learn in this course Who should be taking this course? What you should have installed before starting the class What will be provided to you in class Why custom haptic effects? Introduction to creating custom haptic effects Exploring the sample application Understanding audio files Creating basis effects to compliment the features of audio files Combining multiple basis effects to create a complex timeline effect Exporting haptic effects for implementation into an application Adding custom haptic effects to an Android application Haptic Studio tips and tricks ©2011 Immersion Corporation–Confidential 2
3.
Who should be
taking this course? This course targets experienced Android developers who have completed the course UHL: Adding haptic effects to your Android application. In order to implement custom effects created using Haptic Studio, developers should have practical experience with: Android architecture The life cycle of components Event handling Tween and frame-by-frame animation Debugging an application Deploying an application to a device ©2011 Immersion Corporation–Confidential 3
4.
What you should
have installed before starting the class As an experienced Android developer, you should attend class with these items installed on your computer: Java SE Eclipse Android SDK Android Developer Tools – From within Eclipse’s ―Install new Software‖ option, point toHaptic Studio IMPORTANT NOTE: Before starting the class, you should ensure that Haptic Studio is able to see and communicate with your Android device via Haptic Bridge. ©2011 Immersion Corporation–Confidential 4
5.
What will be
provided to you in class This course focuses on developing and implementing custom haptic effects. You will be provided the code for a simple sample application as well as four audio files that you will use as part of the exercises: – AirplaneCrash_Starter.zip (Eclipse project) – AirplaneCrash_Starter.apk – AirplaneCrash_Solution.zip (Eclipse project) – airplane_snd.wav – running_snd.wav – dying_snd.wav – impact_snd.wav You are also provided a reference library of Haptic Studio effects that can be used as-is or modified for use in your future Haptic Studio effect design projects: Haptic_Studio_Reference_Library.ivs ©2011 Immersion Corporation–Confidential 5
6.
Why custom haptic
effects? Haptic Studio allows you to dramatically enhance the quality of the mobile user's communications experience with custom haptic effects Go beyond the simple haptic effects Allows you to design effects that are perfectly tuned to compliment your project’s audio or visual elements ©2011 Immersion Corporation–Confidential 6
7.
Introduction to creating
custom haptic effects In this course you will be creating not only custom basis effects, but also timeline effects Timeline effects combine basis effects along a timeline Haptic Studio allows you to create custom, timeline effects in one of two ways: – Manually - using the tools within Haptic Studio – Dynamically - using Haptic Studio’s MIDI conversion feature This course if focused on the manual creation of custom haptic effects ©2011 Immersion Corporation–Confidential 7
8.
Introduction to creating
custom haptic effects Haptic Studio simplifies the manual creation of haptic effects to compliment media files by allowing you to import and reference a media file on the same timeline that you are using to create the effect Supported formats are: – AAC (.acc) – K3G (.k3g) – MPEG-4 Audio (.m4a) – MIDI (.mid) – MP3 (.mp3) – MPEG-4 Video (mp4) – SKM (.skm) – Wave (.wav) ©2011 Immersion Corporation–Confidential 8
9.
Exploring the sample
application In the following exercises, you will create custom haptic effects and implement them into a sample application that is based on the animation of an aircraft in flight You will be designing custom haptic effects that allow the user to feel the running engine and the impact of the crash. ©2011 Immersion Corporation–Confidential 9
10.
Exercise 1: Exploring
the sample application In this exercise you will: Explore the Airplane Crash sample application with and without haptic effects Install and run the Airplane Crash starterfile Install and run the Airplane Crash solution file ©2011 Immersion Corporation–Confidential 10
11.
Understanding audio files
Important that you be able to examine audio files and identify key features The Y-axis represents amplitude (volume) and the X-axis represents frequency (the number of cycles/vibrations per a specified amount of time) Higher frequency vibrations are sensed as higher pitched sounds and lower frequency vibrations are sensed as low pitch sounds Easy to shape haptic effects to match audio waveforms Haptic Studio allows you to view audio waveforms and haptic waveforms side-by-side ©2011 Immersion Corporation–Confidential 11
12.
Discussion: Identifying key
features of an audio file and developing a design strategy Keep effects as short as possible Reduces the impact of drift—a phenomena that can cause long effects to become out of sync’ with audio or other media files that they accompany Consider all of the component parts (audio, animation, haptics, interactions, controls, etc.) in advance Then develop a haptic design strategy that will maximize the benefits of haptic feedback ©2011 Immersion Corporation–Confidential 12
13.
Discussion: Identifying key
features of an audio file and developing a design strategy Let’s revisit the sound track from our sample application Airplane Crash Looking at the soundtrack waveform, you should be able to easily identify these key features: engine running, engine dying, silence and impact ©2011 Immersion Corporation–Confidential 13
14.
Discussion: Identifying key
features of an audio file and developing a design strategy Better strategy would be to break it down into three separate haptic effects Elected to divide the soundtrack into three separate sound files—each representing a key feature Straight forward approach will allow our application to simply call the appropriate haptic effect as each individual sound file is played ©2011 Immersion Corporation–Confidential 14
15.
Creating basis effects
to compliment the features of audio files Basis effects can be used alone or combined to form more complex, timeline effect There are three types of basis effects: – Periodic effects are cyclic or pulsing and played at a specific (though variable) frequency – MagSweep effects are constant as opposed to cyclic – WaveForm effects can capture a very high degree of detail from an audio file and require TouchSense 5000 for replay ©2011 Immersion Corporation–Confidential 15
16.
Creating basis effects
to compliment the features of audio files When you add a Periodic or MagSweep effect to your project you will be able to control certain attributes In this course you will deal with: – Magnitude - the strength of the effect—like volume is to audio – Duration - the length of the effect—how long it will play – Attack Time - the amount of time to fade in an effect – Fade Time - the amount of time to fade out an effect When dealing with Periodic effects, you also have control over: – Period - the amount of time from cycle to cycle ©2011 Immersion Corporation–Confidential 16
17.
Exercise 2: Creating
simple basis effects to match the sounds of the running and dying engine In this exercise you will: Select appropriate basis effects for each of the audio files Modify these effects to compliment the sound file Use a timeline to combine audio and haptic effects for testing ©2011 Immersion Corporation–Confidential 17
18.

