Smart artifacts have been used to support a range of human-centric services. However, there lacks a study on how to create smart artifact based entertainments in future homes. This research investigates the prospects and issues surrounding designing and playing smart-artifect based games in future homes, which includes a programming platform that allows users to program pervasive games by exploring physical (e.g., smart objects) and virtual (user generated contents, like photos, video clips, and music clips) resources in smart homes.

LogicEasy
- Due to the reasons such as privacy, personality, and acceptability, end users should be allowed to control the context-aware applications in future homes, and even create new applications if they find that existing ones do not meet their needs. There have been several visual programming tools designed for end users, however, the variety and complexity of the
enabled applications is quite low by using them, and the development process is still
a burden to average home users. LogicEasy suggests a multi-level programming environment for users with different abilities, to address the powerful requirement from advanced users and the simplicity requirement from novices.
Home-Explorer
-
Home-Explorer includes several smart-object based applications. (1)
Real-World-Search: This is a web-based indoor physical object search
system. Different from the
Google search targeted in the virtual world, Home-Explorer can help the
human residents quickly localize his belongings (e.g., lost keys).
(2) Smart-Reminder-Agent: People are prone to forget things. For example, one user may forget to take a wallet when he goes shopping. The smart
reminder agent is designed to reduce such difficult situations by
delivering suggestions or alerts to human residents according to various
conditions.

Network Infrastructure

Recent research results show that building and maintaining smart-artifact systems is still a complex and time-consuming task due to the lack of an adequate infrastructure support. To address this, we proposed a new system infrastructure called SS-ONT. Unlike previous studies, Sixth-Sense explores the Semantic Web technology to define a common ontology to assist the development of human-artifact interaction systems. SS-ONT reflects several aspects that have not been discussed in previous ontology-based studies, such as artifact property and status description (e.g., size, location, orientation), and artifact-artifact (e.g., spatial relation) and artifact-human relationships (e.g., object-related human behavior).

Sixth-Sense
-
This research is mainly on how to obtain physical
world information in smart sensor rich environment. The view is
object-centered and we attached sensors to everyday artefacts to create
smart artefacts, which are both self-awareness and ambient-awareness.
Unlike other smart object studies, Sixth-Sense especially addresses the
uncertainty in context-aware systems (owing to the sensor problems such
as sensor is broken, running out of buttery, sensor blockage and limited
coverage), i.e., the so-called hidden object problem. In Sixth-Sense,
hidden objects are detected using a set of user-defined rules (written
in the format of SWRL, a language that is intended to be the rule
language of the Semantic Web). The rules are mainly abstracted from
common sense knowledge and various physical relations among objects.
