小説人物是讀者和文本互動之間的媒介之一，小説家藉由紙上人物在文本上的運作，引導讀者對其人物的認同。本文引自朱甫《人物效應》（L'effet-personnage)理論探討該小說中夢遊型人物的特色，並且從「人稱」（personnel)、 方面，分析葛諾如何運用小説技巧建立和讀者之間的互動模式。

The characters in the novel serve as one of the mediums m the interaction between the reaaer and the text. The novelist guides the readers to understand people in the novel through the operation of the paper figures in the text. This study applies Vincent Jouve's theory of "character effects" in reading Queneau's novel Blue Flowers to explore the features of sleepwalking figures in the novel, and to analyze, from the three functions of the characters—seen as a real person, as a paper figure, and as a pretext between the author and the reader, how Queneau use devices to establish the mode of interaction with readers.
