A wearable device includes a first radio-frequency identification (RFID) tag, a second RFID tag, one or more feedback devices configured to provide feedback to a guest, and a microcontroller. The microcontroller is configured to generate a first control signal that causes a first type of feedback via the one or more feedback devices in response to interaction between electromagnetic radiation having a first frequency and the first RFID tag and to generate a second control signal that causes a second type of feedback via the one or more feedback devices in response to interaction between electromagnetic radiation having a second frequency and the second RFID tag.

A computer-implemented technique can process overhead images of users in a line at a venue to obtain a user wait time for the line. The processing can include (a) identifying a user of the group of users that is second in the line to obtain a target user, (b) detecting when the target user becomes first in the line to obtain a start time, (c) after the target user becomes first in the line, detecting when the target user leaves the line to obtain an end time, (d) determining a period from the start time to the end time, and (e) calculating the user wait time by calculating a product of (i) the determined period and (ii) a quantity of the group of users in the line after the target user leaves the line. The calculated user wait time can then be output.

There is provided a wireless portable device for providing location-based data to a user in a defined geographical area including a plurality of points of interest, the wireless portable device comprising a wireless transmitter, a wireless receiver, and a display. The wireless transmitter can transmit location information to a wireless server over a wireless network. The wireless receiver can receive location-based data relating to a point of interest from the wireless server periodically and automatically, based on the location of the wireless portable device. By optimizing map routes and schedules using the location-based data and user preferences including wish lists, the wireless portable device can provide helpful recommendations via the display, enabling the user to plan an efficient schedule of activities in the defined geographical area optimized by walking distance, queue wait times, booking and arriving at reserved events, and/or by other user preferences.
