Apps use brainwaves to guide, improve meditation

A new smartphone app aims to ease stress and guide users through meditation by monitoring brain waves that change as people become more relaxed.

Transcend, made by the Canadian company Personal Neuro Devices, links the smartphone to a separately sold headset that records electrical activity along the forehead.

'It doesn't matter whether you're meditating as part of a secular practice, or spiritual practice. It all creates the same change in the brain,' said Chad Veinotte, a director of the company, which launched the app last month.

The user picks the duration of time for the meditation and can also opt to listen to a guided audio meditation. A candle graphic in the app grows brighter as the quality of the practice increases, which is determined by brainwaves that indicate relaxation and concentration.

A graph in the app also shows the quality of meditation in real time throughout the session.

'You get to literally look at what's happening in the mind while you're doing the practice,' Veinotte said.

Transcend is one of several apps available for the MindWave headsets made by San Jose, California, company NeuroSky, and which connect to smartphones wirelessly. San Francisco-based company Emotiv Systems also creates headsets that run apps.

NeuroSky's CEO, Stanley Yang, said other uses for the headsets include concentration and focus games.

Veinotte said the headsets, which are also known as brain computer interfaces, will become popular just as sensor-based fitness apps that track distance and speed have.

'We'll see headsets shrink and get more compact and easier to use, and become something you can wear all day every day,' he said.

Headset manufacturers are working on making them more practical for everyday use by integrating them into musical headsets, and by making them more stylish.

'We're going to see an explosion in the types of applications available and the way in which people start paying attention to their minds,' Veinotte said.

The app is available for Android. An iPhone version is expected to be released soon.
