摘要：
本文探索使用一种具备位置感知能力、基于空中手势的命令三元组语法来与智能空间交互。该语法受人类语言启发，被构建为带有祈使结构的呼格。在“Light, please switch on（灯，请打开）”这样的句子中，被激活的对象通过模仿其首字母或首字母缩写的手势来调用（呼格，与句子中省略的主语重合）。随后，几何或方向手势识别动作（祈使动词），并可能包含对象特征或用于联网的第二个对象（补语），后者也由首字母或缩写字母表示。在技术层面，一个依赖可训练多设备手势识别层的解释器使二元组/三元组语法解码成为可能。该识别层处理来自可握持设备（智能手机）和徒手设备（智能手表及外部深度相机）的加速度与位置输入信号，并配有专用编译器。在 Living Lab 设施的特定部署中，该语法通过使用源自英语的词典（涉及首字母和首字母缩写）进行实例化。一项包含12名用户的被试内分析，使其能够从可用性、针对对象动作的手势一致性和社会接受度方面分析语法接受度，并评估该手势语法在三种设备实现（可握持、可穿戴和无设备）中的技术偏好。参与者对该语法易于学习及其在管理智能资源方面的潜在有效性表达了共识。在社会层面，参与者在户外活动中偏好 Watch，而在家庭和工作场景中偏好 Phone，这凸显了社会情境在技术设计中的重要性。由于其高效性和熟悉度，Phone 成为手势识别的首选方案。
英文摘要：
This article explores the use of a location-aware mid-air gesture-based command triplet syntax to interact with a smart space. The syntax, inspired by human language, is built as a vocative case with an imperative structure. In a sentence like 'Light, please switch on', the object being activated is invoked via making a gesture that mimics its initial letter/acronym (vocative, coincident with the sentence's elliptical subject). A geometrical or directional gesture then identifies the action (imperative verb) and may include an object feature or a second object with which to network (complement), which also represented by the initial or acronym letter. Technically, an interpreter relying on a trainable multidevice gesture recognition layer makes the pair/triplet syntax decoding possible. The recognition layer works on acceleration and position input signals from graspable (smartphone) and free-hand devices (smartwatch and external depth cameras), as well as a specific compiler. On a specific deployment at a Living Lab facility, the syntax has been instantiated via the use of a lexicon derived from English (with respect to the initial letters and acronyms). A within-subject analysis with twelve users has enabled the analysis of the syntax acceptance (in terms of usability, gesture agreement for actions over objects, and social acceptance) and technology preference of the gesture syntax within its three device implementations (graspable, wearable, and device-free ones). Participants express consensus regarding the simplicity of learning the syntax and its potential effectiveness in managing smart resources. Socially, participants favoured the Watch for outdoor activities and the Phone for home and work settings, underscoring the importance of social context in technology design. The Phone emerged as the preferred option for gesture recognition due to its efficiency and familiarity.
