摘要

平板电脑等用于绘制草图的数字工具,因能简化设计工作并将大量草图保存在一个地方而广受欢迎。然而,这些工具对设计创造性、新颖性和概念演变的影响尚未得到充分了解。在此,我们介绍一项受控人体研究,在工程设计概念生成练习中评估平板电脑(iPad)对概念新颖性和演变的影响。由于 iPad 的使用速度与纸笔草图相似,我们预计 iPad 的使用不会影响概念的新颖性。我们预计这两种工具在概念演变方面会有不同的模式,即 iPad 用户会比纸笔用户表现出更多的概念迭代(概念演变),这是因为 iPad 的功能便于复制和粘贴之前的草图,然后对其进行修改。我们发现,所使用的工具与概念的新颖性无关。此外,我们还发现两种工具在整体概念演化数量上没有明显差异,但我们发现 iPad 草图的连续概念演化案例多于非连续概念演化案例,而纸笔草图的连续和非连续概念演化案例数量相当。结果表明,总体而言,iPad 可能不会明显抑制设计师的创造技能,因此可以合理地替代纸笔草图,这对设计教育和实践都有意义。

The Influence of Digital Sketching Tools on Concept Novelty and Evolution
Digital tools for sketching, such as tablets, have become popular for streamlining design work and keeping a large quantity of sketches in one place. However, their impact on design creativity, novelty, and concept evolution is not yet well understood. Here, we present a controlled human subjects study that assesses the influence of tablets (iPads) on concept novelty and evolution in the context of an engineering design concept generation exercise. We expect that iPad use will not influence concept novelty due to its similar speed of use as pen and paper sketching. We expect to see different patterns in concept evolution between the two types of tools, namely, that iPad users will demonstrate more iteration on a concept (concept evolution) than pen and paper users due to the fact that iPad features make it easy to copy and paste previous sketches and then modify them. We find that the tool used is not correlated with concept novelty. Additionally, we find no strong differences in overall concept evolution quantities between the two tools, though we see that iPad sketches exhibited more cases of consecutive concept evolution than nonconsecutive whereas paper and pen sketches showed an equal amount of both consecutive and non-consecutive concept evolution. Results indicate that overall, iPads may not significantly inhibit designers' creative skills and thus could be a reasonable replacement for pen and paper sketching, which has implications for both design education and practice.

期刊介绍: The Journal of Mechanical Design (JMD) serves the broad design community as the venue for scholarly, archival research in all aspects of the design activity with emphasis on design synthesis. JMD has traditionally served the ASME Design Engineering Division and its technical committees, but it welcomes contributions from all areas of design with emphasis on synthesis. JMD communicates original contributions, primarily in the form of research articles of considerable depth, but also technical briefs, design innovation papers, book reviews, and editorials.
