These plans can be of different kinds, and we study here three of them, with different expressive power. Simple plans choose a single service for each request; multi-choice plans instead can cho...
متن کاملIndoor Spatial Updating with Reduced Visual Information.
PURPOSE Spatial updating refers to the ability to keep track of position and orientation while moving through an environment. People with impaired vision may be less accurate in spatial updating with adverse consequences for indoor navigation. In this study, we asked how artificial restrictions on visual acuity and field size affect spatial updating, and also judgments of the size of rooms. M...
متن کاملYPOP Indoor Navigation and Service Information System for Public Environments
A reliable indoor navigation and information system can offer assistance and make the every-day life of many specific user groups, such as the elderly and the visually impaired, easier. However, the same system, if designed well, can also be used by a wide range of new applications and serve as a enabling technology for future ubiquitous mobile applications. This paper describes the ongoing rea...
متن کاملExploiting indoor location and mobile information for context-awareness service
Personal mobile devices such as cellular phones, smart phones and PMPs have advanced incredibly in the past decade. The mobile technologies make research on the life log and user-context awareness feasible. In other words, sensors in mobile devices can collect the variety of user’s information, and various works have been conducted using that information. Most of works used a user’s location in...
