Using virtual potential fields for electric wheelchair guidance
(IEEE Computer Society, 2002)
TetraNauta is an electric wheelchair guidance system intended for people with heavy motion impairments (such as persons with tetraplegia). It is specially useful when impairments also affect wheelchair steering as it is ...

TetraNauta: a intelligent wheelchair for users with very severe mobility restrictions
(IEEE Computer Society, 2002)
The TetraNauta project is a low cost, fully open steering system to allow people with heavy motor impairments to move in a known environments (hospitals, schools, home, etc.). It minimizes the steering effort, especially ...

Error adaptive tracking for mobile robots
(IEEE Computer Society, 2002)
In mobile robots it is usual that the desired trajectory is memorized or previously generated. When following a trajectory, there are several possibilities attending to the way in which the actual robot state can be related ...

A generalization of path following for mobile robots
(IEEE Computer Society, 1999)
Several authors have proposed some methods for applying path following in specific cases to mobile robots. When we try to extend the path following approach to the general problem several difficulties arise. We present a ...

Promoting accessibility by using metadata in the framework of a semantic-web driven CMS
(Dublin Core Metadata Initiative, 2005)
Web content accessibility for impaired people has been mainly addressed by the Web Content Accessibility Guidelines (WCAG) developed by the Web Accessibility Initiative (WAI) of the W3C Consortium. Those guidelines ...

SIRIUS: Improving the maneuverability of powered wheelchairs
(IEEE Computer Society, 2002)
The indoor maneuverability of powered wheelchairs may be difficult or bothersome in several circumstances. In this paper, we describe an experimental powered wheelchair named SIRIUS, developed at the University of Seville, ...

A parametric formulation of tracking methods: application to chained systems
(IEEE Computer Society, 2004)
When following a path, there are several possibilities attending to the way in which the actual robot state can be related with the whole path. In this work, we formulate different tracking methods on the base that a ...

Performance analysis of single-slave Bluetooth piconets under cochannel interference
(IEEE Computer Society, 2004)
We present an analytical model for single-slave Bluetooth piconets when the coexistence of multiple interfering devices produces collisions. Closed-form expressions for the channel throughput and the mean packet delay are ...
