easier the target recognition performance can be achieved . The conclusion is that the symbol complexity of the display interface of weapon system should be designed below 3 , and its size should be adjusted reasonably when the target symbol is high complexity .
