We split up the work, where everyone designs 2-3 haptic patterns, noting down the specific parameter used using the bHaptics Designer interface, special design discoveries or considerations, and possible contexts to use them for.<\/p>\n\n\n\n

Haptic Patterns showcase<\/h3>\n\n\n\n
\n\nOn Thursday, we sat down in a table, each having one glove, and experienced what we all designed. We shared our learnings and brainstormed possible contexts.<\/p>\n\n\n\n
After this, we spent one night thinking about the possible emotions each of the patterns can elicit, so we can start making the next step contextual prototypes.<\/p>\n<\/div>\n\n\n\n

Prioritized patterns -> prototypes<\/h3>\n\n\n\n
On Friday, while going through what each of us brainstormed, we started ranking importance of exploration based on:<\/p>\n\n\n\n
- \n
- What types of effect they will play in the experience?\n
- \n
- Main interaction haptics<\/li>\n\n\n\n
- Supporting feedback<\/li>\n\n\n\n
- Background sensation<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- How difficult it is to implement it?\n
- \n
- Simple no setup<\/li>\n\n\n\n
- Complicated need to test<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

<\/figure>\n\n\n\n<\/p>\n\n\n\n
At the end, we came up with a list of 6 prototypes, those that has potential to be used as main interactions, and has sufficient complexity to test for.<\/p>\n\n\n\n

Playtest Night<\/h1>\n\n\n\n
On Tuesday, we attended our first major playtest night! Our goal is to understand our pipeline for playtesting for onboarding and offboarding using the gloves, as well as try out the exploratory prototypes. <\/p>\n\n\n\n
The script we followed through is the following screenshot.<\/p>\n\n\n\n

\n\n- \n
- Rain\n
- \n
- No palm feedback causes strangeness. People want fingertip and back of hand to feel vibrations too.<\/li>\n\n\n\n
- With only the rain, it felt calming. But music came in, sadness is added to the complex feeling.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
- Elastic band\n

- The action of playing with the band is playful<\/li>\n\n\n\n
- However, imagine tension more than just vibrations<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/div>\n\n\n\n\n
