## The Ubicomp System Doorman

**Speech based UbiComp system**
**Aim of the Doorman is to:**
- Identify the target of the visitor’s visit or the identity of the staff member
- Open the door and guide the visitors in TAUCHI premises
- Convey personal and organisational messages to staff members
- All the visitors should be served in some way
**Outputs:**
- Speech synthesis
- Anthropomorphic guide robot using pointing gestures
**Inputs:**
- Speech recognition, speaker recognition
- Switches (door, doorbell) and IR sensor
**Based on Jaspis architecture**

## The Doorman system

## The Wizard of Oz Experiment

**Testing the current dialogue and the interaction model, how well they serve the users **
**Part of the iterative design process**
**System fully implemented, only speech recognition missing**
**Speech recognition simulated by a human Wizard**
**A Wizard application for giving manual speech recognition inputs**
**All the speech inputs and system prompts were recorded for analysis and transcripted **
**The behaviour of the users with the robot was observed **

## The Results

**74 cases: 22 visitors, 52 staff members********too little data for generalisation **
**Problems found**
- System prompts too long and annoyingNeeds to be reformed and shortened
- System not competitive with a key System initiative needs to be increased to gain more users

## Conclusion

**The experiment gave valuable information on the actual use and the behaviour of the users**
**Brought up many design issues and problems and help to develope the system further**
**Modularity of the Jaspis architecture made the Woz experiment easy **
**We recommend using the Woz experiments as a part of the iterative design process of UbiComp systems**
