Publication number: 20110239115Abstract: Disclosed are techniques that allow the user of a mobile device to select an avatar within a virtual world presented on the display screen of the mobile device. In some embodiments, a user manipulates a thumbwheel. As the thumbwheel is turned, the avatars on the display screen are highlighted one after another. The user then presses a thumbwheel button to select a desired avatar. Some embodiments allow the user to select more than one avatar at a time. Several highlighting techniques are available. In some embodiments, the user uses speech commands instead of a thumbwheel to highlight the avatars one by one. Speech input is also used to select one or more avatars. Some devices support a touch-screen interface. Embodiments for these devices allow the user to select an avatar by, for example, drawing an arc enclosing the avatar.Type: ApplicationFiled: March 26, 2010Publication date: September 29, 2011Applicant: MOTOROLA, INC.Inventors: Jay J.

Publication number: 20090254832Abstract: A method and apparatus for collaborative design of a graphical structure is by users of a network. First, a description of the graphical structure is downloaded from a network server to client devices of the users. User modifications of the graphical structure are then uploaded to the network sever from the client devices. The modifications from multiple users are aggregated to produce an aggregated modification, which is then used to update the graphical structure. A description of the modifications may be a text-based description, in which case it is mapped to a numerical description of the modifications. Alternatively, the descriptions of the modifications may be numerical values. The modifications from a plurality of users (received during a specified time period) may be aggregated by calculating a statistical measure of numerical values corresponding to the modifications. The graphical structure may be an avatar, for example.Type: ApplicationFiled: April 3, 2008Publication date: October 8, 2009Applicant: Motorola, Inc.Inventors: Renxiang Li, Jingjing Meng