44.
Exporting haptic effects
for implementation into an application Media files are not embedded in Haptic Studio projects and data exported from Haptic Studio contains no information about media files—they are strictly for development purposes Effects and media files must be re-synchronized at the application level In the case of a complex effect that includes multiple basis effects, the timeline will be called and not the individual effects When you export from Haptic Studio for Android applications, you will either export as an IVT file, or as Java code If you are exporting Java code, omit the effect names if possible ©2011 Immersion Corporation–Confidential 44
45.
Exporting haptic effects
for implementation into an application This is a segment of the Java file produced: ©2011 Immersion Corporation–Confidential 45
46.
Exercise 4: Exporting
haptic effects for implementation into the Airplane Crash application In this exercise you will: Export your Haptic Studio created effects to a Java file ©2011 Immersion Corporation–Confidential 46
47.
Exercise 4: Exporting
haptic effects for implementation into the Airplane Crash application Return to your Airplane Crash Haptic Studio project. Select File > Export > Java Code and save the file as AirplaneEffects.java to your hard drive. When asked about omitting effect names, say no ©2011 Immersion Corporation–Confidential 47
48.
Exercise 4: Exporting
haptic effects for implementation into the Airplane Crash application Adding custom haptic effects to an Android application Adding a custom haptic effect is a multi-step process that includes: – Adding the UHL package, – Adding the native library file – Reading custom haptic effects information into a buffer – Playing the haptic effects on your target device ©2011 Immersion Corporation–Confidential 48
49.
Playing custom effects
To play a custom haptic effect, you must first create a Device object device = Device.newDevice(context); You also need to create an IVTBuffer object before playing the custom effects (IVT is the native file format for Haptic Studio) IVTBufferivt = new IVTBuffer(myeffects.ivt); Once these objects are created and initialized, you can play the actual effect by using the playIVTEffect() method device.playIVTEffect(ivt, myeffects.Periodic); ©2011 Immersion Corporation–Confidential 49
50.
Stopping custom effects
To stop the play of custom haptic effects, you must use the following code: device.stopAllPlayingEffects(); The Device must be closed after it has been used to play and stop the haptic effects. This ensures that there are no resource leaks in the application. device.close(); ©2011 Immersion Corporation–Confidential 50
51.
Exercise 5: Adding
your custom haptic effects to the Airplane Crash application In this exercise you will: Set up an Eclipse project using the Airplane Crash starter file provided Add the custom haptic effects you have created to the sample application ©2011 Immersion Corporation–Confidential 51

