Amazon has gone for touch-less gesture recognition in a big way with the release of its long-awaited phone, called Fire.

Amongst other things, one-handed gestures can be used for scroll, tilt and swivel navigation.

Four front face image sensors and four infra-red LEDs form the physical interface, and inside are a dedicated custom processor, real-time computer vision algorithms, and a graphics rendering engine, said the firm.

Gesture recognition is part of something it has branded ‘Dynamic Perspective’.

“Dynamic perspective uses a new sensor system to respond to the way you hold, view, and move Fire, enabling experiences not possible on other smartphones,” claimed Amazon, which is providing a dynamic perspective software design kit (SDK).

Image sensing also plays a part in something called Firefly, which auto-recognises web addresses, email addresses, printed phone numbers, QR codes, bar codes, printed text on signs, posters, magazines and business cards. “Make a call, send an email, save as a contact, or go to the website without typing out URLs or email addresses,” said the firm.

Combined with communications to the firm’s data base, and the phones microphones, Firefly is also said to be able to identify over 100 million items, including movies, TV episodes, songs, and other things amongst its products.

“Later this year, Firefly will include artwork recognition, foreign language translation, and wine label recognition,” said Amazon. Firefly also has an SDK.

The phone’s hardware includes a 2.2GHz quad-core Qualcomm Snapdragon processor with 2Gbyte of RAM and a choice of 32 or 64Gbyte of flash.

The display is 4.7in (12cm), with an ambient light sensor, and wireless interfaces include: nine bands of LTE, four bands of GSM, five bands of UMTS, 802.11ac (and Wi-Fi channel bonding), NFC, and Bluetooth.

As well as the gesture sensors, there are two conventional cameras: at the rear camera is a back-side-illuminated 13Mpixel sensor with LED flash, a five element f/2.0 lens and optical image stabilization (OIS). While at the front is a 2.1Mpixel camera. Both can record 1080p video.

There are two speakers with Dolby Digital Plus for what Amazon describes as “a virtual surround sound experience”.

Case wise, Fire has front and back Gorilla Glass, aluminium buttons, stainless steel details, and a compliant polyurethane grip area.
