Intent

InControl examines the relationship between people, their smart home devices, and the objects they control.

Through the most archaic (and effective) tool, InControl exerts its power upon appliances with the power of punishment and fear. Typical smart home hubs silently pull the strings behind the devices they control, exerting their power silently and without the user’s knowledge. InControl subverts that typical dynamic by displaying that control openly.

When plugged in, InControl seizes the devices in its range, drawing them into its web of influence. Instead of suffering in silence, the devices being controlled viscerally react with discomfort. The alarm clock shrieks and pulses, begging to be freed from control.

Context

The design and concept of InControl originates from a concept in the desire to explore our relationship to our devices and how we control them. In our early ideation, we thought of the relationship between the controlling device and the peripherals as a Master/Pet relationship, with roots in behavioral psychology. B.F. Skinner, a famous psychologist and behaviorist, conducted many experiments showing that animals could be trained to behave in certain ways through the use of rewards and punishments. InControl's use of punishment to control smart home devices could be seen as an extension of this idea, suggesting that we can modify the behavior of our technology in the same way we do with animals.

Prototype/Outcome

Our final outcome was a set of 3 devices: 1 InControl Hub and 2 peripherals, an alarm clock and lamp. When InControl is off, the Alarm Clock and Lamp function normally. However, once InControl is powered on and the bluetooth connection is established, the two peripheral devices fall under its influence and begin exhibiting symptoms of pain. The alarm clock flashes 'SOS,' while the lamp lets out an agonized cry and flashes sporadically.

Process

The initial concept of InControl was not a smart home hub, but rather a smart plug, that could directly connect to the devices under its control using a cable. The "punishment" would involve the smart plug aggressively yanking the cable, like a cruel pet owner yanking the leash of a misbehaving puppy.

However, we soon ran into a technical issue: the motors we were using simply did not have the power to "yank" on something as heavy as an alarm clock or lamp. We then pivoted to another concept, utilizing an LED strip to simulate the shock travelling through the cable and into the peripheral device, causing a shock.

This design had an interactive component with the smart plug, that would result in the cable lighting up more as the user got closer to the smart plug. However, we found this interaction insufficient. The interaction had little to do with our initial concept, and having multiple "cables" entering the alarm clock was confusing to viewers. The concept also required a lot of front-loading story, which required us to stay back and explain to viewers our concept. This led to our decision to create "User Manuals" as stage setting in the final showcase.

Ultimately, this concept was mostly scrapped in favor of a bluetooth connection.

For our new design, we wanted to simplify the interaction, and add a second peripheral to bring home the story. Furthermore, we scrapped the idea of a cable connection and went all-in on bluetooth (this resulted in some connectivity issues later - BLE bluetooth is not fast). We also replaced the screen with a 7 segment display for a more authentic alarm clock visual.

Ultimately, these concept drawings closely approximated the final form of the project.

There were a few changes we had to make due to technical difficulties:

- The alarm clock 7-segment display did not have the capability to display custom letters, only pre-set values, limiting us to an "SOS" message using the numbers 505

- Unfortunately, the BLE sense board did not seem to support the ability to power both the speaker and the 7-segment display. So, we had to instead use the speaker with the lamp, which only had to also power a relay.

- The BLE sense did not have the ability to power both the 7-segment display and the LED strip.

To enhance the stagecraft and world building of the project, we created user manuals and branding to display by the devices.

Open Questions & Next Steps

As for future work, it would be fascinating to explore a system like InControl in an environment outside of the home. Most conversations around IOT center around home appliances, but in reality IOT systems can be widely found in many places, like factories, airports, or even schools. How might these interactions differ? How might people come to understand their environments if the control exerted by a central hub could be widely visualized?

It would also be interesting to explore the inverse concept of InControl. Currently, control is exerted through fear and punishment. But what if instead, devices were rewarded? What form could these rewards take? Would users still be discomforted by the open display of manipulation, or would the interaction seem endearing by comparison?

Reflection

Overall, while our final project deviated significantly from our initial intent, we believe the soul of the project remains. Our initial concept of a central "hub" device that can influence control and terror on the devices in its sphere of influence remained, but our technical challenges with the concept required us to scope back dramatically. Issues with bluetooth connectivity and responsiveness caused the interaction to feel sluggish, even when we managed to get the project working correctly.

However, there were other aspects that we felt were quite successful in the project. The industrial design of all the components was very effective. The ominous black box that contained InControl was effective, and our ability to integrate the modified electronics seamlessly into an existing lamp and alarm clock was extremely effective.

In all, while this project could have used a few more iterations, we felt that it was a success. Its integration with the exhibit space was gorgeous, and the low light really brought forth spooky aspect of the LED strip, flashing lamp, and glowing screen.
