Smyle Muse includes multiple state-f-the-art, industry first patent pending features that d nt exist in any ther cmmercially available prducts. Further, it is highly custmizable. Therefre, please read this dcument cmpletely t derive the mst benefits ut f using the Smyle Muse. Perceptive Devices LLC All Rights Reserved Page 2 f 9

2. Start up and Calibratin T get the mst benefit ut f using the Smyle Muse, please nte the fllwing. Befre yu begin Watch the Tutrial Vides at least nce. (See link t vides here.) The vides are pretty shrt and it takes less than 15 minutes t watch them all. Given that the Smyle Muse has nvel, patent pending features, time invested in becming familiar with the new cncepts can save a lt f time fr the user. Calibratin prcess Be seated cmfrtably in the frnt f the camera at abut an arm s length distance (18-30 inches). When ready, click the Calibrate and Start! buttn n the Ready t Start Smyle Muse? windw. Lk fr the face detectin indicatr (a rund symbl) shwn t the right f yur muse pinter. Fllwing are the types f indicatr that will be displayed -- : A green smiley indicates that the user s face has been detected. : A pink smiley indicates that while user s face has been detected, things are a bit less than ideal althugh Smyle Muse is still fully functinal. If pssible, face the camera a bit better and/r imprve the lighting cnditins. : A gray circle with a slash indicates that a face was nt detected. Please make sure that the area f the user s face including irises f bth the eyes and muth is visible t the camera. : A red smiley icn means that a face was detected, hwever, with difficulty. Please adjust yur psitin such that the abve-mentined area f yur face is clearly visible. Nte that yu may have t turn s that yur face is pinted in the directin f the camera. Make sure t smile at least fr cuple secnds, while lking at the camera. The smile shuld be mderately strng but nt extreme. It des nt matter if the muth is pen r clsed during the smile. After calibratin is cmplete, maintain similar distance frm the camera (cmpared t the distance during the calibratin), t the extent pssible. Nte that cming clser t the camera increases the muse sensitivity and the reverse is als true. Perceptive Devices LLC All Rights Reserved Page 3 f 9

3. Pinting Pinting means mving the muse cursr / pinter n the screen via head mtins. Please make sure t understand and fllw the belw. On the Smyle Muse Main windw Muse Mtin Mde allws multiple ways fr mving the muse pinter. Chse ne as belw. 1. Always - This is the default mde and is recmmended fr beginners. In this mde, the muse will tend t mve every time the user mves their head. (Whether r nt it will actually mve will depend n ther settings such as Head Tremr and Muse Stickiness, discussed belw.) 2. With Smile In this mde, the muse pinter will start mving based n head mtin nly if the user is als simultaneusly smiling. Once the pinter starts mving, the user can stp smiling and the pinter will cntinue t mve till the user keeps n cntinuusly mving their head. The pinter will park itself nce the user stps mving their head (prvided that they are nt smiling at that time). The benefit f the With Smile mde is that the user has greater cntrl n when the muse pinter starts mving. This leads t higher cmfrt and prductivity. Hwever, additinal skill and/r practice may be required t get prficient in this mde. On the Settings windw [Pinting tab] Muse Sensitivity Adjust this such that the user is able t mve the muse end t end n the display screen with nly mderate and cmfrtable head mtin. A larger setting in Y directin (with respect t the X directin) is recmmended. This is because typically humans have less range f head mtin in the Y directin. Head Tremr Filter Set this t the lwest setting the user can wrk with. We recmmend a setting f 2 if the user has n tremr and has gd cntrl ver their head. Smaller values f this setting allw finer and smther cntrl ver the cursr. Higher settings are recmmended fr users with head tremr. Dwell Park Time Recmmended default is abut 600 millisecnds. Perceptive Devices LLC All Rights Reserved Page 4 f 9

