7Project GoalsHow can we make it easier to engage a community of enthusiasts experimenting with embodied cognition – the idea of embedding intelligence in everyday objects within the physical world?

IBM Research

8Project GoalsDesign principle – Approachable Design

- Use of familiar material (cardboard) that can be altered with ease.

- Simplified part assembly: no soldering or adhesive required.

- Simplified programming model and language interface (JavaScript).

IBM Research

9Project OutcomeA prototyping platform to help democratize Embodied Cognition.

Target communities:

- Makers- Developers- Students (Education and Learning)

IBM Research

10How Does Watson Enable TJBot?ListenWatson Speech to Text service converts spoken speech to text that can be analyzed

SpeakWatson Text to Speech service service converts text to sound using various voices.

Understand EmotionsWatson Tone Analyzer service can infer the emotion within text. E.g.. it can tell if a message contains emotions like happy , sad, angry

Understand ConversationsWatson Conversation Service can respond to users in a way that simulates a conversation between humans.

SeeWatson Visual Recognition service can understand the content of an image and describe it.

18Speech to TextConverts audio voice into written text.

• Transcription • Voice-controlled applications: allows for custom

models

https://speech-to-text-demo.mybluemix.net/

IBM Research

19Text To SpeechConverts written text into natural sounding audio in a variety of languages and voices. • Customize and control the pronunciation of specific words to

deliver a seamless voice interaction that catered s to your audience.

• Interactive voice based applications.

https://text-to-speech-demo.mybluemix.net/

IBM Research

20Tone AnalyzerUses linguistic analysis to detect three types of tones in written text: emotions, social tendencies, and writing style. • Understand emotional context in conversations or

communications• Taylor interaction based on sentiment.

IBM Research

21Visual RecognitionUnderstands the contents of images - visual concepts tag the image, find human faces, approximate age and gender, and find similar images in a collection. • Train the service by creating your own custom concepts.

Use Visual Recognition to detect a dress type in retail, identify spoiled fruit in inventory, and more.

IBM Research

22AlchemyLanguage

Analyzes text to help you understand its concepts, entities, keywords, sentiment, and more.

• Additionally, you can create a custom model for some APIs to get specific results that are tailored to your domain.

IBM Research

23ConversationQuickly build, test and deploy a bot or virtual agent across mobile devices, messaging platforms like Slack or even on a physical robot.

• Visual dialog builder to help you create natural conversations between your apps and users, without any coding experience required.

TJBot Library [Beta]- Experimental work to encapsulate basic

functions of the bot.- https://github.com/ibmtjbot/tjbotlib

30The TJBot Library

Encapsulate basic functions for TJBot such as listening, speaking, led color change, waving, seeing.

Open Issues- Improving accuracy- Bot “Interruptibility” - Gracefully managing latency

IBM Research

34Improving AccuracyHow do we improve interaction (voice) accuracy? Improving Speech-to-Text models may not be enough!

- Customized language models?- Intent Matching?- Multi-turn conversations?

IBM Research

35Bot “Interruptibility”When and how should the robot be interrupted (while performing an activity like speaking, waving etc.)?

- Vision? (monitoring a user’s facial expression, raised hand)

- Hardware button or sensor?

IBM Research

36Latency ToleranceLatency can severely degrade quality of interaction. How do we minimize its effect?

- Managing and ordering service responses- Leverage cues to provide additional information- Balancing capabilities – cloud vs local

processing.

IBM Research

37

Next Steps

IBM Research

38Next Steps3 pronged

- Conduct basic research that address open issues.

- Make TJBot simpler and easier to use (tjbotlibrary, visual programming tool)

- Build and sustain the TJBot community.
