1 Introduction & background Problem:

How can NUI technologies be integrated to broader game categories? Hypothesis:

NUI technologies can replace traditional game interaction by simulating all the manipulations in games.

Purpose:

1 inspire game designers and us to design future game modes for NUI games,

2 adapting NUI for existing game genres.

Goal (one slide): 1 find useful NUI technologies available (or to be) for broader game

categories. 2 find the methods for replacing or enhancing the existing manipulations with

NUI.

2 Methods & Methodologies Qualitative method.

1 Philosophical assumptions: interpretivism

Via social constructions. get basic facts about the situation

2 Analytical research method :

validating hypothesis; analyze the materials

to make an evaluation 3 Inductive approach (reasoning):

gain an understanding of phenomenon & establishing different views of the phenomenon.

4 Research design: Literature review 5 Data collection: Language and Text for interpreting discourse and conversations, and meanings in texts and documents. 6 Data Analysis: Narrative Analysis concerns literary discussion and analysis. 7 Quality Assurrance: (See discussion part)

3 Data collection

sampling： top class research literatures, articles, cases, videos online

selection by keywords: human computer interaction, natural user interface,

eye tracking, speech recognition, NLP, muscle-computer interface, Brain computer interface, body motion interaction, ultrasound, game interaction, user experience, etc..

location: online, including Google, google scholar, KTHB Primo, Springer, etc.

Criteria: 1. feasible real world application & ongoing research; 2. active user control interactions rather than passive ones; to exclude some results.

4 Data analysis

1. Supplement the “advantage and disadvantage” part with our analysis

2. Match the games manipulations with collected NUI technologies

5 Results

1. Eye tracking2. Speech control (unique for possibility to replace keyboard)3. Brain computer interface(promising)4. Image-based body motion interaction(mature, realized a large number of manipulations)5. Muscle-computer interface(promising)6. Ultrasound interaction(promising)

6 Discussion

1. With the combination of them, we can realize most manipulations in traditional games.

2.They do have some flaws which limits the application of them.

3.Most NUI games papers ignore the potential of designing NUI games for disabled people.

4.Keyboard still has no perfect alternatives.

7 Quality assurances/Sustainability

Reliability: based on the reliability of the papers(top journals in the fields)

Validity: Checking the study’s research internally and externally validity

Data sources are reliable and valid

method of data analysis matches our data collection method,

results are meaningful

Replicability: the research may not be replicable, due to researchers’ experience, background and the reviewed literature

Sustainability: the research is sustainable

Conclusions, Future work

NUI technologies can be applied in traditional games, there is no interaction problem in most cases expect online games.

This conclusion may help game designers, our future work could be designing NUI games and participating the optimization of NUI technologies.

Thanks!