Increase this time if they seem t need mre time t place the cursr precisely. Decrease this time fr faster dwell parking. After the user gets a feel f the dwell park mechanism, they can turn ff the Animate Dwell Park ptin in Preferences tab. Muse Stickiness The cncept f muse stickiness allws the user t naturally mve their head withut the muse pinter leaving its parked lcatin n the screen. This setting indicates the threshld head mtin (speed) needed t make the parked muse pinter mve again. Fr example, t mve and park the muse pinter at the tp right crner f the display screen, the user wuld mve their head in the directin f tp right crner. Once the muse pinter is mved t the desired lcatin, it can be dwell parked s that the user can mve the head back t a mre cmfrtable psitin. The muse will stay put in the parked lcatin as lng as the user mves their head back slwly, that is, at a speed less than the threshld speed defined by the Muse Stickiness setting. Default setting is 20. Lwer settings allws t restart the muse mtin mre easily, but make it harder t leave the muse parked at a particular lcatin. High settings d the reverse. We recmmend the user experiment with this setting t find their sweet spt. Nte: When the user mves their head at a lwer speed than the Muse Stickiness setting, a stickiness indicatr in the frm f a brken yellw ring is shwn arund the muse pinter. The pieces f the ring grw in size as the head mtin appraches the threshld speed (indicated by Muse Stickiness). When the head mtin crsses this threshld, the brken yellw ring becmes a full ring, and the muse pinter starts mving. Many users prefer t nt have muse stickiness when using an n-screen keybard. Smyle Muse therefre disables muse stickiness autmatically when it detects that the On-Screen Keybard (OSK) is active and the pinter is ver the OSK windw. The Disable Muse Stickiness when using On-Screen Keybard setting is prvided t cntrl this autmatic disablement. Muse Stickiness prvides cnvenience as well as reduces the chances f neck strain. It als imprves their prductivity by eliminating the effrt required t cnstantly manage the lcatin f the pinter. Perceptive Devices LLC All Rights Reserved Page 5 f 9

4. Clicking and Dragging Cncept f Easy Drag Mde By default (ut-f-the-bx) Smyle Muse is in the Easy Drag Mde. This mde is designed t make it easy fr users t initiate the drag cmmand. In this mde, whenever the user starts smiling, that results in a muse buttn press, and when the user stps smiling, that results in a crrespnding muse buttn release cmmand. Smyle Muse can be manually put in Easy Drag Mde by setting the Green and Yellw gesture timers t zer value. Als nte that by default Muse Mtin Mde is als set t Always (n the main windw). This means that the muse pinter tends t mve when the user mves their head. Given the abve, by default, if the user happens t mve their head while smiling, the muse pinter mves between the muse buttn press and release, which results in a click and drag cmmand. Whereas, if the user hlds their head reasnably steady thrughut the smile, it results in a click at the lcatin pinted t by the muse pinter. On the Settings windw [Clicking tab] > Advanced Optins Advanced Optins are infrequently used ptins, but can be very useful in certain situatins. Activate Instant Click (in Easy Drag Mde) fr Cerebral Palsy Users Remember that in Easy Drag Mde, when the user starts smiling, that results in a muse buttn press, and when the user stps smiling, that results in a muse buttn release. Hwever, certain users (such as sme peple with Cerebral Palsy), have a difficult time keeping their head steady after initiating the smile. This means that they can end up dragging instead f clicking at the spt at the lcatin f muse pinter when they initiated the smile. This can be frustrating. Activating Instant Click means that Smyle Muse will d a muse buttn press and release instantaneusly (i.e. withut waiting fr the end f the smile t d the release). This results in a click cmmand, instantly at the beginning f the smile. This is can be very useful fr users withut steady head cntrl. Perceptive Devices LLC All Rights Reserved Page 6 f 9

Space Key Instead f Muse Buttn (n Smile) fr Switch Scanning with AAC sftware When this checkbx is activated, smiles result in the space key (n the keybard) t be pressed and released (instead f muse buttn press and release). AAC sftware that can utilize the space key as switch input then can be cntrlled using smiles instead f using a head/ft switch r the like. Please nte the fllwing -- i. Make sure t set yur AAC sftware t accept space key as switch input. ii. In Settings->Gesture Timers tab, make sure all the timers are set t default values. That is, set yur Green and Yellw timer values t zer, and Red timer t 3000 r mre. If the Green r Yellw timers are nn-zer, yu may see Mve Yur Head t Pint, Mve Yur Head t Scrll, etc. messages, that d nt make sense in this switch scanning mde. iii. In Settings->Pinting tab, set Muse Stickiness t 200, and n Settings- >Preferences->Visual Feedback->Muse Mtin Animatin turn ff Animate Muse Stickiness. This will prevent the muse frm mving arund when the user happens t mve their head as well as suppress muse stickiness animatin that culd be distracting during AAC usage. iv. In this mde, start f a smile leads t press f the space key, and end f the smile leads t release f the space key. If the user has cntrl n hw slw/fast they can smile, they can take advantage f generating a distinct switch press frm a switch release signal by smiling in a cntrlled fashin. Sme AAC sftware may be able t use this distinctness t prvide additinal benefit t the user. If yur situatin des nt require distinctin f switch press frm switch release, then cnsider setting the Activate Instant Click checkbx (described in the previus sectin) fr additinal ease f use. v. Smiling in this mde generates different type f sund / beep. If the AAC sftware already generates a sund upn switch press/release, r if s preferred by the user, this sund can be turned ff by ging t Settings- >Preferences tab->audi Feedback->Muse buttn Sunds. (Check ff bth the check bxes.) Perceptive Devices LLC All Rights Reserved Page 7 f 9

