The definition of antipode is the other point on Earth’s surface diametrically opposite to one.
Our team propose a system featuring two interconnected liquid timers, symbolizing connection over distance. Each liquid timer is controlled by a servo for rotation, controlled by a handle. To transmit a signal, a user rotates the handle by 180 degrees. One end of the handle has a magnet, and a hall effect detector registers changes in magnetic status, transmitting a signal to an argon device. The argon then activates the servos on both the local and remote liquid timers, causing them to rotate by 180 degrees and the colorful liquid will slowly descend. Simultaneously, a neopixel behind a translucent acrylic adding a subtle visual element to the communication process. Given that the liquid timer’s rotation is observable for only two minutes, we explore the use of timed, subtle signals as a means of communication.
Reflection
We’ve received a significant amount of feedback on enhancing the user experience. For instance, it’s noted that the initial instinct upon installation is to rotate the clock instead of exploring the magic wand. People seem to have a ingrained perception of interacting with a liquid timer. Despite not wanting to enclose it, the reality is that it’s becoming more of a display, prompting consideration of using a transparent acrylic. This experience highlights the importance of being more decisive in our design approach. Another point of feedback relates to the 2-minute replay effect. When person B receives a signal from person A, finding an efficient acknowledgment method is crucial. While replicating the signal could work, it risks interrupting A’s previous message. To address this, a suggestion is to repeat the action of touching the snoopy with the magic wand, triggering a color change instead of rotating the timer—a quick way for person A to know their message is received.
Other valuable feedback includes slowing down the rotating speed of the timer and swapping the locations of Snoopy and Woodstock. These insights will be considered for future improvements. Reflecting on our three-week experience, we acknowledge underestimating the time required to design, test, and redesign the mechanical aspects, particularly with 3D printing. Consequently, there was a rush to ensure everything was functioning just two hours before the actual presentation.
