摘要： A method of displaying a map on a wireless communications device includes obtaining map data for rendering the map to be displayed on the wireless communications device, the map data including label data for rendering labels on the map. The device generates a collision-avoidance array representative of the map to be rendered for testing potential label positions prior to actually rendering the labels on the map. The collision-avoidance array is populated by provisionally designating, for each successive label to be rendered, a label space in the collision-avoidance array that corresponds to a map space that is to be occupied by the label on the map. The device then determines whether each successive label to be rendered collides in the collision-avoidance array with any previously designated label spaces. If no collision exists for a given label, the label can be rendered on the map.

摘要： A method in a mobile device for use in receiving updates of network-maintained map data sets is described. The mobile device receives, through a wireless network, map data for rendering a map. The map data has a plurality of layers, where each of the plurality of layers includes a version number and a plurality of data entries associated therewith. Each of the plurality of data entries indicates a plurality of data points for rendering one or more artifacts or labels within an area of interest of the map. The mobile device stores the map data, and displays the area of interest from the plurality of layers of the stored map data. The mobile device then receives, through the wireless network, an indication of an alternative version of one of the layers of the stored map data. When the version number of the alternative version is greater than the version number of the stored version, the mobile device causes one or more requests for the alternative version of said layer for the area of interest to be sent through the wireless network. The mobile device also receives the alternative version of said layer for the area of interest through the wireless network in response to the one or more requests. The mobile device also then causes the map of the area of interest to be rendered in the display in accordance with the combined plurality of layers of the stored map data, but with use of the alternative version of said layer.

摘要： A method of tracking a first wireless communications device using another computing device, such as a second wireless communications device, includes obtaining current position data for the first wireless communications device and obtaining one or more of speed data, time data, and path data for the first wireless communications device. The first wireless device then transmits the current position data and at least one of the speed data, time data and path data to the second wireless communications device or other computing device. In addition to current position data, the speed, path and time data facilitate tracking of the first wireless communications device. When a first mobile user wants a second mobile user to follow him, the first mobile user can put his device in “follow me” (tracking) mode. This is particularly useful when the first and second mobile users are traveling in respective cars or other vehicles.

摘要： Methods and apparatus for dynamically labeling map objects for different views of a visually displayed map are disclosed. For each view of a plurality of different views of a map, a view of the map is rendered “on-the-fly” in a display. The technique is performed by retrieving map data which includes map object graphics data and map object label data; causing one or more portions of a map object (e.g. a road) to be rendered in the view of the display in accordance with the map object graphics data; and also causing a map object label (e.g. a name of the road) to be rendered in the view of the display, in accordance with the map object label data, on or along a portion of the map object between its vertice coordinates, such that a linear position of the map object label on or along the portion of the map object is different from its linear position in each of the other views of the map so that the map object label fits within the view in a continuous moving fashion from view to view. In a specific embodiment, the map object label is rendered by identifying the portion of the map object to be a longest portion of the one or more portions of the map object in the view; identifying a centerpoint of the portion identified to be the longest portion; and causing the map object label to be rendered relative to the centerpoint of the portion identified to be the longest portion.

摘要： Labels can be rendered on a map displayed on a wireless communications device by using pre-rendered characters. The pre-rendered characters can be pre-rotated to one of a number of angular orientations and stored as a variable transparency bitmap for rapid overlaying on the map. The bitmap can include an array or grid of characters wherein each row has a unique orientation, for example, ranging from zero to ninety degrees. Rotations of 90 to 360 degrees can then be achieved by reflecting the characters about vertical or horizontal axes. Overlaying pre-rotated characters is more computationally efficient than computing rotations for each character when rendering the label.
摘要翻译：标签可以通过使用预渲染字符在无线通信设备上显示的地图上呈现。预渲染字符可以预先旋转到多个角度取向中的一个，并存储为可变透明度位图，以在地图上快速重叠。位图可以包括字符的阵列或网格，其中每行具有唯一的取向，例如从零到九十度。然后可以通过反映垂直或水平轴的字符来实现90至360度的旋转。叠加预旋转字符在渲染标签时比计算每个字符的旋转更有效率。
