Hamaguchi Apps for Speech, Language & Auditory Development's groundbreaking app for the iPad is designed for adolescents and adults who would benefit from practice interpreting vocal intonation, facial expressions, body language, and idiomatic or slang expressions. Using real photographs, voices and short mini-video clips of a variety of social situations and expressions, this app provides a dynamic way to help learn and understand the messages that are “between the lines” and simply can’t be replicated with worksheets and static flashcards. American language and body language is used. For more information, watch a demo of this app on YouTube: http://www.youtube.com/watch?v=Y7uV5kMSjko&feature=plcp For easier tasks, geared towards a slightly younger audience, check out Between the Lines Level 1 and Level 2 apps, also in the App store! This app includes 65-75 tasks within each of the three activities. There are three distinct activities in this app: 1. Listening: The user hears a voice speak a sentence, e.g., “What did you DO?!” (Often the same phrase is heard spoken in several different ways throughout the activity, but with different emotion and inflection) The narrator asks, “Who said it?” The user is shown a series of photographs. The user touches the correct facial expression that matches the voice. 2. Body Language: A very short video-clip is shown that depicts an interaction or situation. For example, one teacher makes small talk then asks her colleague, “How is your day going so far?” The other teacher responds with body language only, suggesting “Eh…not bad, not good, just so-so.” The camera closes in this actor and says, “What is she thinking?” The user’s task is to look at the choices of responses and select the one that matches the facial expression/body language. 3. Expressions: A very short video-clip is shown that depicts an actor speaking a sentence that contains an idiomatic or slang expression, e.g., “I want to convince my dad to let me go, but I think I have my word ‘cut out for me’.” The user is then asked, “What does that mean?”A list of slightly cruder slang terms (e.g., "This is BS", "He's not the sharpest tool in the shed") are no longer in the default settings but can be specifically added within the Activity setting. The game can be played by up to 75 users or as a group. The percentage correct is reported for each user’s performance on each of the three activities. Individual users can select their own settings; the group must have the same setting selections for the entire group. Options included: Tracking progress (can be displayed or not) automatic advance or manual advance, choices can be automatically shown or manually displayed. Reward animations are provided at selected intervals for a welcome fun and break including Dunk Tank, Bull’s Eye (darts), and Shoot the Basket.These are not games of skill-just a fun diversion. *Please contact our tech support if you are experiencing any technical issues with our apps at info@hamaguchiapps.com PRIVACY POLICY: We do NOT collect personal data from our users and have no ads.

The full version of Inference Pics expands the experience with 350+ photos and the ability to add your own photos, questions and hints. SOCIAL INFERENCING MADE SIMPLE We make social inferences every day. We use facial expressions, body language, surroundings, and context to work out how someone might be feeling, what they could be thinking, or what may have happened. For some children, teenagers, and adults, noticing these clues and putting them together can be challenging. Inference Pics Lite provides a simple, structured way for speech-language pathologists, teachers, parents, and caregivers to work on social understanding, expressive language, and reasoning skills in speech therapy, education, or at home. SEE WHAT INFERENCE PICS LITE CAN DO • Get learners explaining their thinking, not just giving an answer. • Save prep time with ready-made inference questions, answers, and hints. • Draw directly on photos to circle or highlight important clues. • Show or hide possible answers to adjust the level of support. • Target emotions, perspective-taking, expressive language, and social reasoning. • Practice interpreting facial expressions, body language, and context. • Work with photos of real-life situations, not cartoons. • Create user profiles and track results. • No subscription and no Wi-Fi needed. LOOK. THINK. EXPLAIN. Each inference picture in Inference Pics has two inference prompts/questions. The first question varies depending on the chosen inference activity. For example, in the Conversations activity the user is asked "What are they saying? while in the Seasons activity the inference prompt is "What time of year is it? The second question in each inference activity is always “How can you tell?”. This allows the user to practice verbal expression and giving explanations. It also prompts the child or adult to explain what clues they found to enable them to make an inference.
