Session 1: Locomotion & Games

Planning Locomotion Techniques for Virtual Reality Games

node-based : selection based

cmp (continuous movement pads)

사용자가 node를 찍은 다음 찍은 node를 continuous하게 teleport하는 방법

vs. RSRT (repeated short ranged teleport- plannnig by showing the next three teleport point) vs. smooth locomotion vs. teleport

결과

CMP는 결과 good (smooth locomotion, teleport와 비슷), RSRT performance 적음,

Versatile Mixed-method Locomotion under Free-hand and Controller-based Virtual Reality Interfaces

technique

• teleport
• grab-move : 손으로 잡고 grag 하듯이 이동 (dog paddle과 비슷)

hand tracking vs. controller

• hand tracking -- pinch zones for teleport and snap turn / hand 로 navigation과 hand manipulation 등을 할 수 있도록

task

long distance, menidum distance, short distance

controller vs. hand tracking teleport

Results

UMUX - usability of ~
grab move - short distance에서 유리.

• qunatitative : controller가 hand보다 좋았음.

Exploring User Engagement in Immersive Virtual Reality Games through Multimodal Body Movements

measuring engagement - self report, physiclogical data, foot move,,,,

engagement and emotions & motivation

• emotions : attention, involvement, percieved connection, cognitive stress emotion
• motivation : defines action tendency
• emotion - movitation

Apporach

multimodal body movement

• head(기기 : EmteqPro), hand (Empatica E4), foot (Foot IMUs)move
• vonlutary (intentional, leg move, hand move) , involuntary (sudden, foot tap, hand fidgest)

measuring

• engagement은 body movment로 측정, emotion, motivation은 coreGRID로 측정

Engagement patterns in VR game

• dissatified with high motivation
• satisfied with medium motivation
• satisfied with lower motivation

Cross-Reality Gaming: Comparing Competition and Collaboration in an Asymmetric Gaming Experience

• cross reality : (VR and PC)

Study design

• immersive platform (VR) vs non-immersive platform (PC)
• competition (fight each other) vs collaboration task (partner work aginst two AI enemy)

Results

• subjective : 대부분 VR condition에서 positive (higher experience)
• objective 에서는 PC가 더 높음 (higher performance)
• collaboration : higher performance

Session 2: Interaction Ⅰ

Does One Keyboard Fit All? Comparison and Evaluation of Device-Free Augmented Reality Keyboard Designs

Comparison

1) gaze & commit keyboard (eye selection, pinch gesture comfirmation)
2) Dwelling keyboard (eye dwelling, handsfree)
3) tap keyboard (손으로 tap)

• Task : copy typing

results

• perforamcne, mental effort : tap > dwell, gaze and commit

• physcial, comfort, relative public usage : dwell > tap, gaze and commit

• keyboard combining more than one input mode can address a user base

Exploring Users’ Pointing Performance on Virtual and Physical Large Curved Displays

• curved display내에서 pointing 하는 것

platform

physical display, virtual display

Results 1

• target width가 작을 수록 movment time이 늘어남

Results 2

• factor : platform, interaction distance, user offset, amplitude, width
• interaction distance(user - display distance :e.g., display radius)에서 center에 있을 수록 movement time이 작음.
• user offset (중심으로부터 떨어진 거리)에 따른 것은 no significant difference

Exploring Unimodal Notification Interaction and Display Methods in Augmented Reality

• notification : visual cue, auditory signal, haptic alert generted by application

Research Question

• RQ1: interaction modality of notification influece taks perfomrnace perception of notification
• RQ2 : how display list for multiple notification influece taks perfomrnace perception of notification
• RQ3 : is there ay statistical connection between interaction modality and notificication

design

interaction x list

interaction

1. eye gaze (dwelling)
2. touch (index finger)
3. voice (button labeled)

list

1. world list
2. hand list

Results

• Time : touch < less, voice / no difference in list
• wrong order : no difference
• SUS : touch > voice , gaze / no differnece in list
• NASA TLX : no difference
• Prefernce : touch > voice, gaze

Intuitive User Interfaces for Real-Time Magnification in Augmented Reality

Design

interaction x scale factor

3 interaction - make magnify window

1. finger binmaual: 손으로 L 모양을 만들고, 양손으로 확대 축소
2. finger unimanual: 한 손으로 L 모양 만들기
3. situated : window창에 있는 2가지 꼭짓점을 drag

5 technique - maginify scale

1. voice (mag 5, mag 10)
2. slider
3. scale by distnace = close to eye - magnify more
4. scale by size(손으로 만든 L모양 크기에 따라)
5. sclae by device (device를 돌려서)

Result

• Questionnaire : NASA-TLX ,SUS,AttrackDiff,UEQ

• interaction - unimanal, bimanul : more novel, hedonic // situated :lower fatigue, mental&physical demand, effort and frustration , more overall performance

• Scale : voice and device rated best - mental demane, physcial demand ...~
