INTRODUCTION
Background
Furthermore, the daily activity of self-reflection, which is usually an internal process, becomes an externalization of the individual's thoughts and feelings (Mols et al., 2016b). Thus, self-reflection in everyday life is not easy and people need encouragement to engage in reflective experiences (Baumer et al., 2014).
Research Goal & Methodology
In addition, living with a reflective attitude has many benefits, such as gaining insight, supporting life change, and motivating behavior change (Li et al., 2010). For example, one study used volumetric changes to represent an individual's daily behavior (Ju et al., 2019).
RELATED WORK
Daily Reflection
- Through an interactive medium
- Through a tangible light object
For example, researchers have proposed a lamp to support the visualization of physical activity levels through a shadow with controlled transparency (Cha et al., 2016). They tried an anthropomorphic design of the lamp in order to maintain high interest in the lamps through user interaction.
Color and Mood
These design examples not only highlighted the value of interacting with light, but also demonstrated the potential for their use as an object of reflection in everyday life. In particular, this approach suggests that interaction with tactile light can be a useful means of reflecting emotional imagery. They also proposed a way for users to customize the color and mood mapping through the app to express their mood with color and share it with others.
They expressed the emotional records such as mood and emotions were expressed in a subtle way, rather than in clear single states (Ståhl et al., 2005), (Figure 7). The above studies suggested the possibility that the color lighting system could contribute to daily reflection by expressing individual mood. Based on the lessons from previous studies, I designed and implemented a device called Lumino, which provides tactile user interaction through color lighting system to support everyday reflection by recording mood with color expression.
LUMINO DESIGN
- Designing a Personal Mood Diary through an Everyday Lighting Artifact
- Separating Mood Record Mode and Show Mode within a Tangible Interface
- Hide the recording interface through slide interaction
- Discard and hide the emotion
- Look back on the records
- Interaction of Lumino
- Slide the plate to the right to record emotions: Record mode
- Slide the plate to the left to display emotions: Show mode
- Implementation
- Software
- Hardware
When the user swipes the tile to the right to record, an interface appears, in which the user selects a color to represent their emotions (Figure 10. a). As the slider moves up, the color becomes brighter with white light added to the plate. In this state, the tile shows the selected color in real time as the user adjusts the button.
In recording mode, the recording dial and slider are visible and the plate shows the chosen color. When the user slides the plate to the left after the recording is completed, the recorded color is displayed simultaneously with the previous recording of the day (Figure 11.a). The user can also swipe a hand in front of the board to delete the recorded moods (Figure 11.c).
USER STUDY
Study Goal
Methodology
- Recruitment
- Participants
- Deployment
- Interview
- Data collection & Data analysis
The criteria ensured that I selected people who were interested in recording and who could continue to archive their daily moods during the experiment. The user determined the best place to place the Lumino, and I asked him during the interview about the reasons for the placement. On the first day of induction, I demonstrated how to use Lumino and provided a 10-minute tutorial booklet to help participants learn all the features and uses of Lumino during the trial period.
In addition, I used Virtual Network Computing remote access software to enable troubleshooting of operational issues during the study. During the weekly interviews, I often asked and heard about the following content: (1) capturing moods with colored light and the mood reflection experience, (2) when and in what context participants used Lumino, (3) the physical interaction experience of Lumino, (4) experiences in the room where participants installed Lumino, (5) exposure to others and its influence on participants' use, (6) general Lumino usage pattern and thoughts after using Lumino, and (7 ) different aspects compared to previously used recording methods. To archive changes in participants' recording patterns, I collected usage logs of their recorded and discarded colors with RGBW values, archived log retrieval dates, and each mode used.
FINDINGS
Toward Better Reflective Experiences in Daily Life
- In and out from emotion reflection
- Privacy and exposure of personal emotions through colored lights
P2 commented: "I think it's good because the sliding and color adjustment features feel like a secret place that only I know how to access. It's nice to be able to hide my diary as well as not open it up for others to see. I felt like I was opening and closing my heart when I opened and closed Lumino because it was controlled with an active interaction." He continued: “It's like logging in and logging out.
When I look at it from a distance, it feels like I'm looking at my emotions one step further. Lumino's features allowed me to look deep into my emotions while recording, but at the same time it helped me not to delve into reflecting my emotions.”. I think it's been a way for me to express myself to my family. Moreover, I could see that the P5,.
