"The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it." Mark Weiser, "Computer for the 21th Century," Scientific American, September, 1991.
Ubiquitous and pervasive computing (UbiComp/PerCom) is how computing will be used in the future. It is about moving beyond the traditional desktop computing model, into embedding computing into everyday objects and everyday activities. The vision is that the virtual (computing) space will be seamlessly integrated with our physical environment, such that we as people cease to take notice of computing artifacts. In this course, we will focus specifically on the following topics to realize this vision of ubiquitous computing:
UbiComp vision and criticism
Smart everyday objects and context awareness
Ambient and tangible interfaces
UbiComp software system
This is a research-level course with the goal to prepare graduate students and senior undergraduate students for research in the area of ubiquitous and pervasive computing. This course will have two main components: paper readings and hands-on projects. The papers will be drawn mainly from recent conference proceedings. In the hands-on projects, students will form teams to explore actual design and prototype of ubiquitous computing systems or applications.

Some programming and hardware experiences (design and prior HCI experience are plus)
The sleeping doll is an interactive doll that assists parents in modifying their child's sleeping habit. A smart phone with accelerometer are used in developing this platform. The sleeping doll works as follows. First, a doll records a bedtime story between a parent and the child. After the bedtime story, the child would hold the hold to sleep. The accelerometer inside the doll detects the child's motion. If a child is moving, the doll stops playing the recorded sound.
The goal of the Mug-Forest is to motivate people to stay hydrated by drinking water regularly and developing a good water-drinking habit. The Mug-Forest project has two parts. The first part is the phone extension, in which a person’s cell phone can be attached (detached) to his/her everyday drinking mug for enabling this service. By using available sensors on a smart phone, the phone can detect who/when/where/what is in a drinking action. For examples, a phone’s accelerometer can be used to detect a drinking action; a phone’s camera can be used to recognize what was the type of drink (i.e., water, soda, etc.); etc. The second part is collaboration, in which many people’s drinking behaviors are virtually linked together to form a “forest”. That is, each user participates by registering his/her phone to our system, and then he/she is designated a “tree” in a forest. His/her drinking habit would affect not only his/her tree but the overall wellness of the forest. We hope to use social collaboration for an effective habit development and behavior persuasion.
In the modern age, people usually suffer from info-stress. They do not pay attention to the priority properly. Therefore, this project aims to develop the Polite UPoster that helps human attention management. In this research, some museum studies were conducted and treated the difference between galleries and public spaces. What is the “polite” interaction? The system sense the human context, then responds with attentive mode or inattentive mode interactions. Additionally, the traditional presentation information is reorganized by the polite way. The polite presentation approach reduces the cognitive load of visitors and augmented geographical and content information intuitively.
The Saving Promoter tracks people’s spending habit and motivate a change in people’s spending behavior. It is an artifact-based persuasive technology implemented on a cell phone. It uses various persuasive technology design principles to tries to help people keep their budget. Moreover with the help of a cell phone’s GPS, the Saving Promoter is location-aware. It records the amount of money people spend on different locations. If they have spent a lot of money on a place, the next time they come near it, the Saving Promoter will remind them that they have already spent too much there.
SpinLoc is a precise indoor localization system by utilizing spinning beacons and Doppler shift effect to target stationary object. We have tested SpinLoc in an indoor garage environment and SpinLoc can achieve a medium error of 39 centimeters and 90% error of 70 centimeters. In the future, we would like to extend SpinLoc to SpinTrack, in order to localize mobile object.
House with Memory explores the possibility of a house that remembers what happens in it. The house ``sees'' through surveillance cameras and ``recollects memories'' to show in display. Though the displayed clips of memory serve no specific persuasive goals, the resident within shall become more aware of his/her life in the house. Also non-residents can get the glimpse of life inside the house.
War-Walking v.s War-Driving:: by Arvin Tsui, Vincent Lin
War-driving is currently the most widely adopted method for building large-scale radio maps in metropolitan Wi-Fi localization. Although the human effort cost for war driving is smaller than that of war walking, its positional accuracy is also lower than that of war walking. This work compares radio maps built from war driving and walking and analyzes how selective map characteristics affect positional accuracy.