5. Truble Shting 1. Smyle Muse smetimes thinks I am smiling when I am nt. Slutin: Try ne r mre f the fllwing Make sure yu are facing the camera when wrking n yur cmputer s that yur lips, nse and irises f bth eyes are visible t the camera withut bstructin. Perfrm a re-calibratin, and make sure yu smile mderately (but slightly strnger than the last calibratin) when prmpted during the prcess. Make sure facial features are being detected crrectly by lking camera view displayed n the main Smyle Muse windw. Crrect the lighting situatin such as lw light r intense backlight, as required. Try using a webcam that perfrms well in lw light. 2. Smyle Muse des nt click instantaneusly. There is a time lag between when I stp smiling and when the click actually cmpletes. Slutin: Try ne r mre f the fllwing Open yur muth slightly when yu stp smiling. This is als a helpful fr ending drag cmmands if they d nt end crisply at the end f the smile. Perfrm a re-calibratin, and make sure yu smile mderately (but slightly strnger than the last calibratin) when prmpted during the prcess. 3. Smyle Muse is nt detecting my face thugh I can see it in the camera view displayed in the main windw. Slutin: Try ne r mre f the fllwing Make sure yu are nt t far away frm the camera. A rugh rule f thumb is t be abut an arms length frm the camera. Crrect the lighting situatin such as lw light r intense backlight. Especially, watch fr large bright areas (such as large bright windws) in the camera view. 4. Difficulty in placing the cursr precisely n a tiny area. I keep n missing the target and ften versht r undersht. Slutin: Try ne r mre f the fllwing-- Increase Dwell Park time. This will prvide yur mre time t fine tune the placement befre the pinter dwell parks. Perceptive Devices LLC All Rights Reserved Page 8 f 9

Reduce Head Tremr Filter. This increases the granularity and smthness f mtin, allwing fr finer placement. Reduce Muse Stickiness value, r even set it t zer. This helps when the final destinatin is clse t the riginal destinatin f the muse pinter. Turn n With Smile Muse Mtin mde n main Smyle Muse windw. Then, keep n smiling while trying t place the pinter precisely by making small head mtins. Stp smiling while hlding the head steady when the pinter is at the desired lcatin. (Yu may want t reduce the Dwell Park time when using the With Smile muse mtin mde.) 5. Difficulty with mving the muse thrugh large distances n the screen. The muse is nt mving far enugh even thugh the user has already turned their neck t the maximum extent. Slutin: Try ne r mre f the fllwing-- Start the head mtin at a higher than average speed (versus starting at lwer than average speed). Higher head speeds mve the muse pinter thrugh disprprtinately larger distances. Increase the Muse Sensitivity setting s that smaller head mtin translates t large muse mtin. While Smyle Muse is running, g t the Micrsft Windws Cntrl Panel and change Muse settings as fllws. i. Turn n Enhance Precisin. ii. If needed, increase Pinter Speed. If yu are using the Always Muse Mtin Mde, set the Muse Stickiness setting (Settings windw > Pinting tab) t abut 20 (r smething yu find cmfrtable). Then, t use a glf analgy, rather than trying t hit hle-in-ne, make mre than ne attempts t get t yur destinatin. That is, in the first attempt, mve the muse twards the destinatin t the maximum extent that is cmfrtably pssible, and let it dwell park. Then pull the head back bit slwly (s that the dwell park muse stays stuck t its new lcatin) and then make anther attempt t bring it clser t r at the final destinatin. Repeat as needed. If yu are using With Smile Muse Mtin Mde, start with the head psitined in an ppsite directin t the directin in which yu wuld like t mve the pinter. Fr example, if yur pinter is in the middle f the screen and yu wuld like t mve it t the right edge f the screen, then pint yur head t the left befre yu begin smiling and mving yur head twards the right. Secndly, yu can als try t mve the pinter t the target thrugh multiple attempts, prgressively getting clser t the target with each attempt. Perceptive Devices LLC All Rights Reserved Page 9 f 9 ----
