# BlackBerry Device with QWERTY Keyboard and Trackball Design > This 2012 patent describes a handheld device, like an early BlackBerry, with a QWERTY keyboard and a trackball, focusing on the physical arrangement of keys around the navigation tool. - **Patent:** US 8219158 - **Original title:** Handheld wireless communication device - **Owner:** Research in Motion Ltd - **Granted:** 2012 - **Status:** Active - **Times cited:** 0 - **Field:** consumer_electronics, telecommunications, software ## What it does This patent covers a handheld device designed to be held and used with one hand for typing text messages. It features a display, a keyboard with keys arranged in columns that are offset from each other, and a trackball for navigation. Specifically, it details how at least one key is shaped to fit snugly against the curved edge of the trackball, creating a seamless interface. The device uses a microprocessor to process commands from the keys and trackball to change what's shown on the display. The keyboard layout is a traditional QWERTY, with the top row starting with Q, W, E, R, T. ## What it does NOT cover - Devices that do not have a physical keyboard with alphanumeric keys. - Devices where the keys are not arranged in vertically offset columns. - Devices that do not include a trackball navigation tool. - Keyboards that do not use a QWERTY layout where the top row starts with Q, W, E, R, T. - Devices where keys are not shaped to conform to the boundary of the trackball. ## The clever bit The innovation lies in the precise physical integration of the keys with the trackball. By shaping the edge of at least one key to match the curve around the trackball, the design minimizes wasted space and creates a more ergonomic and visually cohesive input area. ## Real-world examples 1. BlackBerry Curve series 2. BlackBerry Bold series 3. Early BlackBerry smartphones with physical QWERTY keyboards and trackballs ## Why it matters This patent describes the physical design of early BlackBerry devices, which were instrumental in popularizing mobile email and instant messaging. The specific arrangement of keys and the integration of the trackball were hallmarks of the BlackBerry user experience, influencing the design of many subsequent mobile devices. ## Frequently asked questions ### What does BlackBerry Device with QWERTY Keyboard and Trackball Design cover?
