MiniKin: The Face of Implicit Interaction

About

MiniKin is a virtual pet that resides on the user’s desktop as an ambient presence.

It supports daily routines by using implicit behavioral cues rather than explicit notifications.

MiniKin's Purpose

As a research artifact of my thesis, MiniKin's purpose is to highlight the untapped potential of virtual pets as the face of implicit interaction, pointing towards a new paradigm of UI design.

Concept

An Issue in Current Virtual Pets

Unlike real-life pets, current virtual pets encounter the issue of having a one-sided care dynamic with their users, where they do not reciprocate the care users provide to them.

This may be why virtual pets are unable to sustain long-term user engagement.

A Potential Solution

The following diagram proposes how virtual pets, when equipped with assistive features that support users’ daily routines to showcase reciprocity, establishes emotional connection with their users, who in turn become more receptive of this care.

As this cyclical relationship continues, the strengthening emotional connection further enhances the effective of implicit interactions, thereby sustaining long-term engagement that may surpass that of conventional interfaces.

MiniKin's Role

MiniKin explores this cyclical relationship by revising this one-sided dynamic into a reciprocal one by implicitly showing care through assisting users in their day-to-day lives.

In doing so, MiniKin forms an emotional connection with users, thereby sustaining engagement with its them.

Why not start by giving MiniKin a little pat on the head?

He's waiting by the bottom-right corner of your screen.

You can do so by holding down the right-mouse button and dragging it.

Features

Unlike conventional interfaces, MiniKin delivers its assistive features implicitly. This means, like real-life pets, it conveys its features non-verbally through behavioral cues.

MiniKin would be happy to tell you more about them! Just click on him and ask away.

MiniKin's features are based on real time. Shown below are snippets of how MiniKin will behave at certain times of the day.

Weather Updates

Through outfits, MiniKin informs user of the weather

For example, it wears a raincoat when it is raining.

Event Notifications

On special events, MiniKin will wear an accessory related to the event.

For example, if it is someone’s birthday, MiniKin will wear a party hat.

Wellness Checks

... and stretches every 30-minute mark as silent encouragement for the user to mirror its actions.

Bedtime Reminders

MiniKin dozes off at 11.30pm and sleeps until 7:00am.

It is a quiet indication for the user to go to bed and get sufficient rest.

Evaluation

I conducted individual design research interviews with 6 participants to assess their reaction to MiniKin and whether their interpretations of its behavior align with the intended feature.

During the interview, participants observe MiniKin while I asked them questions on what they can infer from MiniKin's behavioral cues.

Key Insights

While majority recognized what feature MiniKin was trying to convey, there was a level of confusion across all features.

For example, participants recognized that MiniKin wearing a raincoat meant it was raining, but they were unsure what type of rain it was. They prefer MiniKin to wear the gear they themselves would wear to help them infer the type of rain more accurately. These opinions were varied, with no clear universal behavioral cue.

This suggests that if a virtual pet’s behavioral cue is associated with a habit that is absent from the user’s routine or performed in a way that differs from their usual pattern. The user would not be able to interpret it accurately.

All participants reacted positively to MiniKin, displaying a level of fondness for MiniKin, referred to MiniKin as “he” instead of “it”. One participant empathized with MiniKin, saying he looked “uncomfortable” sleeping with his raincoat on, even when there was no change in his expression. She also saw petting MiniKin as a way to feel “more connected” to him.

This suggests that emotional connection may increase users’ receptiveness to a virtual pet’s behavioral cues enabling them to carry out their assistive features more effectively.

Conclusion

I conducted individual design research interviews with 6 participants to assess their reaction to MiniKin and whether their interpretations of its behavior align with the intended feature.

During the interview, participants observe MiniKin while I asked them questions on what they can infer from MiniKin's behavioral cues.
