Abstract: A mobile software application implementing “live events,” via which a host of the event may sequentially offer one, two, three, four or more items to a plurality of guests in the event (e.g., via auction, via direct purchase, or via a giveaway). The host's device may obtain and transmit a real-time video stream, which is in turn provided to each guest's device in conjunction with real-time information about the item(s) being offered. Particular techniques protect a guest in a live event from unintentionally performing certain sensitive actions associated with the live event (e.g., placing bids or performing purchases). In particular, user interface elements may require the guest to perform a particular set of user interface interactions to perform the sensitive actions.
