Spatial augmented reality: A tool for operator guidance and training evaluated in five industrial case studies

Spatial Augmented Reality (sAR) as an assistive technology is a promising tool for experienced and novice industrial workers. Five industrial case studies in Dutch manufacturing companies are described to study the effects of sAR assistance on task completion time, learning speed, product quality, work load, technology acceptance and...

Evaluating learning approaches for product assembly Using chunking of instructions, spatial augmented reality and display based work instructions.

Augmented Reality (AR) as an assistive technology is a promising tool for novice operators to learn assembly processes. This experiment compared an AR instruction method to display based electronic working instructions (EWI) for product assembly, to assess learning during the first repetitions of the products. In addition, two types of work...

Considering patient safety in autonomous e-mental health systems - Detecting risk situations and referring patients back to human care

Background: Digital health interventions can fill gaps in mental healthcare provision. However, autonomous e-mental health (AEMH) systems also present challenges for effective risk management. To balance autonomy and safety, AEMH systems need to detect risk situations and act on these appropriately. One option is sending automatic alerts to...

The effects of projected versus display instructions on productivity, quality and workload in a simulated assembly task

In this paper, we describe an experimental study that investigated the effects of electronic work instructions and AR based instructions (projected work instructions) on productivity, product quality and human operator workload. In a simulated assembly task, projected instructions on the work spot and operator guidance picking the correct...

Participation of end users in the design of assistive technology for people with mild to severe cognitive problems; The European Rosetta project

Background: In the European Rosetta project three separate, previously developed, ICT systems were improved and integrated to create one modular system that helps community-dwelling people with mild cognitive impairment and dementia in different stages of the disease. The system aims to support them in daily functioning, monitor (deviations from...

Towards an interactive web tool that supports shared decision making in dementia: Identifying user requirements

To support shared decision making in care networks of people with dementia, an interactive web tool for people with dementia, informal caregivers, case managers and other professional caregivers is being developed. This study aims to identify user requirements for such a tool. A multiple method study with an iterative, participatory design was...

Functional requirements for assistive technology for people with cognitive impairments and dementia

The amount of technological aids on the market to support people in their everyday functioning is increasing. For example mobile telephone, electronic diary, skyping and domotics. Many of these aids are too complicated to operate for people with cognitive impairments, like dementia. For technology to be practicable and useful for them, it will...

Brain-Computer Interfaces: Beyond Medical Applications

Brain-computer interaction has already moved from assistive care to applications such as gaming. Improvements in usability, hardware, signal processing, and system integration should yield applications in other nonmedical areas.

Robots that care

Many countries face pressure on their health care systems. To alleviate this pressure, 'self care' and 'self monitoring' are often stimulated with the use of new assistive technologies. Social robotics is a research area where robotic technology is optimized for various social functions. One of these functions is self care assistance. To foster...

User evaluation of a communication system that automatically generates captions to improve telephone communication

This study examined the subjective benefit obtained from automatically generated captions during telephone-speech comprehension in the presence of babble noise. Short stories were presented by telephone either with or without captions that were generated offline by an automatic speech recognition (ASR) system. To simulate online ASR, the word...

ISO's work on guidance for Haptic and tactile interactions

Tactile and haptic interaction is becoming increasingly important and is no longer restricted to assistive technologies and special purpose computing environments. The technology has gone through numerous breakthroughs and replications and is now entering a period of developing empiricism, the phase in which the first benefits of this new...
