Challenge<\/strong><\/p>\n\n\n\nDuring more extensive playtesting this week, we encountered an overfitting issue with the current model. When a gesture outside the 26-letter range is shown, the model mistakenly classifies it as a specific letter with high confidence. We’re addressing this by adjusting the model weights and introducing noise data. Expect further updates on this next week.<\/p>\n\n\n\n
Skeleton Update<\/h2>\n\n\n\n Position, Scale<\/strong><\/p>\n\n\n\nAdditionally, we’ve made improvements to the skeleton. Previously, the skeleton was anchored to the bottom point of the palm, causing it to move unpredictably and resize based on the hand-camera distance. We’ve now recentered it on the palm and constrained the scale, ensuring consistent positioning and size regardless of the hand’s proximity to the camera.<\/p>\n\n\n

New Version<\/figcaption><\/figure><\/div>\n\n\nStyle<\/strong><\/p>\n\n\n\nWe’ve also refined the skeleton style, based on feedback from our client suggesting that simplification could be achieved by removing unnecessary landmark points. Our latest version is clearer and more user-friendly for hand tracking. We plan to further experiment with the color scheme and adjust the size of the tips to finalize an improved version.<\/p>\n\n\n

We’re planning to conduct tests to ensure these items are identifiable by most players. Feedback on the mango, kiwi, and duck has prompted us to revise their images. Additionally, we’re introducing a ‘skip’ option and will display the object’s name as a hint if the player struggles to start spelling within 3-5 seconds.<\/p>\n\n\n
\n
Mini Game 3 Assets<\/figcaption><\/figure><\/div>\n\n\nAll objects are configured in a JSON file, making it straightforward for our client to expand the game’s vocabulary in the future by simply adding a new image and corresponding entry to the JSON file.<\/p>\n\n\n

Json File<\/figcaption><\/figure><\/div>\n\n\nMeeting with Charles<\/h2>\n\n\n\n This week, we had a consultation with Charles, who provided valuable feedback:<\/p>\n\n\n\n
\nLetter Selection Page: The instructions need to be clearer and more concise.<\/li>\n\n\n\n Mini Game 3: Suggests adding more items that are culturally relevant to America.<\/li>\n\n\n\n Background Music (BGM): Future selections should be unobtrusive and comfortable for players.<\/li>\n<\/ul>\n\n\n\nCharles also invited two guests to playtest our game, leading to mostly positive feedback along with some suggestions, which align with our previous discussions.<\/p>\n\n\n\n
Playtesting Experience Goals<\/h2>\n\n\n\n As part of our preparation for next week’s Playtesting Day, we participated in a Playtesting workshop this Wednesday. Following the workshop, we defined our playtesting experience goals and formulated several questions related to these goals:<\/p>\n\n\n\n
Educational Effectiveness<\/strong><\/p>\n\n\n\n\nOn a scale of 1 (I still know nothing) to 5 (I\u2019m very confident in my sign language skills now), how much has your knowledge of the sign language alphabet improved after playing the game?<\/li>\n\n\n\n Were there any specific letters or signs that were difficult to learn through the game? If so, which ones, and why? (Show letters and hint images.)<\/li>\n\n\n\n How helpful was the feedback for correct and incorrect answers during the game, on a scale from 1 (confusing) to 5 (very clear)? (Show game screenshots.)<\/li>\n\n\n\n Did the game’s pacing and difficulty progression align with your learning pace?<\/li>\n<\/ul>\n\n\n\nUser Engagement<\/strong><\/p>\n\n\n\n\nHow enjoyable was the game, on a scale from 1 (not enjoyable) to 5 (very enjoyable)?<\/li>\n\n\n\n Which game elements motivated you the most to continue playing and learning?<\/li>\n\n\n\n Did you ever feel bored or frustrated while playing? If so, please describe when and why?<\/li>\n\n\n\n How likely are you to recommend this game to others interested in learning the sign language alphabet, on a scale from 1 (not likely) to 5 (very likely)?<\/li>\n\n\n\n What improvements or additional features could make the game more engaging for you?”<\/li>\n<\/ul>\n\n\n\nThese questions are designed to gather comprehensive feedback that will inform future enhancements to the game.<\/p>\n","protected":false},"excerpt":{"rendered":"
Parametric Game System Following our discussion last week about the parametric game system, we have extracted several key parameters as listed below. These parameters will be managed through a JSON file, and we will provide a comprehensive document explaining each parameter. This will enable our client to easily modify them in the future.