Feeling and Handling Archived Daily Positive and Negative Emotions
- Reflection of negative emotions through abstract color light expressions
- Various use patterns according to previous diary writing patterns and tools
- Trials of controlling mood reflections using various interactions in Lumino
At the same time, if they shared the meaning and changed the colors, I found it affected their Lumino usage patterns (eg expressing angry emotion with different colors, such as changing the color to normal white). The pattern was fixed – participants consistently used certain colors to express their specific moods (P3, P4 and P6): These participants recorded the same mood with the same color throughout the experiment. The pattern changed in the middle – participants consistently used certain colors to express their specific moods, but the color changed in the middle of the user study (P2, P5): Two participants usually used the same color for the same mood, but the color changes in the middle of the user study.
One participant used multiple colors for the same mood and did not attempt to map color and mood by changing the color used each day. P4 dismissed the sentiments later that day, noting, "One day something nice happened at the end, so I erased all the colors and threw the record away because I just wanted to have good feelings." She added another experience from the previous day that she thought she would remember again when she saw the negative mood through Lumina. Using the Lumino feature (with more entries, the color ratio of each emotion log becomes smaller), P1 mentioned, “When I have a bad feeling, the color seems to darken.
DISCUSSION
Existing Diary Practices and their Relation to Everyday Mood-Recording Tangible Objects
So, rather than just making mood recordings, it's important to consider how it can be used with other recording methods. They used their existing diaries to write down the causes of moods because the expression of the color may not be well remembered when reflected. In this regard, one study noted that the mood registration of a color can influence the user's experience of its own expression, but it can also be difficult to understand due to the openness of abstract and ambiguous expressions (Ståhl & Höök, 2008).
Thus, it is necessary to explore additional ways to serve as cues when recording moods with ambiguous expressions."
Effects and Possibilities of Reflecting Negative Emotions through Colored Lights
In addition, when physically showing negative emotions, I had to consider how to adjust the level of exposure according to the user's will. According to Nolen et al. deepening negative self-reflection may increase access to negative thoughts and emotions, which may preserve negative moods (Nolen-Hoeksema et al., 2008). Some researchers have also stated that if negative self-reflection occurs frequently, an individual's self-esteem may decrease or cause negative consequences, such as depression (Haaga et al., 1991).
One study highlighted the need for users to stop reflecting or reflect less often to consider the potentially worrying effects of reflection (Mols et al., 2016a). Furthermore, when supporting the reflection of mood recordings, it is necessary to take into account the ambiguity of expression. In line with a previous study (Noh et al., 2020), this abstract visual supported reflection by allowing expressiveness, and its brevity helped to quickly reach the core of the memory.
Designing for Personal Mood Reflective Experiences in Everyday Life
If the user wants to use Lumino as a personal mood log without sharing it with others, the user can choose whether to highlight the color light log of the emotion they recorded in the interface. For use in a shared house, therefore, the design should have shared and private modes that are seen as physical changes in the device. Peripheral awareness as an interaction technique for everyday self-reflection: For natural and consistent self-reflection in everyday life, it is important that the device helps the user perceive his mood-related data.
In this regard, providing peripheral awareness with light bulbs can effectively strengthen mood-related self-reflection. Moreover, since ambient lighting promotes the mood of the environment (Aliakseyeu et al., 2016), unconscious interaction with the lighting device placed in the space can enable users to feel their mood better by creating an environment suitable for self-reflection. Peripheral awareness of self-related data can help users perform daily self-reflection without encumbrance.
LIMITATION & FUTURE WORK
Limitation
Future Work
It does not compromise the benefits of physical objects and allows different scenarios depending on the situation. When the user clicks the calendar icon on the Lumiary home screen (Figure 18.1-a), a calendar briefly appears showing a month's emotional record (Figure 18.2). Clicking on the date briefly displays the timeline of the voting record for that day (Figure 18.3), and clicking on the record displays detailed information (Figure 18.3).
When the user registers his mood in Lumino, a notification appears on the home screen of the application (Figure 18. 1-c). Also, in situations where it is impossible to record in Lumino, such as outside, it is possible to record through the recording icon in Lumary (Figure 18. If additional recording is needed, it is possible through photos and texts in Lumiary (Figure 18 6).