Studio tips and tricks Shifting All Timeline Elements – To shift all Timeline elements one way or the other, use ―Ctrl+A‖ to select all elements within the Timeline and then you use your cursor to drag all the elements left or right in the Timeline as you please. Sorting Effects within Timelines – While working within the Timeline view, you may find you want to sort the listed order of multiple objects to for instance, better align vibe events to a referenced waveform profile. Simply select the object name (not the Timeline events) and press your Delete key. Then use the Undo edit option. This will return your deleted Timeline object to the bottom of the Object list. In this way you can reorder the Object list in the Timeline anyway you like. Sorting Effects within the List View – Since Haptic Studio lists effects in the order they were created, you may find you want to reorder the Object in the List View. You can do this by opening a new project and dragging Objects over to the new project in any order that you might want. ©2011 Immersion Corporation–Confidential 79

Appendix D: Haptic
Studio tips and tricks Timelines vs. Non-Timeline Basis effects - It is good practice place each of your new Basis effects, whether they are Periodic or MagSweeps, into Timelines and to rename the Timelines describing their purpose, like ―Menu Click‖ or ―Engine.‖ Once your effect is in a Timeline you have more design options, like: – The ability to browse to a sound file and use that sound file as a reference during your design – The ability to use the repeat looping function – The ability to use the pre-roll function – The ability to use the Basis effect Override function and reuse those Basis effects for multiple Timelines without changing the parameters of the original Basis effect You can reference the ―Haptic_Studio_Reference_Library.ivs‖ effect file to see a good example of this. ©2011 Immersion Corporation–Confidential 80

Appendix D: Haptic
Studio tips and tricks Single Effect Files vs. Multi-Effect Files - It is not necessary to create a new effect file for each effect. You can group any number of effects within one Studio file. The only exception is for ringtone specific effects. The TouchSense API mechanism for playing back an effect Timeline with a ringtone on a handset requires that the effect file have only one Timeline. If there is more than one Timeline in the referenced file, only the first Timeline will be played. Periodic vs MagSweep effects – While MagSweep effects are easier to work with (since they lack the added parameter that allows pulsing), they can limit your creativity. You may want to stick with using only Periodic Basis effects unless you are certain the effect you are creating will remain very smooth (without the need for pulsing or changing frequency parameters). ©2011 Immersion Corporation–Confidential 81

Appendix D: Haptic
Studio tips and tricks Sharp vs Strong Effect Styles – Although Haptic Studio offers three Style modes within the Basis effect editing windows, (Strong, Smooth and Sharp), you will likely find yourself only using the Sharp and Strong modes because they are so different from each other. The Smooth mode is a subtle difference from Strong mode that most users will not be able to differentiate. Periodic Wave Types – Within the Periodic editing window, you have the option of choosing the type of vibration waveform the TouchSense player will simulate. This function is for very high fidelity (like piezo) actuators. Do not choose a Wave Type if you are not designing for piezo actuators, just leave it as it is. But if you are designing for piezo actuators, it is best to use the Sine Wave Type. Sine waves produce strong, yet quiet effects. Actuator Index – If you are not designing for multi-actuator devices, you will never have to change this. This option would allow you to trigger effects on two (or more) actuators at the same time from a single Timeline. ©2011 Immersion Corporation–Confidential 82
