HP looks to add colour to cellphones

Hewlett-Packard could soon turn mobile phones into shopping advisors with a colour-matching prototype technology it demonstrated on Wednesday.

The Colour Match mobile service technology, developed by HP Labs, combines colour science, imaging science and mobile networking technology to match colours that complement each other and provide product advice over a cell phone.

The technology can be used in anything that requires the assessment of colour application, said Nina Bhatti, principal scientist at the digital imaging and printing lab in HP Labs. It is particularly applicable to cosmetics, where buyers can use the service to buy a product that matches their skin colour, she said.

Users take a photograph of themselves while holding a specialised colour chart under their face. The picture is sent using MMS (Multimedia Messaging Service) to an "advisory service" on a server. Software on the server seeks out corrections in the image -- it locates the face, adjusts lighting and calibrates the colour.

Then skin pixels culled from a person's face on the corrected image are compared to an existing database of previously analyzed images. Based on the analysis, the advisory service sends a return SMS (Short Message Service) recommending what cosmetic colour and shades would best match the skin colour. The service returned recommendations in a matter of seconds in the demonstration.

Oftentimes stores don't offer the right product to match skin colour, and this mobile application makes the phone a cosmetics advisor, Bhatti said.

Among other applications, the service will be able to make recommendations to match and recommend colours for ties, pants and suits, Bhatti said. Images can be taken with any cell phone camera and the mobile service will work with any service provider.

This service can be implemented by retailers and other consumer goods companies to help users select the products they need, according to HP.
