摘要

设计活动可以使用灵感刺激(例如,类比,专利等),通过帮助设计师克服僵局或在构思过程中产生具有更积极特征的解决方案来支持。设计研究人员通常会先验地产生灵感刺激,以调查其影响。然而,为了使所选择的刺激具有最大的效用,它应该自动反映设计者当前和正在进行的进展。在这项工作中,设计师在构思过程中接受计算选择的灵感刺激,以回应他们当前解决方案的状态。从相关示例解决方案的广泛数据库中获取,当前设计内容和数据库中概念之间的语义相似性决定了接收到哪些潜在刺激。设计人员根据三种实验条件接受特定的刺激:语义上近的刺激,语义上远的刺激,或者没有刺激(控制)。结果表明,使用潜在语义分析(LSA)可以确定自适应激励刺激,语义相似性测量是实时监测设计过程的一种有前途的方法。使用语义余弦相似值和参与者自我反应评分来验证实现可微分的远近刺激的能力。作为进一步的贡献,本工作还探讨了不同类型的适应性灵感刺激对设计结果的影响。在这里,接近灵感的刺激增加了设计解决方案的可行性。结果还表明,整体激励创新对最终设计结果的显著影响可能大于个体子维度之间的差异。

Computationally Derived Adaptive Inspirational Stimuli for Real-Time Design Support During Concept Generation
Design activity can be supported using inspirational stimuli (e.g., analogies, patents, etc.), by helping designers overcome impasses or in generating solutions with more positive characteristics during ideation. Design researchers typically generate inspirational stimuli a priori in order to investigate their impact. However, for a chosen stimulus to possess maximal utility, it should automatically reflect the current and ongoing progress of the designer. In this work, designers receive computationally selected inspirational stimuli midway through an ideation session in response to the state of their current solution. Sourced from a broad database of related example solutions, the semantic similarity between the content of the current design and concepts within the database determine which potential stimulus is received. Designers receive a particular stimulus based on three experimental conditions: a semantically near stimulus, a semantically far stimulus, or no stimulus (control). Results indicate that adaptive inspirational stimuli can be determined using Latent Semantic Analysis (LSA) and that semantic similarity measures are a promising approach for real-time monitoring of the design process. The ability to achieve differentiable near vs. far stimuli was validated using both semantic cosine similarity values and participant self-response ratings. As a further contribution, this work also explores the impact of different types of adaptive inspirational stimuli on design outcomes. Here, near inspirational stimuli increase the feasibility of design solutions. Results also demonstrate the significant impact of the overall inspirational stimulus innovativeness on final design outcomes, which may be greater than differences across individual sub-dimensions.
