Abstract: Techniques for preventing typographical errors on digital soft keyboards are implemented by a computing device with a touch-screen display. According to one technique, a plurality of soft keys of a soft keyboard is displayed on the touch-screen display. Each soft key covers an area of the touch-screen display. One or more occurrences of a particular typographical error in which a user erroneously selects an adjacent soft key in addition to or instead of an intended soft key are detected. In response, an activation region of the intended soft key is changed to decrease the probability of the user making the same typographical error in the future.

Abstract: A method of determining whether a response received from an electronic device is generated by a person or by an automated software. The method receives a set of capabilities of the electronic device for detecting a group of actions that include at least a gesture or a device movement. The method selects a set of actions based on the device capabilities. The method sends a request to the electronic device for performing the set of actions in the plurality of actions. The method, based on a result of the set of actions performed on the electronic device, determining whether the set of actions are performed by a human.

Abstract: An instant messaging service is operated in cooperation with an event plan manager system. Information is received regarding a planned event from an instant messaging client with which an event organizer is associated and, based thereon, information is provided indicative of the planned event to the event plan manager system. Information is received from the event plan manager system indicative of the planned event, as maintained by the event plan manager system. Invitation instant messages are caused to be provided to instant messaging clients with which invitees of the planned event are associated, wherein the invitation instant messages are correlated to the information indicative of the planned event as maintained by the event plan manager system.

Abstract: Methods and apparatus are described for communicating an online presence of a group in a network. The group includes at least one member associated with the network. Each member of the group has an independent online status. A group presence indicator corresponding to the group is presented in a first interface in the network. The group presence indicator represents an online status of the group as being online or offline. The online status of each member of the group is not apparent from the group presence indicator.

Abstract: Methods and apparatus are described for communicating an online presence of a first user in a network. An online presence indicator is presented in a first interface associated with the first user. The online presence indicator represents an online status of the first user as being online or offline. The online presence indicator further represents a mood of the first user. At least one control is provided in the first interface which is operable by the first user to select the online status represented by the online presence indicator. The at least one control is further operable by the first user to select the mood represented by the online presence indicator. The online presence indicator of the first user is presented to other users in the network.
