4. The word universal computing has been invented and coined, Presented by the late Mark Weiser (1952-1999).
5. Several research works have addressed the use of ubiquitous technologies to improve the transport logistics. In this sense, the MobiLab/Unisinos proposed two models called SWTrack and SafeTrack. SWTrack allows companies to track their vehicles and have control over the traveled routes.
6. The use of mobile devices and ubiquitous technologies to support commerce is commonly classified as context-aware commerce or ubiquitous commerce (so called u- commerce). The MobiLab proposed a model for ubiquitous commerce support, called MUCS. MUCS uses the ubiquitous computing technologies to identify business opportunities for users as clients or suppliers.
7. Ubiquitous Games (u-games) In this kind of game, players move to specific places in order to perform tasks. In addition, users interact with each other (multi-player) and with the environment around them (real objects). These interactions are based on wireless technologies that allow users to walk and also to send and receive information such as locations, users nearby and other kind of context-aware data
8. 1. Contexts histories Rosa et al. [11] discussed basic aspects of context awareness and strategies used to best use it. The authors argue that context-aware architectures which use not only present contexts, but also measurements of the past, need to store visited contexts for further use. This information from past contexts related to an entity is called its context history. Some works refer to this history as trail.
9. 2. Profile Management Wagner et al. argued that for an application to adapt itself effectively to users, it is not only important to know the history of contexts visited by them, but to understand who the users are – that is, what are their relevant characteristics. This kind of application organizes its knowledge about a user in User Profiles. The profiles are stored in a format called User Model.

11. Accessibility
11.1. Application : - Ubi Smart Wheel - Ambien Net - MIT Intelligent Wheelchair
12. Learning
12.1. Application : M-Learning
13. Health
13.1. Application: U-Doctor
14. application of ubiquitous computing in health is called u-Health or pervasive health
15. The term Ubiquitous Accessibility was used by Gregg Vanderheiden. The u-Accessibility has emerged as a way to improve the quality of life of people with disabilities and the elderly. Several works can be cited as examples of efforts in this sense, such as AmbienNet, UbiSmartWheel and MIT Intelligent Wheelchair Project.
16. The application of mobile and ubiquitous computing in the improvement of learning strategies has created two research fronts called Mobile Learning and Ubiquitous Learning.
17. RESEARCH OPPORTUNITIES Since the publication of the classical articles of Weiser and Satyanarayanan, the ubiquitous computing has evolved in a significant way, as can be seen in texts dedicated to discuss the area. In this evolution, several research topics have been consolidated, such as locations systems, and location-based services.
18. 3. Context Prediction Rosa et al. affirmed that with the use of the users’ current contexts (present) and their contexts histories (past), applications already have a reasonable information source to base their decisions. Nonetheless, in order to become proactive and act before the context has actually changed, future contexts have to be predicted. This has motivated researchers to study the use of another temporal aspect; the future. The obtainment of the users' future contexts is made through predictions techniques. Based on users’ histories and current contexts, algorithms predict the contexts that probably will describe the users’ future situations.
