智慧產品已經偃然成為時代的潮流，現代人已經擁有越來越多有自主感應及推論的科技產品隨伺身旁。然而，卻也同時造成許多使用者的困惑，除了不解機器突發的奇怪行為外，更質疑其基本的感知能力。透過現有產品及概念影片的探討，本研究認為現有智慧型產品在人機互動的溝通上有顯著的落差，導致彼此的誤解。有鑑於此，本研究分為兩個層面進行探討，一是針對智慧系統中，人、機器、系統三者彼此間的互動關係，二是最簡單的燈光如何藉由時序表達語彙的極限，並能呼應到智慧系統的訊息。
第一部分本研究首先收集了40個智慧系統有關的概念設計影片，並從中挑選出7個代表作，整理出機器與機器、機器與系統、系統與系統、及系統與人類等三者間互動的模式及傳遞的訊息共172個情境。經過分析與歸納，本研究整理出基本、一對一溝通、一對群體、群體等不同層級共60個語彙。設計溝通訊息的表達細節，並做出可實際互動的設計物，於會後訪談補足與檢視互動語彙。
以此為基礎，第二部分首先嘗試以模擬系統燈光變化的影片，用問卷方式媒合上述的互動語彙與燈光的連結，並做為參考設計出了5個同一系統下的互動工具，設計師可以操作並設計時序和節奏來改變燈光，並呼應適當的聲音，利用這套工具，本研究設計了能讓使用者了解並操作的智慧系統情境，實驗分為表現型及任務型，並經由實驗結果歸納出5種可對應到語彙的群體燈光設計。本研究結果能夠提供設計師在人與機器或系統間營造良好互動，創造滿意的使用者體驗。

As smart devices become social mainstream, the users are used to interacting with the technologies with sensing and computing capability. However, through surveying existing products and conceptual videos, the gap of communication between users and smart devices was found. In other words, a part of the machines' behaviors is incomprehensible to humans, which lead to confusion, uncertainty and even distrust to the most basic functions of the machines. This work attempted to tackle the very important part of this issue, investigating expressive and understandable multi-single-light expression.

In the first part of our work, analyzing the existing interaction among human, devices and the system, we selected the most representative seven videos among 172 ones. The scenarios in the seven videos were categorized into three types, machines-to-system, system-to-system and system-to-human. Then, we summarized above interaction into 60 vocabulary; including the fundamental, one-to-one, one-to-group and group-to-group communication.

Based on the derived vocabulary, the second part of our work aimed at investigating the expressiveness of multiple point lights, and the design guidelines of which with proper staging. We made videos simulating the light correspond to the vocabulary, whose suitability were further examined on on-line human judgments. Then, we conducted a similar study in a real-world situation with Dial, a developed system containing 5 interactive tools for designers to manipulate and design staging of the lights. In this study, we implemented a series of real light behaviors on physical objects to do the user study, including representative type and assigned type. Finally, five lighting expression with understandable vocabulary were concluded.

The contribution of our work is four-fold: 1) summarizing the vocabulary of lights on smart devices which can serve as design guidelines for future designers, 2) revealing the expressiveness and importance of multiple single lights, 3) concluding the 5 lighting expression with suitable vocabulary, and 4) development of Dial system.
